Before DENECKE, C.J., and TONGUE[*], LINDE, PETERSON, TANZER and CAMPBELL, JJ.
Plaintiff suffered extensive burns when a pickup truck that she was driving overturned and caught fire. She brought an action for damages against a number of defendants in which she alleged, among other things, that the accident was caused by a defective tire manufactured by defendant Uniroyal, Inc., and mounted on the truck by The Tire Factory. The defendants filed answers alleging that plaintiff's own negligence caused her injuries. Over plaintiff's objections, the trial court submitted these allegations to the jury with instructions to reduce or deny plaintiff's damage claim if plaintiff's injuries resulted in part or predominantly from her own fault. The jury found defendants Uniroyal, Inc. and The Tire Factory at fault to the extent of 55 percent and plaintiff to the extent of 45 percent and awarded plaintiff a corresponding fraction of her total damages.
The Court of Appeals reversed. It held that a recovery of damages for injuries caused by a defective product is not barred or reduced by plaintiff's ordinary contributory negligence under Oregon's proportionate fault statute, ORS 18.470. The court also remanded the case for a new trial because the trial court denied a defense motion to poll the jury. 52 Or. App. 579, 629 P.2d 407 (1981). We allowed review in this case and in Wilson v. B.F. Goodrich, 52 Or. App. 139, 627 P.2d 1280 (1981), also decided today, primarily to decide whether and how the proportionate fault law applies when a dangerously defective product and a plaintiff's negligence together resulted in the plaintiff's injuries. Because it appeared that the question how negligence could be matched against products liability would bear on whether it was meant to be so matched in fixing damages, the Court addressed specific questions on that subject to the parties.I. Prior Development.
Legal developments before the enactment of the present ORS 18.470 in 1975 can be briefly summarized. This court recognized a tort action for injuries caused by a dangerously defective product in a series of cases beginning with Heaton v. Ford Motor Co., 248 Or. 467, 435 P.2d 806 (1967). In 1971, the Legislative Assembly enacted the first version of ORS 18.470 as a comparative negligence statute. In 1973, the court *626 held that recovery on a products liability theory was not barred by a plaintiff's negligence in failing to discover the defect or to take precautions against its possible existence, as distinct from unreasonably using a product known to be defective. Findlay v. Copeland Lumber Co., 265 Or. 300, 509 P.2d 28 (1973) (citing Restatement of Torts 2d, § 402 A, comment n).
The question in Findlay was whether contributory negligence, either of the ordinary kind or of the type sometimes characterized as implied assumption of the risk, was a complete defense to a strict products liability claim. There was no occasion to consider ORS 18.470, which by its terms applied only to negligence actions. A later decision enumerated the elements of assumption of the risk that would make out such a complete defense. Johnson v. Clark Equipment Co., 274 Or. 403, 547 P.2d 132 (1976). After the decision in Findlay, the 1975 legislature made two significant changes in the relevant law. ORS 18.470 was amended to read:"Contributory negligence shall not bar recovery in an action by any person or his legal representative to recover damages for death or injury to person or property if the fault attributable to the person seeking recovery was not greater than the combined fault of the person or persons against whom recovery is sought, but any damages allowed shall be diminished in the proportion to the percentage of fault attributable to the person recovering. This section is not intended to create or abolish any defense."
The same chapter of the 1975 laws also enacted ORS 18.475, which abolished the "doctrines" of "last clear chance" and "implied assumption of the risk." Or. Laws 1975, ch. 599.
We reviewed the foregoing developments and the legislative history of the 1975 amendment in Baccelleri v. Hyster Co., 287 Or. 3, 597 P.2d 351 (1979), in which a forklift truck which lacked an automatic warning signal had backed over the legs of a kneeling worker. A verdict for defendant was reversed because the trial court erroneously submitted a defense of assumption of the risk to the jury. This court went on to state that on a possible retrial, the conduct of the injured worker that was charged as an implied assumption of the risk might instead be a form of contributory negligence to be pleaded and compared as "fault" for purposes of the amended proportionate fault statute, ORS 18.470.II. The present dispute.
Uncertainty about the comparison of "fault" in products liability cases was not wholly laid to rest by Baccelleri v. Hyster Co., supra. Some doubts about the reach of ORS 18.475 remained because Baccelleri dealt with alleged contributory negligence of a kind that defendant had characterized as "implied assumption of the risk." The decision therefore held only that "conduct which was sometimes labeled assumption of the risk but which is a subspecies of contributory negligence can be compared in the apportionment of damages," 287 Or. at 10, 597 P.2d 351, and that "comparative fault is applicable to strict liability in tort;" but it did not reach the question whether defendant had shown "that kind of contributory negligence which can qualify as comparative fault in a strict liability case." 287 Or. at 12, 597 P.2d 351.
The Court of Appeals, faced with this limited guidance, read Baccelleri as extending proportionate fault in products liability cases only to the kind of conduct by plaintiff that previously had been raised as a defense in Findlay v. Copeland and Johnson *627 v. Clark Equip. Co., supra, under the rubric "assumption of the risk," Holdsclaw v. Warren & Brewster, 45 Or. App. 153, 607 P.2d 1208 (1980), and it followed that holding in the present case. Upon careful consideration of the 1975 legislation, however, we conclude that the legislation did not so confine the "fault" on the part of plaintiff to be compared with defendant's "fault," when each was a cause of the injury.
A comparison of ORS 18.470 before and after the 1975 amendment, quoted above, shows the following changes.
First, the 1971 version stated that "[c]ontributory negligence, including assumption of the risk," was not to bar recovery in a negligence action if it "was not as great as the negligence of the person against whom recovery is sought," but plaintiff's damages should be "diminished in the proportion to the amount of such negligence." The 1975 amendment removed the words "including assumption of the risk" from the reference to the "contributory negligence" that was no longer to be a bar. Standing alone, the change might suggest that implied assumption of the risk was once again to bar recovery, although contributory negligence would not. The context and the legislative history, however, show the contrary. More plausibly, the reference to "assumption of the risk" was deleted from ORS 18.470 because the 1975 act abolished the "doctrine of implied assumption of the risk" altogether. ORS 18.475, supra. Far from reintroducing a distinction between the terms "assumption of the risk" and "contributory negligence," the explanations accompanying the bill stated that "contributory negligence" in the statute should be "broadly construed" to include assumption of the risk in the form of unreasonably proceeding to encounter a known danger, which henceforth should be treated like any other contributory negligence. See the sources quoted in Baccelleri v. Hyster Co., 287 Or. at 10, 597 P.2d 351.
Second, the 1975 amendment replaced the reference to an action for "damages for negligence resulting in death or injury to person or property" with one to recover "damages for death or injury to person or property" without limitation to negligence actions. Third, it substituted a comparison of the parties' relative "fault" for their relative "negligence," and also substituted the combined fault of several defendants for the previous reference to a single defendant. Fourth, it cut off the defense of contributory negligence when the injured claimant's fault was "not greater than" that of the defendants' fault rather than when it was "not as great." Fifth, it specified that the "proportion" of the claimant's fault be stated as a "percentage of fault." It left unexplained, however, of what total entity the claimant's fault is to be stated as a percentage. Nor did it provide that this percentage was to be compared with a percentage of fault attributable to defendants. Indeed, the words "compare" or "comparison" do not appear in the statute, which speaks only of diminishing a plaintiff's recovery "in the proportion" of plaintiff's fault. Finally, the amendment added the closing sentence that ORS 18.470 "is not intended to create or abolish any defense."
Removal of the prior reference to negligence actions and substitution of relative "fault" for "negligence" in the allocation of damages extended the principle of proportional fault on both sides to fault other than negligence. As we held in Baccelleri, this included products liability, where the defendants' "fault" lies in putting a dangerously defective product on the market.See Phillips v. Kimwood Machine Co., 269 Or. 485, 525 P.2d 1033 (1974). Nonetheless, the legislative drafters of ORS 18.470 left some textual puzzles. One of these is the *628 effect of the final assertion that ORS 18.470 "is not intended to create or abolish any defense."
As previously stated, prior to the 1975 amendments the Findlay and Johnson opinions, supra, recognized a defense to products liability when the injured party had unreasonably proceeded to encounter a known danger from the defect, a form of conduct which implicitly assumed the risk of injury posed by the known defect. Was ORS 18.470 "not intended to ... abolish" this existing defense? A contrary conclusion emerges from the 1975 amendments as a whole and the apparent thrust of the somewhat self-contradictory explanations that accompanied its enactment.
As far as the statutory text is concerned, implied assumption of the risk was in fact abolished as a defense, not by the 1975 amendment of ORS 18.470, but by section 4 of the same act, which became ORS 18.475, supra note 3. After that enactment, implied assumption of the risk had no further place in Oregon law as a separate "doctrine" for use in pleadings, motions, jury instructions, or findings. See Hornbeck v. Western States Fire Apparatus, 280 Or. 647, 572 P.2d 620 (1977), Thompson v. Weaver, 277 Or. 299, 560 P.2d 620 (1977). But this did not foreclose a claim that, quite apart from that doctrine, the conduct of an injured party who previously might be said to have assumed the risk also was negligent under conventional negligence principles. This is how we understand the statement of Representative Frohnmayer, quoted in Baccelleri v. Hyster Co., 287 Or. at 9, 597 P.2d 351, that "the form of assumption of the risk in which plaintiff voluntarily and unreasonably encounters a known risk ... is unaffected by Section 5 and should be pled as contributory negligence."
It is, however, impossible to square this analysis with the conclusion that only such contributory negligence as previously constituted implied assumption of the risk should be considered "fault" in a products liability case, as the Court of Appeals held. That would have the same statute which abolished implied assumption of the risk in one section revive it as a test of proportional fault in another section. We conclude, therefore, that an injured person's conduct which in fact was a cause of her injury and which constitutes a "fault," including negligence, is to be considered in a products liability action, unless the user's alleged negligence consists in the kind of unobservant, inattentive, ignorant, or awkward failure to discover or to guard against the defect that goes toward making the product dangerously defective in the first place.III. Proportional fault.
A second problem posed by the statute is the question exactly what is to be assessed in determining the "percentage of fault attributable to the person" seeking recovery, and whether that person's fault was "greater than the combined fault of the person or persons against whom recovery is sought." The question has puzzled commentators as well as courts. At least three views are possible.
A. Quantifying "fault." The first is that the formula calls upon the factfinder to assess the relative magnitude of the parties' respective "fault." As stated by a leading textbook on these laws: The process is not allocation of physical causation, which could be scientifically apportioned, but rather of allocating fault, which cannot be scientifically measured." Schwartz, Comparative Negligence 276 (1974). It has been recognized that fault is an evaluation that does not lend itself to quantification, so that a comparison of fault magnifies the subjective elements already intrinsic to the *629 ordinary judgment of negligence. This is true even in assigning proportions to two or more distinct types of negligence, but critics have found a greater theoretical obstacle when the responsibility of one party is grounded in fault other than negligence, or in no fault at all. The obstacle is greater where strict products liability is explained as a device for spreading losses from economic activity regardless of fault, but this court early disavowed that explanation, at least in the absence of legislation. See Phillips v. Kimwood Machine Co., supra, 269 Or. 485, 503, 525 P.2d 1033, Markle v. Mulholland's, Inc., 265 Or. 259, 264-265, 509 P.2d 529 (1973), Wights v. Staff Jennings, 241 Or. 301, 309-310, 405 P.2d 624 (1965). We have said that the "premise of responsibility has settled on strict liability for marketing the dangerously defective product, a premise stricter than negligence but less than absolute liability." Russell v. Ford Motor Co., 281 Or. 587, 594, 575 P.2d 1383 (1978). Whether the "fault" in products liability inheres in the defective product or in the act of placing it on the market, however, difficulties of comparison with the injured party's fault undeniably remain.
B. "Comparative causation." Some courts, applying comparative negligence law to products liability under statutes different from ours or under no statute, have tried to escape the difficulty by stating that the allocation of damages is to reflect relative causation, that is to say, an assessment of the proportion in which the plaintiff's injuries were caused by the product defect on the one hand and by plaintiff's own negligence on the other. See, e.g., Murray v. Fairbanks Morse, 610 F.2d 149 (3rd Cir.1979) (applying Virgin Islands comparative negligence statute) and cases cited at 159-160; Pan-Alaska Fisheries, Inc. v. Marine Const. & Design Co., 565 F.2d 1129 (9th Cir. *630 1977) (admiralty law). They have done so in the belief that this is conceptually more logical or pragmatically easier than to compare the defect of a product with the negligence of one whom it has injured. In Murray v. Fairbanks Morse, for instance, Judge Rosenn wrote for the Third Circuit:"The key conceptual distinction between strict products liability theory and negligence is that the plaintiff need not prove faulty conduct on the part of the defendant in order to recover. The jury is not asked to determine if the defendant deviated from a standard of care in producing his product. There is no proven faulty conduct of the defendant to compare with the faulty conduct of the plaintiff in order to apportion the responsibility for an accident. Although we may term a defective product "faulty," it is qualitatively different from the plaintiff's conduct that contributes to his injury. A comparison of the two is therefore inappropriate...." "We believe that if the loss for a particular injury is to be apportioned between the product defect and the plaintiff's misconduct, the only conceptual basis for comparison is the causative contribution of each to the particular loss or injury. In apportioning damages we are really asking how much of the injury was caused by the defect in the product versus how much was caused by the plaintiff's own actions...."
610 F.2d at 159. With due respect to these courts, however, we are not persuaded that the concept of "comparative causation" is more cogent or meaningful than comparative fault, if by "causation" is meant some relation of cause and effect in the physical world rather than the very attribution of responsibility for which "causation" is to serve as the premise.
Both the defect and the plaintiff's fault must in fact be causes of one injury before a question of apportionment of fault arises. Although defendants in this case had completed all acts necessary for liability when they manufactured and mounted a dangerously defective tire that might blow out and overturn the Sandford pickup, they obviously would not be liable if the pickup overturned for some unrelated reason. Similarly, it would not matter that a driver operated his car unlawfully or recklessly if he was injured by an explosion due to an electrical defect that would have occurred with the same harmful consequences if the car had been standing still. In less obvious situations where the physical course of events is in doubt, if either party convinces the factfinder that its misconduct in fact was not a cause of the injury, there is no occasion for allocating partial damages.
The concept of apportioning causation must be tested on the assumption that both causes had to join to produce the injury for which damages are to be allocated. There are cases in which it may be possible to segregate the harm done by one cause from different or incremental harm done by a second cause, so as to apply proportional allocation to the additional harm only. This might be possible when a quantitative increase in a source of harm causes a corresponding increase in the injury, such as side effects from a negligent overdose of a dangerously defective drug, or if, for instance, Mrs. Sandford had broken a leg in an accident caused by the defective tire and thereafter had been burned by material negligently stored in her vehicle. Alternative solutions of such problems are discussed in Twerski, The Use and Abuse of Comparative Negligence in Products Liability, 10 Ind.L.Rev. 796, 810-823 (1977); as the litigants in today's cases present no such issues, we do not pursue them here. For the *631 same reason, we do not discuss situations in which either the defect or the injured party's negligence alone would cause the entire injury, as in a claimant's neglect properly to use faulty safety equipment which would not have functioned if used, when the parties might debate whether the negligence or the preexisting defect doomed the claimant to suffer his injuries. Once it is assumed, however, that two or more distinct causes had to occur to produce an indivisible injury, we doubt that the purpose of the proportional fault concept is to subject the combined causation to some kind of vector analysis, even in the rare case of simultaneous, physically commensurable forces. In most cases, it would be a vain exercise to search for a common physical measure for the causative effect of a product defect and of the injured party's negligent conduct.
C. Mixing "fault" with "proximate" causation. A third view considers it futile to attempt to explain what is to be compared, because it is equally illogical to compare strict liability with negligence and to quantify the relative causative effect of either when it would have caused no harm in the absence of the other. Thus Dean Twerski, in the cited article, describes the technical problems of making the comparison as a "red herring": "The short answer to the dilemma of how one can compare strict liability and negligence is that one must simply close one's eyes and accomplish the task." 10 Ind.L.Rev. 796, 806-808. The opinion in Pan-Alaska, supra, similarly questions the significance of theoretical distinctions when it states:"In any event, whether we use the term comparative fault, contributory negligence, comparative causation, or even comparative blameworthiness, we are merely beating around the semantical bush seeking to achieve an equitable method of allocating the responsibility for an injury or loss...."
565 F.2d at 1139. In part this second view rests on the assumption that rational analysis in tort cases dissolves in the collegial judgment of juries. That is probably an unwarranted generalization; ability and effort to decide in accordance with law can be expected to differ from one jury to the next with such variables as the makeup of the particular jury, with the quality of evidence and advocacy, and not least with the rationality of the legal formulations in which the court explains the jury's task to it.
*632 In any event, the assumption does not let us escape the need to state coherent rules of liability. Some tort cases are tried to the court without a jury, as Pan-Alaska, supra, illustrates. Trial judges must know on what findings an apportionment of damages depends, whether these are to be made by the judge or by a jury. Our system of appeal as well as trial predicates that jurors will conscientiously attempt to apply the law if it is explained in comprehensible terms. Sedillo v. City of Portland, 234 Or. 28, 33, 380 P.2d 115 (1963); Stage v. St. Pierre, 224 Or. 395, 401, 356 P.2d 432 (1960); Williams v. Portland Gen. Elec., 195 Or. 597, 610, 247 P.2d 494 (1952). A juror who wants to know how to treat cause and how to treat fault is entitled to an answer, whatever comes of it in a collective decision. Counsel need to know whether to address the relative gravity of the parties' fault or to seek expert testimony on the relative impact of their respective fault in causing the asserted harm. We cannot dismiss the question as a distinction without a difference.
The National Conference of Commissioners on Uniform State Laws attempted to overcome the distinction, or perhaps split the difference, in a proposed Uniform Comparative Fault Act, by calling on the factfinder, in determining the percentages of fault, to "consider both the nature of the conduct of each party at fault and the extent of the causal relation between the conduct and the damages claimed." See Wade, Products Liability and Plaintiff's Fault The Uniform Comparative Fault Act, 29 Mercer L.Rev. 373 (1978). This might add the difficulties of comparing causation to those of comparing fault if causation in fact were meant, especially since the act also calls for special findings. But the comments indicate that "the extent of the causal relation" does not mean causation in fact but what has traditionally been labeled "proximate cause." In Murray v. Fairbanks Morse, supra, also, "proximate" causation rather than factual causation turns out to be what the court means by "comparative causation."
This court has declined to phrase as issues of causation what actually are issues of legal responsibility at least since Justice *633 O'Connell's concurring opinion in Dewey v. A.F. Klaveness & Co., 233 Or. 515, 519-45, 379 P.2d 560 (1963). See Vetri, Tort Markings: Chief Justice O'Connell's Contributions to Tort Law, 56 Or.L.Rev. 235, 238-242 (1977). Causation in Oregon law refers to causation in fact, that is to say, whether someone examining the event without regard to legal consequences would conclude that the allegedly faulty conduct or condition in fact played a role in its occurrence. "`Causation in fact' is unrelated to `proximate' or `legal' cause, concepts which have been discarded by this court." McEwen v. Ortho Pharmaceutical, 270 Or. 375, 385 n. 7, 528 P.2d 522 (1974); see also Babler Bros. Inc. v. Pacific Intermountain Express Co., 244 Or. 459, 415 P.2d 735 (1966). What can be a cause in fact is a person's behavior, which is a fact, not its faulty or faultless character, which is a legal characterization. In many cases, therefore, there will be no question of causation for a factfinder to decide. Once the test of legal responsibility thus is no longer phrased as a quantum of causation, it would mark a departure if such a phrasing were reintroduced by the proportionate fault statute. An examination of the statute shows that it was not.
D. Proportionate fault under ORS 18.470. ORS 18.470, supra, by its terms applies whenever "the fault attributable to the person seeking recovery was not greater than the combined fault of the person or persons against whom recovery is sought." If there was such fault, "any damages allowed shall be diminished in the proportion to the percentage of fault attributable to the person recovering." There is no reference to causation, or to any question how much the fault of each contributed to the injury. Indeed, the reference to negligence "contributing to the injury" in former ORS 18.470 was removed in the 1975 amendment. We do not mean that the allegedly faulty conduct or condition need not have affected the event for which recovery is sought; as we have said, it must have been a cause in fact. But the statute does not call for apportioning damages by quantifying the contribution of several causes that had to coincide to produce the injury.
Rather, ORS 18.470 falls within the first of the different approaches that we have reviewed. It calls upon the factfinder to assess and quantify fault. If the plaintiff's conduct is not faultless, the assessment has two purposes: to determine whether her fault is "not greater than" that of defendants, and if it is not, then to reduce the plaintiff's recovery of damages "in the proportion to the percentage of fault attributable to" the plaintiff. The question remains against what standard this "percentage of fault" introduced by the 1975 amendment is to be measured.
The answer is implicit in the two steps found in the statute, one in the amended ORS 18.470 and the second in section 2 of the act, codified in ORS 18.480. First, if the plaintiff's behavior which was one cause of the injury is alleged to have been negligent or otherwise "fault," it is to be measured against behavior that would have been faultless under the circumstances. The factfinder is to determine the degree to which the plaintiff's behavior fell short of that norm and express this deficit as a numerical percentage, which then is applied to diminish the recoverable damages. There necessarily must be some comparable assessment of the fault attributable to defendants as a departure from the norm invoked against them (which, in products liability, will involve the magnitude of the defect rather than negligence or moral "blameworthiness") in order to determine which is greater. In this comparison, the *634 benchmark for assessing a defendant's fault for marketing a product which is dangerously defective in design, manufacture, or warning is what the product should have been without the defect. The benchmark for the injured claimant's fault is conduct which would not be unlawful or careless in any relevant respect. This corresponds to views expressed by the Supreme Judicial Court of Maine:"[A]pportionment is on the basis of fault or blame. This involves a comparison of the culpability of the parties, meaning by culpability not moral blame but the degree of departure from the standard of a reasonable man.... [C]omparison is invited between degrees of fault which may range from trivial inadvertence to the grossest recklessness.... In judging the conduct of an actor it should be considered complete carefulness is at one end, a deliberate intention to bring about the result is at the other. Negligence ranges from the least blameworthy type, namely, inadvertence and negligent errors of judgment up to a state where knowledge or more complete knowledge supervenes and the negligence of obstinacy, self-righteousness or reckless is reached. The factfinder must be told then under our statute, it should give consideration to the relative blameworthiness of the causative fault of the claimant and of the defendant."
Wing v. Morse, 300 A.2d 491, 500 (Me. 1973). Quoting this excerpt, one writer suggests:"One method of conceptualizing the share of the negligence [or "fault"] attributable to each party is to imagine a `fault line,' with the absence of fault at one end having a value of zero and a deliberate wrongdoing at the other having a value of ten. The fact finder would then establish where on this line the conduct of each party falls."
Pearson, Apportionment of Losses Under Comparative Fault Laws An Analysis of the Alternatives, 40 La.L.Rev. 346, 348-9 (1980). Although Professor Pearson acknowledges that this "fault line" method cannot be as precise as it sounds, he suggests that "it does provide a means of visualizing the fact finder's task, which perhaps could be put into a useful form." Id.
If the claimant's fault in this sense is greater than the fault of defendants, recovery is barred. Thereafter, ORS 18.470 standing alone does not seem to assign any further role to the magnitude of defendants' fault in calculating the percentage of plaintiff's damages that she may recover.*635 Section 2 of the 1975 act, however, added directions for the second step. ORS 18.480 provides:"(1) When requested by any party the trier of fact shall answer special questions indicating: "(a) The amount of damages to which a party seeking recovery would be entitled, assuming that party not to be at fault; "(b) The degree of each party's fault expressed as a percentage of the total fault attributable to all parties represented in the action. "(2) A jury shall be informed of the legal effect of its answer to the questions listed in subsection (1) of this section."
Accordingly, after determining whether and how far each party's conduct was at fault, measured against the norm governing that party's conduct, these respective degrees of fault are to be converted into a percentage which will be applied to the plaintiff's total damages to determine his actual recovery.
To summarize: When an injured claimant's misconduct is a cause in fact of the injury, it can defeat a products liability claim if the claimant's fault is "greater than" the defendants' combined fault involved in marketing the defective product. If it is not greater, plaintiff's fault proportionately reduces her recoverable damages. "Fault" includes contributory negligence except for such unobservant, inattentive, ignorant, or awkward failure of the injured party to discover the defect or to guard against it as is taken into account in finding the particular product dangerously defective. Accordingly, we reject plaintiff's assertion that ordinary negligence on her part would not be an offset or possible defense against her products liability claim.IV. The allegations of plaintiff's negligence.
In view of the foregoing discussion, applicable also to Wilson v. B.F. Goodrich, 292 Or. 626, 642 P.2d 644 (1982), the trial court in principle did not err in submitting plaintiff's alleged negligence to the jury for consideration in denying or reducing plaintiff's damages. The parties dispute, however, whether there was evidence to support the specifications of negligence alleged by defendants.
The trial court submitted to the jury allegations that plaintiff was negligent in operating the pickup and camper fully loaded when she was not familiar with doing so, in failing to keep proper control, and in operating at an excessive rate of speed under the conditions. The court struck another allegation by defendants that plaintiff was negligent in operating the vehicle with three full gas tanks and six additional five-gallon cans of gas inside the camper.
Plaintiff asserted on appeal that there was insufficient evidence on which to submit to the jury those allegations which were submitted, but on review in this court plaintiff waived that objection if this court found evidence sufficient to support any one of the allegations. Plaintiff's major reliance was on the legal argument already discussed that plaintiff's alleged negligence was not the kind that would reduce or deny her damages in a products liability case.
*636 We find sufficient evidence in the record to submit to the jury the issue of plaintiff's familiarity with the operating characteristics of the loaded pickup and camper at the time of the accident. Shortly before that day a power steering unit had been installed in the pickup. Plaintiff had driven the truck with power steering only once before that day, when it had not been loaded with equipment for the camping trip. At the time of the accident, the vehicle began swaying and weaving on the highway before it eventually rolled over and slid on the pavement. It is not impossible that plaintiff's attempts to control the heavily loaded vehicle when the tire failed were adversely affected by her unfamiliarity with the behavior of the power steering system. A jury might so conclude under one of the first two specifications mentioned above.
Defendants contend that the court should have submitted their allegation that plaintiff caused or contributed to her own injuries by operating the vehicle with its numerous extra containers of gasoline. The parties argued this point, in the light of the position earlier taken by the Court of Appeals in Holdsclaw v. Warren & Brewster, supra, largely on the legal issue whether this allegation stated the kind of voluntary assumption of an obvious hazard that would count against the plaintiff's recovery in a products liability claim. Carrying extra gasoline cans is not, of course, a hazard of an unexpectedly defective tire as distinct from anything else that might cause some of the gasoline to escape and ignite, and the trial court did not regard it as an appropriate invocation of the defense left open by Holdsclaw. Although we hold that ordinary negligence can suffice as an offset or defense in a products liability case, it was not error to reject the allegation on the basis on which it was pleaded and argued to the trial court. These rulings are not grounds for a new trial.V. The jury poll.
The Court of Appeals reversed the judgment entered on the jury verdict because it found that the manner in which the jury was polled did not adequately assure that three-fourths of the jury had concurred in all parts of the verdict. ORS 17.355.
The jury had been given a verdict form which called upon it to answer four separate questions. After seven and one-half hours of deliberation, the jury reported a deadlock of eight votes to four. The court instructed it to continue trying. After several more hours, the jury sent word that it had a question, which it was told to put in writing. Instead of the question, however, the jury reported that it had reached a verdict and accordingly was recalled to the courtroom. After the clerk read the four questions and the answers on the verdict form, the following occurred:*637 "THE COURT: Mrs. Horst, was your verdict unanimous? "MRS. HORST: It was nine to three. "THE COURT: All right, we are going to poll the jury and each of you will be asked this question: Is this your verdict. And your only response to that question should be either `yes', if this was your verdict or `no', if this was not your verdict. Any questions about the polling?"
When the clerk polled the jury, all twelve of the jurors answered "yes." The court announced that it would receive the verdict and discharge the jury. Counsel for defendants requested that the jury first be polled again as to each of the questions posed in the verdict form, expressing concern that the difference between the poll and the previously reported vote showed confusion on the part of the jurors. This request was denied.
This court has held, and the parties do not dispute, that the same jurors must constitute the three-fourths majority that finds every separate element required for the verdict. Munger v. S.I.A.C., 243 Or. 419, 414 P.2d 328 (1966); Schultz v. Monterey, 232 Or. 421, 375 P.2d 829 (1962); Clark v. Strain, 212 Or. 357, 319 P.2d 940 (1958). It is proper so to instruct the jury. See Aronson v. Fagan, 278 Or. 135, 562 P.2d 974 (1977). In that case, the trial court had done so, and when polling the jury after a nonunanimous verdict, the court again reminded the jurors: "Of course, those of you that say `yes' have to agree with each of the answers in the several questions." Under those circumstances, this court held that there was no prejudice in failing also to poll each juror on each separate question. 278 Or. at 138. When a trial court failed to give the instruction, on the other hand, the error was said to have been waived because the appellant had not taken advantage of an opportunity to have the jury polled on each separate issue. Whelchel v. Strangways, 275 Or. 297, 550 P.2d 1228 (1976).
The Court of Appeals concluded that the statutory right to have the jury polled is designed to demonstrate that the announced result represents a valid verdict and therefore includes the right to have the jurors polled whether they concur in each part of the verdict. We agree. It remains to decide whether this requires reversal of the present judgment, as the Court of Appeals held.
Plaintiff relies on prior decisions of this court that have imposed high evidentiary demands on a party seeking to impeach a jury verdict. See, e.g., Blanton v. Union Pacific Railroad Co., 289 Or. 617, 628, 616 P.2d 477 (1980) (post-trial letter from juror that verdict was an improper quotient verdict). Blanton cited Carson v. Brauer, 234 Or. 333, 382 P.2d 79 (1963) (post-trial affidavits concerning comments among jurors), State v. Gardner, 230 Or. 569, 371 P.2d 558 (1962) (juror's comments based on acquaintance with defendant), and Schmitz v. Yant, 242 Or. 308, 409 P.2d 346 (1965) (prospective juror's comments to other jurors). These decisions are distinguishable insofar as each involved the use of post-trial affidavits or other evidence to show that a verdict was tainted by misconduct. In the present case, we are concerned with the effect of omitting a procedure which is designed to test the numerical validity of a verdict at the time it is rendered.
As the Court of Appeals noted, the jurors earlier had been divided eight to four after more than seven hours of deliberation, and reported that they still had a question just before they returned a verdict. It is not inconceivable that the difficulty lay in finding nine jurors to agree to each of the four answers, and that it may have been met by finding a different ninth vote for one or more of the answers, which would not be a valid verdict. Under the circumstances, the court held that it was impossible to say that the failure correctly to poll the divided jury was harmless error. We cannot disagree *638 with that conclusion. The decision of the Court of Appeals is affirmed.
PETERSON, Justice, concurring.
I concur with the opinion of the court in all respects except one. I disassociate myself from part III of the opinion, not because I necessarily disagree with what is stated therein, but because that part of the opinion is totally unnecessary to the decision of this case, involves questions not raised or considered in either the trial court or the Court of Appeals and not argued or discussed by the parties, and adopts significant rules of law on important controversial questions without the issues being presented, contended for, briefed, or argued.
It is clear that the parties, from the beginning of the case, disputed whether the contributory negligence of plaintiff would bar or reduce a recovery when the plaintiff's claim is based on a strict liability theory. But there was no issue in the trial court relating to the quantification of fault, the comparison or apportionment of fault, or the manner by which the plaintiff's comparative fault would be calculated to bar or reduce recovery.
Although the plaintiff's attorney took exception to the giving of any comparative negligence instructions, no other exceptions to the court's comparative fault instructions were taken. On appeal, the plaintiff claimed that the court erred in instructing the jury that the plaintiff's comparative negligence could bar or reduce her recovery. This was one of the issues tendered to the Court of Appeals for decision, and this issue was decided by the Court of Appeals in the plaintiff's favor. There were no other claims of error addressing liability.
The defendants, in their petition for review, claimed only (1) that the Court of Appeals erred in failing to hold that all forms of contributory negligence "can be considered for comparative purposes in a strict liability action" and (2) that the Court of Appeals erred in "* * * ruling that the jury could not consider the fault of the plaintiff in voluntarily encountering an obvious risk or hazard * * *." The court's opinion decides all of the questions presented in the petitions for review. In addition, in part III of the opinion the court adopts rules relating to (1) what conduct determines fault; (2) against what standard the conduct is compared to determine the amount of a party's fault; and (3) the manner by which the "* * * respective degrees of fault are to be converted into a percentage which will be applied to the plaintiff's total damages to determine his actual recovery."
The question whether the determination of fault is to be made (1) by the extent to which fault caused the injury, (2) by comparing "fault," or (3) by making both comparisons, is a significant, provocative, controversial, important question. I don't *639 suggest that we back away from provocative and controversial questions. But we should not adopt such significant rules of law when no facts are before us for decision, where the issue has not been presented for decision, when the issue has not been raised by any party, and when a ruling on the issue is not necessary to the disposition of the case.
I am sensitive to the fact that these are important questions. But I would rather make all decisions when the issue is properly before us, rather than in the abstract, without argument from anyone, and without facts to look to in making the decision. All questions, especially important questions, are best decided when the parties raise them, brief them, and argue them. There may be significant reasons not revealed by our own research and consideration which point toward a different conclusion. Even though we are a court of review, (Rule of Appellate Procedure 10.05), nonetheless our function is to decide cases that come before us, not to muse about "what the rule of law should be if."
The advent of strict liability and comparative negligence has created difficult, provocative, challenging and important questions. In the past generation, we have decided a host of cases involving such questions. But to the best of my knowledge, since the enactment of ORS 18.470 in 1971, no party has ever claimed error by reason of the instructions of the court relating to the manner in which "fault" is to be determined or apportioned, or the manner in which the plaintiff's damages are to be diminished by reason of such fault. Obviously, the development of new rules of law is necessary if courts are to be responsive to societal needs. But rules of law are best forged on the anvil of actual controversy rather than by taking a massive bite out of the carcass of a field of law and spitting out a rule of law which, in the abstract, tastes good. We have repeatedly refused to give advisory opinions, even though the parties have asked for them. We should not gratuitously render advisory or academic opinions which are not sought. See Oregon Medical Association v. Rawls, 281 Or. 293, 296-300, 574 P.2d 1103 (1978); Oregon Medical Assn. v. Rawls, 276 Or. 1101, 1108, 557 P.2d 664 (1977); Smith v. Smith, 209 Or. 96, 98, 304 P.2d 421 (1956).
I have no quarrel with concurring opinions which point up problems in a given area. Such concurring opinions perform a beneficial function and often lead to beneficial results. See, for example, the concurring opinion of Justice Linde in State v. Stroup, 290 Or. 185, 620 P.2d 1359 (1980), which flagged an issue which is even now being considered by this court in State v. Buttrey, 54 Or. App. 40, 642 P.2d 704, rev. allowed 292 Or. 108 (1981); the concurring opinion of Chief Justice Denecke in State v. *640 Wolfe, 273 Or. 518, 528, 542 P.2d 482 (1975), which pointed up a problem which was recently considered by this court in State v. Douglas, 292 Or. 516, 641 P.2d 561 (1982); and the opinion of Justice Lent in Hendrix v. McKee, 281 Or. 123, 125, 575 P.2d 134 (1978), which led to our decision in Falk v. Amsberry, 290 Or. 839, 626 P.2d 362 (1981).
A study of the articles and cases cited in the majority opinion and in this opinion compels the conclusion that the issues with which part III is concerned are difficult, complex, controversial questions which are far from being settled with any substantial uniformity. On the question of allocation of fault under Connecticut's then new comparative negligence law, Professor Fleming James wrote:"What is to be compared. A perennial question under comparative negligence statutes is whether apportionment is to be made by comparing fault, or by comparing the extent to which fault contributed to the injury, or by making both comparisons. The statutory language suggests that only faults are to be compared: `damages ... shall be diminished in the proportion of the percentage of negligence attributable to the person recovering.' And Prosser says bluntly, that `once causation is found, the apportionment must be made on the basis of comparative fault, rather than comparative contribution.' "Courts which have dealt with comparative negligence statutes have not, however, embraced the appealing simplicity of this view. The Wisconsin statute is worded very much like ours. In Kohler v. Dumke defendant urged a view diametrically opposite to Prosser's, that if plaintiff were found negligent `then in resolving the comparative negligence issue only the element of causation should be considered.' The court disagreed, saying, `We deem it clear that the word "negligence" in the comparative negligence statute ... means causal negligence ... Therefore, in comparing the negligence of two or more persons, the jury is to consider both the elements of negligence and causation.' The Mississippi statute, which is worded like the Wisconsin statute in this respect, has been construed the same way. The Maine statute, patterned after the British, is somewhat differently worded. Under both of these comparison is made both of fault and of causal contribution. Professor Fleming, with an extensive background in the law of the British Common-wealth, takes more or less the same view. The weight of authority, then, inclines heavily to this view and it seems likely that Connecticut courts will follow it." (Footnotes omitted; emphasis in original.)
On the question of how fault is to be determined the answer is anything but clear, as is seen by these commentators."On these foundations, we may proceed to examine the theoretical concept of `degrees of fault.' Immediately, we encounter an anomaly, with which we will be required to struggle throughout our study. `Fault' is not a finite object. It is, rather, an evaluative judgment about the quality of conduct or performance. As such, it is not a judgment which proceeds out of sensory observation or measurement in the same direct sense that quantitative evaluations or conclusions do. A judgment of fault, in other words, is only mediately supported by objective evidence; immediately and directly, it is a subjective legal or ethical pronouncement of responsibility for wrongdoing. "* * * "It is out of a candid recognition of the essential subjectivity of these judgments that `the rule of law' attempts, by book and by instruction, to superimpose its own standards and definitions on subjective conceptions of fault and nonfault, and solemnly charges its judges and jurors to adopt and apply those standards *641 and definitions in the process of litigation. In this vein, we devise careful legal definitions of such concepts as `negligence' and `cause,' identifying specific standards for determining their presence or absence. "If, for lack of any alternative, we are compelled to accept the somewhat naive notion that this process of superimposition really works to unseat the studied or instinctive preconceptions of the individuals concerned, it is sheer fantasy to assume that subjective standards of evaluation will not continue to govern the matter where no rational or objective legal standard or definition is possible, or is even suggested. Such is the case with respect to the concept of `degrees of causative negligence.'" (Emphasis in original.)
On cause-in-fact apportionment, Professor Twerski writes:"It is time to consider the use of the comparative fault doctrine to include within its sweep not only fault and proximate cause but cause-in-fact as well. In my opinion, the inevitable effect of instructing a jury that proximate cause is an item for comparison will be that cause-in-fact will be factored into the jury's consideration. * * * "As a statement of fact and pure logic, it is clear that cause-in-fact is not subject to apportionment. But in our saner moments, we ought to be ready to admit that cause-in-fact is one of the most intractable items to prove in a law suit. * * "* * *. "In reality I believe that this will occur when cases are turned over to juries on a comparative fault instruction. Jurors, not being schooled in the separate pigeon holes created by tort teachers, are still naive enough to believe that an accident does not take place in five stages. Duty, standard of care, cause-in-fact, proximate cause and damages are supposed to be analytical aids. They are not descriptive of the process of accomplishing a tort. Thus, juries will have to be excused if they view the entire injury event as a unitary whole and factor the probability of causation together with fault in arriving at a percentage apportionment. * *." (Footnotes omitted.)
The Uniform Comparative Fault Act recognizes the difficulty in determining fault. Section 2(b) of the Uniform Comparative Fault Act (12 ULA 37, 1982 Pocket) provides:"(2)(b) In determining the percentages of fault, the trier of fact shall consider both the nature of the conduct of each party at fault and the extent of the causal relation between the conduct and the damages claimed."
Although I may agree with the holding of part III of the opinion if and when the questions are presented, I have serious reservations as to the practical implications of the court's holding. To implement the holding of part III of the court's opinion lawyers must formulate requested instructions and trial judges must give instructions to the jury concerning how fault is to be determined, how fault is to be apportioned and how plaintiff's damages are to be diminished by reason of the plaintiff's fault. I have no doubt that this will be done, for now it must be done, but I have reservations whether the desired end product a verdict based upon objectivity and fairness and in accordance with the law is more likely to be achieved than is now the case under current Oregon practice. See Oregon Uniform Jury Instructions 11.50-11.60. To accommodate the rules set forth in Part III of the court's opinion among the instructions that a trial judge will have to give upon proper request are these:
1. What fault is.
*642 2. The standard against which a party's fault is to be compared in determining the party's percentage of fault.
3. That although "[b]oth the defect and the plaintiff's fault must in fact be causes of one injury before a question of apportionment of fault arises" (at 630), once the jury finds causation in fact to exist they are not to consider the causal relationship between the fault and the injury in apportioning the party's fault. Rather, their apportionment of fault must be made by comparing the party's fault against "* * * behavior that would have been faultless under the circumstances * * *."
4. How the jury is to calculate the degree of each party's fault against the norm.
Comment: The majority would require that the initial determination of fault be made against a standard of behavior "that would have been faultless under the circumstances" or by comparing the product to "what the product should have been without the defect." The result could be expressed numerically, by a percentage, or otherwise. The number is to reflect the degree by which or to which the behavior falls short of the norm, and must then be expressed in terms of a "* * * deficit as a numerical percentage, which then is applied to diminish the recoverable damages." Opinion at 633.
5. How the jury should convert the party's percentage of fault into "* * * a percentage of the total fault attributable to all parties represented in the action," as required by ORS 18.480.
Comment: Keep in mind that ORS 18.480 requires that, upon request, the jury "* * * shall answer special questions indicating: * * * (b) The degree of each party's fault expressed as a percentage of the total fault attributable to all parties represented in the action" (Emphasis added). The jury will have to convert the percentage by which the party's conduct "fell short of [the] norm" into "a percentage of the total fault attributable to all parties represented in the action," as required by ORS 18.480(1)(b). If the jury decided that a plaintiff's fault, when tested against the norm of faultless conduct, were 20 percent, and that a defendant's fault, when compared against the appropriate norm, were 25 percent, the jury must then convert those percentages into percentages "of the total fault," as required by ORS 18.480(1)(b). The result: Plaintiff's percentage of fault would be 44.44 percent (20/45); the defendant's percentage of fault would be 55.56 percent (25/45), and the plaintiff's recovery would be reduced not 20 percent, but 44.44 percent. If there were three parties, and the respective percentages of fault were plaintiff, 20 percent; defendant No. 1, 25 percent; defendant No. 2, 30 percent, the conversion into percentages "of the total fault attributable to all parties represented in the action" would be: Plaintiff, 26.67 percent (20/75); defendant No. 1, 33.33 percent (25/75); and defendant No. 2, 40 percent (30/75), and the plaintiff's recovery would be reduced by 26.67 percent.
6. Finally, the jury is required to "* * * be informed of the legal effect of its answer to the questions * * *." ORS 18.480(2).
The majority opinion itself reflects the potential for confusion which may arise in applying the rules set forth in the opinion. Footnote 18 states:"* * * This approach would not necessarily deny all damages even to a plaintiff guilty of extreme misconduct (say `80 percent' below the `fault line') if the extent that defendant fell short of the norm is even greater; it would simply reduce plaintiff's recovery to 20 percent of her damages."
I gather that the quoted statement applies to the theory discussed in 43 Mo.L.Rev. 431, 449-450, for the statement cannot be correct as applied to ORS 18.470 and ORS 18.480. If plaintiff's misconduct were 80 percent, before there could be any recovery, the fault of the defendant(s) must equal or exceed that of the plaintiff. Thus, if there were but one defendant, whose fault was also 80 percent, the plaintiff's recoverable damages would be 50 percent of the total damages, not 20 percent. If the fault of *643 the defendant were 90 percent, plaintiff's recoverable damages would be reduced by 47.06 percent (80/170).
The mathematics can be difficult. Regarding the mathematical calculations, David L. Nixon wrote:"Entrusting the entire process of dollar damages apportionment to the jury under general verdict procedures will strike some as an act of faith bordering on irresponsibility. The express prohibition of special interrogatories was not contained in the bill as drafted when first introduced, although the bill did require that `the jury ... diminish the damages'. As the hearings and discussions on the subject of the comparative negligence bill progressed through the Legislative Session and as knowledge was gained of Maine's experience with its 1965 statute, the realization grew that the rough and basic justice of unfettered jury deliberation was probably preferable (and at least worth a good try) as an alternative to the horrendous mathematical processes described by opponents of the legislation as necessarily a part of the jury's function under special verdict statutes. Most of those involved in the jury trial process, it is submitted, would agree on reflection that New Hampshire juries are populated in the main by neither misers nor spendthrifts. Others, with much in the way of research and experience to draw from, agree on the fundamental fairness and good sense of the average juror." (Footnotes omitted.)
The practices which have been followed in Oregon trial courts (which generally utilize the Uniform Jury Instructions) appear to me to have been generally satisfactory. Whether or not I am correct, there is no reason for this court to unilaterally impose far-reaching rules of procedure and substantive law on the citizenry without input from anyone.
As a young lawyer, it took me months to understand and apply the "Lamb-Weston rule," as set forth in Lamb-Weston et al v. Ore. Auto. Ins. Co., 219 Or. 110, 137-138, 341 P.2d 110, 346 P.2d 643, 76 A.L.R.2d 485 (1959), which states the principle that when there are two or more policies of valid and collectible insurance which are applicable to a loss, the total loss will be apportioned among the insurers in the ratio which the limits of each policy bear to the total available coverage. I fear that many juries will find it difficult if not impossible to understand and apply the similar rules set forth in part III of the opinion.
The doctrine of comparative negligence intends to avoid the harsh result of the common law contributory negligence rule that any negligence by the plaintiff, however small, barred recovery. Comparative fault statutes were designed to temper that rule by either granting plaintiff recovery against a negligent defendant whatever the degree of the plaintiff's fault (pure comparative fault) or by permitting the plaintiff to recover from negligent defendants if the plaintiff's fault was "not greater than" or was less than the defendant's or the combined fault of multiple defendants. The superimposed declaration under statutes similar to Oregon's comparative fault statute, is that the plaintiff's right to recover turns on whether the plaintiff's fault was not greater than or less than the fault of the person against whom claim is made. Inherent in the doctrine is the comparison of fault the plaintiff's fault is compared to the defendant's. That premise leads me to conclude that it is likely that the framers of comparative fault legislation contemplated that the fault of a party be determined by directly comparing his or her fault against the fault of other party or parties against whom claims were made, rather than by the injection of an intermediate step whereby fault is determined by comparing conduct against a separate standard and then comparing the numerical results to determine who wins or loses and by how much. I am not convinced that the drafters of ORS 18.470 intended this type of comparison.
*644 The advent of strict liability has made it more difficult to compare fault based on negligence against fault based on strict liability. But jurors have been equal to that task, possibly without benefit of rational definition or standard, and until the issue arises, I would do nothing and say nothing.
Part III of the opinion of this court is unnecessary to the decision, does not involve the correction of any error, does not involve a question likely to arise on remand (except for our gratuitous reference to the matter), and involves issues which have concerned the bench and bar of this state, until now, very little or not at all. On a comparative fault basis, our fault is a 99 for publishing part III of the opinion.
DENECKE, C.J., joins in this opinion.NOTES
[*] Tongue, J., retired February 7, 1982.
 The questions were:
"(1) What considerations determine whether contributory negligence may be used for comparison in apportioning damages when plaintiff is proceeding on the theory of strict liability in tort?
"(2) What type of contributory negligence qualifies as comparative fault as a defense or partial defense to a plaintiff's strict liability claim, both generally and in this case? Why? Cf. Baccelleri v. Hyster Company, 287 Or. 3, 12-13, 597 P.2d 351 (1979).
"(3) If the court were to hold that ORS 18.470 calls for a comparison in a products liability case between the `fault' of marketing the defective product and the `fault' of plaintiff's negligence, what is the jury or trial court called on to compare? It is the relative `magnitude' of each fault, i.e., the degree to which the allegedly defective product departed from the norm and the degree to which plaintiff's conduct departed from that of a reasonable person under the circumstances? Or is it the degree to which the defect and the plaintiff's negligence, respectively, contributed to the probability that the injuries would occur?
We particularly draw attention to the third question because the concurring opinion states that there was no opportunity to argue the question of the method of apportionment.
 ORS 18.470 (1971):
"Section 1. Contributory negligence, including assumption of the risk, shall not bar recovery in an action by any person or his legal representative to recover damages for negligence resulting in death or injury to person or property if such negligence contributing to the injury was not as great as the negligence of the person against whom recovery is sought, but any damages allowed shall be diminished in the proportion to the amount of such negligence attributable to the person recovering."
 defendant must show, first, that the plaintiff himself actually knew and appreciated the particular risk or danger created by the defect; second, that plaintiff voluntarily encountered the risk while realizing the danger; and, third, that plaintiff's decision to voluntarily encounter the known risk was unreasonable...."
274 Or. at 403, 547 P.2d 132.
 ORS 18.475:
"(1) The doctrine of last clear chance is abolished.
"(2) The doctrine of implied assumption of the risk is abolished."
 We need not now speculate on the legislative policy when a plaintiff who is not without fault in her own injury sues a defendant on a theory of absolute liability without fault.
 For instance, ORS 18.470 now literally states that when the plaintiff's fault (of whatever kind) is no greater than the defendants' fault (of whatever kind), then the plaintiff's contributory negligence shall not bar her recovery. While one may infer that recovery remains barred when a plaintiff's contributory negligence exceeds defendants' fault, the words of the statute do not expressly negate proportional reduction of damages when a plaintiff's fault other than negligence exceeds the defendants' fault, or when a plaintiff is both negligent and otherwise at fault, as in unlawfully acquiring the product or unlawfully placing himself in the position to be injured.
 Representative Frohnmayer apparently meant a proposed amendment that was reported by the House Committee on Judiciary as section 4 of A Engrossed Senate Bill 797 and became section 4 of chapter 599.
 Aiken, Proportioning Comparative Negligence Problem of Theory and Special Verdict Formulation, 53 Marq.L.Rev. 293, 295 (1970):
"In law [unlike science] ... we find objective evidentiary support only for our findings of what has happened, or of what was done or not done. But the superimposed declaration, that the conduct so found is blameworthy or blameless, is capable of accurate comparative evaluation only in the sense that it can be declared, somewhat analogously, to be more or less blameworthy than other blameworthy conduct (actual or hypothetical), which may be adopted as an ad hoc standard for comparison. Qualitative thought, in short, is not inherently susceptible of supportable comparison except, at most, in terms of good-better-best or bad-worse-worst. To assert a judgment that one instance of wrongdoing represents a precise degree of mathematical `worseness,' even as compared to another, requires the presence of a calibrated scale of `badness,' which simply does not exist in reality or in our conceptual framework."
 See, e.g., Fischer, Products Liability Applicability of Comparative Negligence, 43 Mo.L. Rev. 431 (1978); Levine, Strict Products Liability and Comparative Negligence: The Collision of Fault and No-Fault, 14 San Diego L.Rev. 337 (1978).
 Compare these views:
"Even those who would sacrifice functional to purely doctrinal considerations and argue that `oil and water can't mix,' might be persuaded in this instance by the thought that products liability as has often been, half apologetically, emphasized is not absolute but is based on the social fault of marketing defective products. A matrix for apportionment is thus available."
Fleming, The Supreme Court of California 1974-1975 Foreword: Comparative Negligence at Last By Judicial Choice, 64 Calif.L.Rev. 239, 270 (1976).
"Because of the desirability of applying comparative negligence to strict liability, a number of judges and writers have urged that strict liability does not involve `fault' that can be compared with the plaintiff's contributory negligence. This is either the `social fault' involved in marketing defective products or the `legal fault' arising from a breach of duty to market defect-free products.
"This approach does not solve the underlying problem of the lack of a workable basis of comparison. The word `fault' can be redefined to include innocent conduct as well as culpable conduct, but this merely begs the question. `Social fault' in marketing defective products still has nothing in common with the type of specific personal culpability required for contributory negligence. The concepts cannot be compared rationally."
Fischer, supra, 43 Mo.L.Rev. 431, 442. Professor Fischer's criticism continues with the illustration of a defendant wholesaler who distributes the defective product in a closed container and whose "fault" is hard to place on any "spectrum of blameworthiness."
 See Thibault v. Sears, Roebuck & Co., 118 N.H. 802, 395 A.2d 843, 850 (1978):
"[T]he trial court ... should instruct the jury that it is to compare the causal effect of the defect in the product or design with the affirmative defense of the misconduct of the plaintiff ... and reduce the amount of damages by the percentage that the plaintiff's misconduct contributed to cause his loss or injury as long as it is not greater than fifty percent."
 Professor Schwartz, supra, offers the hypothetical illustration of a collision between a motorcyclist and a large truck, in which it can be scientifically determined from the weight, speed, and angle of impact that the momentum of the truck contributed 95 percent of the force that injured the motorcyclist. Assuming the motorcyclist was intoxicated and speeding, should he nevertheless recover 95 percent of his damages under a comparative fault statute? If the truckdriver, as the injured party, was far less culpable, would he be precluded from recovery by a 50-percent "comparative causation" bar? See also Carestia, The Interaction of Comparative Negligence and Strict Products Liability Where Are We? 47 Ins. Counsel J. 53, 67 (1980).
The same criticism can be made in a case of strict product liability instead of negligence.
 He also offers the suggestion that "comparative causation" might really be a way to compare the relative probabilities that the injury was in fact caused by the fault charged against each party:
"The normal standard of proof on causation is that plaintiff must establish the causal connection by the balance of probabilities ... If, however, juries are presented with a mechanism to allow them to take into account the likelihood, at a percentage basis, that the defendant's fault caused the harm, then causation could be easily compromised and the issue removed from its all-or-nothing shibboleth. Comparative fault presents to juries the mechanism for compromising difficult cause-in-fact questions." (Footnotes omitted.)

 See, e.g., Twerski, The Many Facts of Misuse: An Inquiry Into the Emerging Doctrine of Comparative Causation, 29 Mercer L.Rev. 403, 414 (1978); compare Aiken, supra note 8, 53 Marq.L.Rev. 293, 316. Apparently legislators sometimes prefer to abandon the effort to articulate a method of allocating responsibility for injuries in favor of "the rough and basic justice of jury deliberation" and "the fundamental fairness and good sense of the average juror," see Nixon, The Actual "Legislative Intent" Behind New Hampshire's Comparative Negligence Statute, 12 NHBJ 17, 30 (1969), in effect making no law to govern the decision of an individual factfinder, whether juror or judge.
 The Act and accompanying comments is printed in 29 Mercer L.Rev. at 392-401. Section 2 would provide in part:
"(a) In all actions involving fault of more than one party to the action, including third-party defendants and persons who have been released under Section 6, the court, unless otherwise agreed by all parties, shall instruct the jury to answer special interrogatories or, if there is no jury, shall make findings, indicating:
"(1) the amount of damages each claimant would be entitled to recover if contributory fault is disregarded; and
"(2) the percentage of the total fault of all of the parties to each claim that is allocated to each claimant, defendant, third-party defendant, and person who has been released from liability under Section 6. For this purpose the court may determine that two or more persons are to be treated as a single party.
"(b) In determining the percentages of fault, the trier of fact shall consider both the nature of the conduct of each party at fault and the extent of the causal relation between the conduct and the damages claimed."
29 Mercer L.Rev. at 394.
The comment to section 2 states:
"In determining the relative fault of the parties, the factfinder will also give consideration to the relative closeness of the causal relationship of the negligent conduct of the defendants and the harm to the plaintiff. Degrees of fault and proximity of causation are inextricably mixed, as a study of last clear chance indicates, and that common law doctrine has been absorbed in this Act. This position has been followed under statutes making no specific provision for it."
29 Mercer L.Rev. at 395.
 relevant causation inquiry in a strict products liability suit should be whether the product defect `caused-in-fact' some or all of the injury and whether the plaintiff's faulty conduct `caused-in-fact' all or some of the injury. If the answer to both these questions is affirmative, the issue of proximate cause becomes relevant ... Under a comparative causation approach, once the jury has determined that the product defect caused the injury, the defendant is strictly liable for the harm caused by his defective product. The jury, however, would be instructed to reduce the award of damages `in proportion to the plaintiff's contribution to his own loss or injury.' Pan-Alaska Fisheries, supra, 565 F.2d at 1139."
Murray v. Fairbanks Morse, 610 F.2d at 160.
 Professor Fischer, supra note 10, collects from a number of sources these factors that a factfinder might consider in assessing the relative fault of the parties:
"1. The magnitude of the harm threatened by the conduct; the more dangerous the conduct, the more culpable the party is likely to be.
"2. The extent to which the harm was foreseeable. In this regard inadvertent conduct is less culpable than the deliberate creation of a risk of harm. The diminished capacity of the party or the presence of an emergency are also factors which lessen culpability.
"3. Balanced against the foregoing factors is the value of the interest the party was protecting by his conduct. Less culpability is involved in taking an unreasonable risk to achieve a worthy objective than to achieve an unworthy one. However, this factor must be considered in light of the alternative means available to the party to protect his interests."

"In comparing the fault of strict liability with plaintiff's negligence, the trier of fact may find it helpful to have information on matters such as the seriousness of the injury likely to be incurred if the product is dangerously defective and the number of people likely to be affected, the feasibility of possible safety devices that might have prevented the injury, the effectiveness of possible warnings or instructions, and the nature of the inspection system. On the matter of inspecting the products as they come off the assembly line, for example, even though a system of spot-checking may be regarded as sufficiently thorough to keep the manufacturing process from being characterized as negligent, if the particular product was dangerously defective, the nature of the spot-checking would still be relevant in determining the respective percentages of fault."
29 Mercer L.Rev. at 378. Other measures of culpability enter when the "fault" is intentional misconduct or a statutory violation.
 Compare Fischer, supra n. 9, 43 Mo.L.Rev. 431, 449-450:
"The method of apportioning damages in accordance with the plaintiff's fault is to compare the plaintiff's conduct with how he should have conducted himself (the objective standard of the reasonable man) and reduce his recovery according to the extent of fault ... A plaintiff who is guilty of mere inadvertence is only moderately at fault and should have his damages reduced to a moderate extent. A plaintiff who knowingly encounters a serious risk for no good reason is greatly at fault and should have his damages reduced to a very great extent...."
This approach would not necessarily deny all damages even to a plaintiff guilty of extreme misconduct (say "80 percent" below the "fault line") if the extent that defendant fell short of the norm is even greater; it would simply reduce plaintiffs recovery to 20 percent of her damages.
 For example, if on Professor Pearson's scale of fault from 0 to 10 (zero being faultless conduct) a product defect were rated at 3 and an injured claimant's negligence at 2, ORS 18.480 would require this to be converted to percentages of 60 and 40 percent. The same result is ordained if the defectiveness of the product rises to a level of "6" and plaintiff's fault to "4". The problem is not changed if the degree to which the fault of each departs from the norm is first stated as a percentage, e.g., a 60 percent product defect and a 20 percent shortfall of due care; ORS 18.480 requires this to be converted into 75 percent and 25 percent respectively. Even when a jury is instructed that the fractions ultimately must add to 100 percent, as it was in this case, the important point is that the "fault" of each party must be measured against what would be faultless conduct (or a defect-free product) for that party; a user's negligence cannot be "measured" directly against the defectiveness of a product.
 The attempt to plead the defense within the terms of Holdsclaw is understandable but did not prevent pressing an argument based on ordinary negligence.
"One necessary consequence [of this Court's discretionary review] is that counsel will sometimes have to impose on the patience of trial courts to renew a contention that has previously been rejected by the Court of Appeals, even though this court denied review in the earlier case or cases, so that the contention is not waived and the issue foreclosed from review. An issue that may appear to be settled by one or more opinions of the Court of Appeals may in fact not be settled when a later petition presenting the issue demonstrates that it deserves review in this court."
1000 Friends of Oregon v. Bd. of Co. Comm., 284 Or. 41, 46-7, 584 P.2d 1371 (1978).
 Former ORS 17.355:
"(1) In civil cases three-fourths of the jury may render a verdict.
"(2) When a verdict is given, and before it is filed, the jury may be polled on the request of either party, for which purpose each shall be asked whether it is his verdict; if a less number of jurors answer in the affirmative than the number required to render a verdict, the jury shall be sent out for further deliberation. If the verdict is informal or insufficient, it may be corrected by the jury under the advice of the court, or the jury may be again sent out.
"(3) The jury in a criminal action may, in the discretion of the court, be polled in writing. If the jury is polled in writing the written results shall be sealed and placed in the court record."
The statute has been replaced by ORCP 59G.
 This need not involve reading each separate question to each juror. If each juror is asked whether he or she agrees with each part of the verdict as stated by the foreman or read by the clerk, only a juror who indicates otherwise needs to be asked with what part he or she disagrees.
 The plaintiff's exceptions to the comparative negligence instructions were:
"With respect to the comparative fault situation, I, of course, previously moved to strike all the allegations of comparative fault and I set forth, I think, my reasons pretty fully at that time. And I would just adopt those at this point, if that is satisfactory with the Court.
"* * *
"* * * that the only defense that would be applicable in this type of a case that remains in Oregon to a strict liability claim is the defense of misuse of the product or abnormal usage of the product; that lack of control, excessive speed, driving a loaded vehicle without experience, are not the types of conduct which the Supreme Court says should be a defense to a strict liability case. The instruction should not have been given, in any event."
 On this question, there are three lines of authority, which are succinctly summarized in Woods, Comparative Fault 108-109, § 5.5 (1978), as follows:
"Is apportionment to be made by comparing fault, or by comparing the extent to which fault contributed to the injury, or by making both comparisons? Most statutory language would seem to suggest that only faults are to be compared. For instance, the Colorado statute says that `any damages allowed shall be diminished in proportion to the amount of negligence.' [Colo. Rev. Stat. Ann. 41-2-14] Most statutes contain similar language. Some authorities, notably Prosser, take the position that `... once causation is found, the apportionment must be made on the basis of comparative fault rather than comparative contribution.' [Prosser, Comparative Negligence, 51 Mich.L.Rev. 465, 481 (1953)]
"Professors James [P. James, Connecticut's Comparative Negligence Statute, 6 Conn.L.Rev. 201, 216] and Fleming [Fleming, Law of Torts 241-42 (3rd ed. 1965)] do not agree. Their view is that both fault and causal contribution should be compared. It is supported by most of the cases. In Kohler v. Dumke [Kohler v. Dumke, 13 Wis.2d 211, 108 N.W.2d 581], defendant argued that if plaintiff were found negligent, `then in resolving the comparative negligence issue only the element of causation should be considered.' This is completely at odds with the Prosser view. The court accepted the approach of Professors James and Fleming. `We deem it clear that the word "negligence" in the comparative negligence statute ... means causal negligence ... Therefore, in comparing the negligence of two or more persons, the jury is to consider both the elements of negligence and causation'" (Emphasis in original.)
 Footnote 1 of the opinion sets forth some questions which we asked the parties. In answer to the third question, the plaintiffs attorney stated:
"The Court's third question appears to look beyond the disposition of this appeal. Unfortunately there may be no common rationale for comparing fault applicable to all strict products liability actions, and hence no sure basis for instructing the jury in other than the most general terms."
 In fact, comparative negligence has been a part of Oregon law since the passage of the Employers Liability Law in 1911. 1911 Or. Laws, ch. 3, § 6, now ORS 654.335. See Filkins v. Portland Lumber Co., 71 Or. 249, 256-258, 142 P. 578 (1914).
