Alex Kozinski, Judge, United States Court of Appeals for the Ninth Circuit.

I guess I am here as the Daubert n1 expert. Having said everything there was to say about the case, both right and wrong, n2 I am cast in the somewhat unwilling position of defending Daubert. As may have been clear from my remand opinion in Daubert, n3 I was rather fond of Frye n4 myself. Of course, we were bound -- there had been an earlier ruling in the Ninth Circuit adopting Frye. n5 Hence, when we heard Daubert the first time, we were pretty much bound by that earlier precedent. But the Supreme Court is called the Supreme Court because it is supreme -- at least over the federal courts -- and we have the task of applying the rules it prescribes.

I first want to discuss what we, the Ninth Circuit, actually did with the Daubert case, and I will then move on to discussing some points made by my distinguished colleagues. Now, recall that the rule before Daubert was Frye. Frye said that expert opinion will be admitted only if it is based on a scientific technique generally accepted in the scientific community. n6 If you were an expert testifying as to X, you had to show that the technique by which you reached conclusion X was generally accepted in the scientific community. In Daubert, the Supreme Court threw out the Frye test and adopted basically a three-part test.  [*998] 

The first part, of course, is the premise that the witness must be an expert -- somebody who is qualified in the field. n7 Footnote two of the Supreme Court's opinion just waxes eloquent about what wonderful, terrific scientists the plaintiffs' experts in Daubert were. n8 Nobody really challenged their expertise; they were, in fact, qualified. Some were doctors and others were scientists. Thus, the first part of the Daubert test was satisfied.

Now, the second step -- and this is where Daubert and Frye diverge -- is that the testimony of any expert must be based on the scientific method. n9 The Supreme Court went on at some length about the scientific method and talked about how judges have to be gatekeepers. n10 On remand, this posed a dilemma for us. By hypothesis, we have somebody who comes in and testifies as an expert -- again, footnote two. You do not have a Daubert problem unless you have an expert. So by hypothesis it is somebody who is a scientist, qualified in the field. The expert testifies and says, "I used this method, and let me tell you, this is a scientific method." Well, he is a scientist, right? He ought to know. If he does not know, who does? What makes something a scientific method if not the fact that a bona fide scientist actually uses it?

Well, we considered that interpretation and decided that, no, the Court could not have meant that, or it would have stopped with footnote two, n11 as Judge Tochterman probably would. n12 The Court must have meant more. It did say more. The Court said that you have to see whether the evidence has been peer  [*999]  reviewed and whether it has been published. n13 You do not always have to have peer review and you do not invariably have to publish. n14 None of this is conclusive, but you have to show not just that the witnesses are scientists; you have to show that they are acting like scientists -- the "look and feel" test -- kind of a trademark test for scientists. n15

The Court tells us that in applying this new test, we should consider several factors. First, is the technique adopted generally accepted? n16 I think we have heard that one before. It was called the Frye test. n17 The first thing that a court has to look at is the Frye test, and if the evidence meets the Frye test, it is pretty much in. Second, has the evidence been peer reviewed? n18 In addition, you have to consider the error rate, the Court also said. n19 What is the error rate? I have no idea what this means, but there it is. The Court said this is not an exhaustive list. n20

On remand, we added one more factor to this list: Was this prepared for litigation? n21 Is it bad to prepare for litigation? We said no. However, if a scientist, who is busy working away in a laboratory, has some findings and testifies to those findings to help the case, that is almost conclusive proof that the scientist has followed the scientific method. n22 He is not in the business of testifying; he is just out there doing science that is relevant  [*1000]  and happens to testify. That is an inclusion test. If you meet that test, you are pretty much in; almost certainly under our reading of Daubert. But if not, the court has to look at the evidence and determine, even though they are scientists, whether they are acting like scientists. n23

Here is what we found: All the expert scientific evidence in the Daubert case involving limb reduction defects was manufactured for purposes of the litigation. n24 These were all real scientists, to be sure, but none of them had been doing research in the field before they were called upon to testify in the case. n25 Their interest in this particular area of science was entirely for the litigation. That is not so bad. Sometimes you start doing some litigation and, like Archimedes in the bathtub, you stumble across something useful. n26 But if you are a scientist, what would you do? You would certainly testify about it, but waste nothing. You know how it is: you start with a law review article, turn it into a speech and then an op/ed piece; you recycle everything. n27 If a scientist comes up with something in litiga  [*1001]  tion, you would expect him to get it peer reviewed. You would expect him to get it published. You would expect somebody in the community, other than the folks involved in the litigation, to take an interest in it. Imagine if, for purposes of litigation, you testified that you can create fusion in a bathtub. It would make a stir. People all over the world would undoubtedly be interested in that. People with bathtubs would be interested. You would expect that if there had been enough time and thought given to it, they would go out and try to do what scientists normally do. If that happens and it gets peer reviewed, we do not much care whether they generated the research for litigation because, at that point, science has engaged them. n28

On remand in Daubert, we found there had been a conspiracy of silence. None of the supposedly scientific reports had been published, none were circulated to other scientists, none were commented upon. n29 As we said in the opinion, there seemed to be an understanding out there that this was not science, it was litigation. n30 These were advocates; they created their reports to  [*1002]  feed to juries, not for use by the scientific community. Moreover, most of the experts said only Bendectin "could" cause birth defects, or it "might" cause birth defects. n31 There was only one expert who said that Bendectin actually caused the deformities. n32 Daubert tells us the fact that he is a scientist and the fact that he comes up with a conclusion is not enough. n33 He has to fill in the in-between parts. He has to convince us that the stuff in-between the "I have examined the children" and the conclusion, "the Bendectin caused the defects," was reached by the scientific method.

Remember, this is not Frye. It does not have to be the chain of analysis or technique that most scientists agree with. It could be Archimedes, so long as the methods employed are the normal methods of science. It cannot be done with a Ouija Board. It cannot be done by throwing pennies in a fountain. It cannot be done by saying "trust me." It is just not good enough. We have to see you do the things of science. In Daubert we found, as the Sixth Circuit had previously, that personal opinion, not science, testifies here. n34

Most of the evidence in Daubert failed on the ground of insufficient showing of scientific method, but not all of it. We considered whether we should, in fairness, send the case back to the district court. We considered whether, because the standard had changed so much, we should send the case back to let plaintiffs make a new showing -- let them shore up the testimony to fit the Daubert standard. n35

Instead, at this point, we looked at the third step in Daubert. Here is where the Court, I thought, had been really on target. Daubert said the testimony has to "fit." n36 It is not enough that it is scientific. It has to be relevant to something in the case; it has to make a difference. Consider Justice Blackmun's example: n37  [*1003]  He said if you bring in an expert about the phases of the moon, that may well be relevant when you are trying to figure out whether there was enough light. For example, if a particular witness were to testify about seeing a series of events, the phases of the moon might well be relevant to the question of whether he could see what he testified to. However, if you are trying to prove that the defendant was likely to be rabid because the moon was out, Justice Blackmun says the evidence is inadmissible. We realize that people will tell you that when the moon is full, people go berserk. I have seen An American Werewolf in London. n38 We know that people believe this, but it is not scientific. It does not fit with the theory of the case.

We looked at that third step in Daubert. This is where the case became really complicated because you have to ask yourself, under the substantive law, what does an expert have to say to make information useful, to make the evidence useful. n39 We looked at the substantive law of California. Of course, states can structure their substantive law almost any way they please. We applied California law, and California law said that the plaintiffs have to prove their case as to liability by a preponderance of the evidence. n40

Now, I want to talk a little bit about what plaintiffs' case looked like. This was not a case where the expert said, "I have examined these children and we have found traces of Bendectin in their bodies." Nor did they say, "here is the way Bendectin causes limb reduction defects." The experts presented largely epidemiological studies that showed an increased incidence of birth defects among children of mothers who took Bendectin. n41 There is a background incidence of birth defects, about two or three percent, n42 and there are limb reduction defects, which I  [*1004]  believe are one in a thousand even among children born to mothers who did not take Bendectin. n43 Thus, if you are looking at any one individual who has a limb reduction defect, there is some possibility that they would have suffered that defect even if their mother had not taken Bendectin. If you accept the proof offered by the plaintiffs' experts, there is some increase among children of women who took Bendectin, but none of them said that there is as much as a doubling of the probability. n44

This is where the law has some discontinuity. If you look at any one individual, you have to ask yourself the following question: Has he proven it is more likely than not that the defect was caused by the drug as opposed to other factors? If the incidence of limb reduction defects has more than doubled, the likelihood that any individual will suffer the injury as a result of Bendectin is more likely than not. n45 If the increase is less than a doubling, the probability is less than fifty percent. Therefore, if the probability is more than doubled, everybody recovers. If it is not doubled, nobody recovers. n46 While we recognized that there might be unjust results under this standard, we said that is a problem for state tort law to deal with. n47

The requirement that judges take a hard look at the methodology and at how the testimony of an expert interacts with the substantive legal standard is an important refinement of Daubert.  [*1005]  I think that the inquiry is far more pointed and ultimately it can allow more, better scientific evidence before the jury. There is this romantic view that we have faith in the jury and the jury can decide anything and will usually get it right. I think juries often do get it right. Unfortunately, the consequences when they get it wrong are staggering. The Bendectin litigation is a wonderful example. Look not only at the Daubert case, but at the whole series of lawsuits that were brought one after another after another after another. It is summarized in both of Peter Huber's books. n48 The question is how juries make decisions. Juries are kind of secret; we do not know much about what goes on. One reason to have the judges make the decision is that judges have to make decisions on a record that is reviewable, public, and open to criticism. Once something goes to the jury, it disappears behind closed doors.

Sometimes juries act out of passion. For example, a jury in an early Bendectin case found no liability, but wanted to award twenty thousand dollars to cover medical expenses anyway. n49 That is how juries think. There now have been a number of trials in the Bendectin cases, and the early trials established that there was no fault. n50 About eleven hundred cases were then consolidated. n51 The defense offered to settle for 120 million dollars; an offer the plaintiffs rejected. n52 The case then went to trial, and the defense won that case as well. n53 However, another jury awarded two million dollars to a six year old boy with club feet, n54 and still another jury awarded ninety-five million dollars  [*1006]  to another child with a birth defect. n55 As of 1993, twenty juries had reached verdicts on the merits of the Bendectin birth defect link; Merrell Dow had won twelve of those and plaintiffs had won eight. n56 All the while, of course, the FDA continues to approve the drug, n57 and it is still sold in most parts of the world.

Due to the litigation, Bendectin was taken off the U.S. market because the manufacturer decided it just was not worth it. n58 This might not seem like a big deal. It is no big deal for men, and it is no big deal for most women, who are lucky enough to go through a pregnancy and not have extreme nausea. But there is a small group of women who have extreme nausea throughout their entire pregnancy -- not just a little bit of morning sickness, but an extreme nausea, an inability to eat, to feed themselves, and to nourish their baby -- whose health is imperiled and whose baby's survival is imperiled because they are unable to take nourishment. n59 It is not a big, burning problem for most people. However, for the parents involved, for the mother, the baby, and the father in that situation, having a drug available that enables the mother to take nourishment is critical.

Pulling Bendectin off the market in the face of vast numbers of studies that have revealed no scientific relationship between the drug and birth defects n60 is not a minor matter, something we ought to shrug off. It is a disaster. And Bendectin is just one example of the way litigation has been used as a tool of legislation. n61 It is a tool of regulation when our administrative regula  [*1007]  tory agencies have said a product is safe, but juries have been misled into awarding damages. Think about the costs of running the machine that fends off litigation. It is just not worth it for a drug like Bendectin. Merrell Dow does not make enough money on it. It is a small market. It is very easy to crush, and it was crushed.

I now want to talk a little bit about criminal cases because I share Judge Tochterman's concern about them. n62 It seems to me that this is where Judge Tochterman should embrace Daubert and reject the California rule. As he mentioned, in the Alcala n63 and Page n64 cases, the California courts rejected expert psychological and psychiatric testimony about whether the defendant was induced to give a confession that he ought not to have given. I commend to Judge Tochterman and to all of you the opinion of the United States Court of Appeals for the Seventh Circuit in United States v. Hall. n65 In that case, the defendant had been identified as a suspect in the killing of a little girl, whose decomposed body had been found in a field. n66 It was much too late to get any physical evidence, but they got the defendant in a room and they got him to confess. n67 It was a good confession. It was nice and thorough. The Seventh Circuit nevertheless reversed the conviction. n68 The defense wanted to present testimony that the defendant had a mental disorder which caused him to be a "wannabe" -- somebody who wants to please authority figures. n69 He will agree to anything if put in the right situation. The trial court had excluded that evidence. n70 The Seventh Circuit said that, under Daubert, judges can no longer exclude such evidence. The judge might have been able to ex  [*1008]  clude it under Frye; because maybe this was not something accepted by the community at large. Under Daubert, however, the court has to determine whether the conclusion was supported by the scientific method. n71

I also would commend to you United States v. Cordoba, n72 decided by the Ninth Circuit on January 7, 1997. In Cordoba, my colleagues held that the rule of the Ninth Circuit excluding all polygraph evidence has been overturned by Daubert. n73 It used to be that polygraph evidence was excluded under all circumstances. n74 The defendant in Cordoba wanted to introduce polygraph evidence to show his innocence, but the trial court did not allow it. My panel said that though it had been excluded under Frye, Daubert changes the rule. The Daubert test helps defendants whose scientific evidence is derived via the scientific method. The judge is no longer allowed to throw out the evidence merely for lack of general acceptance in the relevant scientific community. Instead, the judge must go through and make a Daubert finding, considering all of the relevant factors.

Finally, I too was taken by the John W. n75 case that Judge Tochterman mentioned, n76 the one involving the penile plethysmograph. n77 There are about thirty-five cases on LEXIS involving this device. What you find is really interesting. As  [*1009]  Judge Tochterman reported, the evidence was excluded in John W. and Judge Tochterman speculated that the case would come out the same way under Daubert because no evidence was presented that this was derived via scientific method. I am not at all sure that this is the case. Dr. Walker, the expert in John W., testified that he had in fact done a study involving pedophiles at Atascadero. n78 He had found the plethysmograph to be a reliable means of diagnosing whether somebody is a pedophile. n79 The methodologies used by Dr. Walker sound very much like the kind of thing Daubert would find acceptable. He had a bunch of people. He divided them into a test group and a control group, and he found that the "results obtained at Atascadero State Hospital and other treatment centers show that eighty percent of convicted sex offenders tested showed a positive response to the deviant stimuli for which they were convicted." n80 I do not see at all why that would be excluded under Daubert. But there was another fact that, under Daubert, might make the case come out the same: Dr. Walker found that some of the convicts did not react either to the pictures of young boys or to the pictures of women. They had no reaction at all. n81 Suppose our defendant is one of those guys. It seems to me that under Daubert this testimony would not have been relevant as to him. It would not "fit." It would be different if he had said that whenever they put a naked woman up on the screen, there was an increase in the blood flow; but when they put up a young boy, the blood flow decreased. That, it seems to me, would have been a "fit."

Let me add one more note of caution. There are two cases out there involving the plethysmograph, both of them in the State of Georgia, where the prosecution offered evidence that they put the plethysmograph on the defendant and he reacted to the young boys and did not react to pictures of women. Therefore, the prosecution argued, he is a pedophile, and he more likely than not committed the crime charged. The first case was Gentry v. State. n82 In that case, the Georgia Court of  [*1010]  Appeals threw out the conviction under essentially a Frye standard. n83 We have to ask ourselves, would they have admitted it under Daubert? It seems to me, once you start admitting that kind of stuff for the defense, you are going to have to admit it for the prosecution as well. In the second case, Tuttle v. State, n84 there was no objection to the plethysmograph results. n85 The appellate court let the conviction stand because the defendant failed to object. n86 Thus, at least one person is in jail convicted, in part, by the plethysmograph.

Now, I would like to comment briefly on the Dutch judgment presented by Judge Nijboer. n87 I was actually quite taken with it. I like the idea of having experts who are not dependent on parties. But let me throw out a couple notes of caution.

There is something about the way we make decisions that favors a decisionmaking process that is reviewable and public. Under the Dutch system, when the experts come together and determine whether X is the scientific fact, Judge Nijboer tells us that they agree almost all of the time. They try to reach an agreement on every case. No one, no trial judge, no appellate judge, is then in a position to dispute their findings. Essentially, the decision is made by the experts in secret. The experts, in a way, become the judges. That worries me. I do not know enough about the Dutch system to say much more than that.

I am also a little bit concerned about the one sentence in Judge Nijboer's mock opinion that says: "If causation could be proven, [the drug company] should be held liable for the damages." n88 Yet later on, in Part 5 of the opinion, the Court recognizes that this was not something that was either known or  [*1011]  could have been foreseen. n89 Nobody knew this. Let me just ask, why would there be liability if the drug company has obtained approvals from administrative agencies, and has suffered the burdens and costs of testing the drugs? They have gone through all the requirements of the law and at the time there is nothing out there, according to the judgment, that suggests a basis for suspecting there is a relationship between the drug and birth defects. Why would the drug company be liable? Why do we not say it is a misfortune? It is one of those misfortunes that is part of life, just like lightning, just like birth defects themselves. We should not deprive those other women and their babies of a potentially useful drug because something unfortunate happens.

So overjoyed with the excitement of his discovery -- known as Archimedes's principle -- he leapt from his bath and ran naked through the streets shouting "Eureka!" ("I have found it"). As it turned out, the King was none-too-happy. See 13 The New Encyclopedia Britannica 930-31 (15th ed. 1986) (discussing Archimedes's principle and story behind it).

Bendectin litigation has been pending in the courts for over a decade, yet the only review the plaintiffs' experts' work has received has been by judges and juries, and the only place their theories and studies have been published is in the pages of federal and state reporters. None of the plaintiffs' experts has published his work on Bendectin in a scientific journal or solicited formal review by his colleagues. Despite the many years the controversy has been brewing, no one in the scientific community -- except defendant's experts -- has deemed these studies worthy of verification, refutation or even comment.

In terms of statistical proof, . . . plaintiffs must establish not just that their mothers' ingestion of Bendectin increased somewhat the likelihood of birth defects, but that it more than doubled it -- only then can it be said that Bendectin is more likely than not the source of the injury. Because the background rate of limb reduction defects is one per thousand births, plaintiffs must show that among children of mothers who took Bendectin the incidence of such defects was more than two per thousand.

n46 See id. at 1320 n.13 ("No doubt, there will be unjust results under this substantive standard. If a drug increases the likelihood of birth defects, but doesn't more than double it, some plaintiffs whose injuries are attributable to the drug will be unable to recover.").

n52 After Merrell Dow made the settlement offer of $ 120 million, the district court certified a "non-opt out" class for settlement purposes. Although a majority of the class counsel favored the settlement offer, several individual plaintiffs were successful in challenging the certification order. See In re Bendectin Prods. Liab. Litig., 749 F.2d 300 (6th Cir. 1984) (issuing writ of mandamus vacating certification order of district court).

n76 Tochterman, supra note 12, at 1021-22.

n77 For those unfamiliar with the penile plethysmograph test, the expert in John W. described it as follows:

This is an electronic device that fits over the man's penis. And he wears it while he views slides of naked women of various ages, one through adulthood. Also while he listens to audio tapes. A total of 12 tapes altogether, which vividly describes sexual activity either with an adult or with a child. And there's sic various tapes. In some tapes the child's sexuality is obviously forced. And in others the child is ostensively sic consenting, as the child doesn't struggle. And the device measures any changes in the blood flow to the penis, or erection. It can measure erections in percentages, one hundredth of an erection all the way up to a hundred percent of an erection. So it is a physiological measurement of arousal, of sexual arousal, specifically.

n83 The court stated that "given the rejection of penile plethysmograph evidence by other states, and particularly the uncertainty within the scientific community of its reliability, we hold that it is inadmissible in Georgia." Id. Finding admission of the evidence not to be harmless, the court reversed the conviction. Id.
