10th Anniversary Of Supreme Court's Daubert Ruling

scraggly codger writes "Slashdot readers might find it interesting to learn about the ongoing legal controversy over the role of federal judges as gatekeepers for scientific evidence in civil and criminal litigation in the US. Ten years ago the Supreme Court provided guidelines for admissibility of scientific evidence in the Daubert ruling. Readers might find it hard to believe from the text of the ruling, but the result has been a huge increase in the power of judges to exclude scientific evidence from presentation to juries, based on what many scientists and other observers consider an incredibly naive (or perhaps merely self-serving) model of science. There's been a spate of news stories covering the topic, perhaps the most prominent in the WSJ of Friday, 27 June, "'Junk Science' Ban Also Keeps Jurors From Sound Evidence" (regrettably not freely available online). I particularly recommend Daubert: The Most Influential Supreme Court Ruling You've Never Heard Of."

      My gut reaction to this article would be that it's bad because it prevents a lot of scientific knowledge which could be important, but you make a good point about crappy science.

      My main problem with this though, is that I would think that instead of erring on the side of caution when it comes to science though, they should be more willing to risk erring on the side of the defendant, since proof beyond reasonable doubt (or clear and convincing proof depending on the case) is required, and if someone has reasonable scientific evidence in their defense, which may not be one hundred percent accepted, they should be able to use it. Obviously it should have to have some sound basis, but I think there should at least be more a little more leeway given on the defense side.

      Of course, this is assumes you believe that it's better to set an innocent man free than send a guilty one to jail.

    The real problem is it's apples and oranges. When they say "law" they mean "court cases". Legislation and common law (i.e., precedent) are infinitely and capriciously mutable. When they say "scientific conclusions" they don't mean "experimental results" but "theory", as the data gained from experiment is immutable, though its interpretation may be mutable, and the point of science is that theory is mutable but provably true within the known scope and margin of error. Whereas, as I said, the law is simply whatever a majority in a body (or an executive alone) accepts as agreeable, if not true. The law does not seek the truth, it seeks decisions consistent with its past decisions.

    The law courts are therefore the last place that the validity of scientific theory should be tested.

    Most civil cases come down to a "battle of the experts." An expert whose opinion is based on no foundation at all is simply not an expert, and his/her testimony doesn't help the jury. It may confuse the jury or skew the issues. That's why it's best that such testimony is completely excluded. That some relevant, good evidence may end up being excluded is a disingenuous argument. Whenever the rules of evidence are applied some good evidence can end up being excluded. Just because something is hearsay doesn't mean it's necessarily false. But it gets excluded nonetheless (unless it falls into an exception to the rule).

    They have fundamentally different ways of looking at the world, so naturally they interact badly.

    Science cares about external consistency. Scientists build models of the world, test them, and throw them away when they are inconsistent with observation.

    Law cares about internal consistency. One of the most important considerations is precedent - "we did it this way last time". When the world changes, precedent gets overturned - eventually.

    Science cares about reality. The gold standard in science is the published, reproducible procedure.

    Law cares about verisimilitude - believable stories. The gold standard in law is getting twelve members of the community to believe your story, and not just any twelve people - if a person has any expertise related to the matter in court, they will be filtered out of the jury pool.

    Science is never the last word. Observation can always make you change your model. Newton was the last word for centuries, now he's an approximation to Einstein.

    Law is supposed to be final, and it defends its finality fiercely - witness the resistance to checking old decisions with new DNA techmology, whereas in science the first thing you do with a new tool is compare it with your old measurements.

    Yeah, yeah, I know, Thomas Kuhn, postmodernism, yadda yadda... the above is the idealized way science works - reality is more complex and slow, but by and large peer review works.

    ...1923 ruling known as Frye, which held that the methods used by the expert in forming his scientific conclusions must be generally accepted within the expert community. Critics of Frye argued that it often excluded new but legitimate science that had not yet gained a consensus within the scientific community.

    This is the way that actual science works. Peer review. Lots of it, for a long time before every scientist starts believing in a result. There's a reason new methods are excluded, and it's because to scientists they aren't fully proven yet. I'm not really sure why they had to change this policy, or even the practical effects that this change had, aside from reading a few cases where perfectly acceptable sounding DNA evidence was excluded by a judge based on technicalities (one of the many things that makes it very difficult to prosecute a rape case). Perhaps the problem comes with the fact that so many conditions gives a judge too much wriggle room. The Fyre condition sounds pretty clear and simple in comparison to a four point checklist.

  12. The problem with scientists by gordona · · Score: 1, Insightful

    The cause of all this brouhaha with the legal system is because scientists are those folks who know more and more about less and less until they know everything about absolutely nothing.

    Seriously, I think that there is a kind of disconnect between high priests of science and the layity leading to a distrust of what science can offer. How often are there reversals in scientific opinion, such as has happened with eating eggs or drinking moderate amounts of alcohol. Then there are other cases, such as with the use of macro doses of Vitamin C, where lots of folks swear by it and science is either silent or negative. Then there are the cases where science "catches up" to common wisdom and the response is that science once again proves the obvious. Yawn.

    It would seem that the judiciary, as members of the scientific layity, are subject to the same opinions about science as many other commoners. They just have the power to do something about it, albeit it in an adverse manner.

    So the question might be that in the effort to eliminate junk science, as referred to in the article, judges are promoting a different form of junk science!

    The standard that is aimed for is "relevant and reliable." Not much to argue with there.

    But the political ramifications are great. On the one hand, exclude scientific evidence and risk ignorance of the truth. On the other hand, include scientific evidence and risk politicizing scientific knowledge.

    Consider one of the examples given: pollution.

    If we don't allow scientific diagnosis and treatment of the various problems associated with pollution, we'll almost surely mis-judge the relevance of pollution and possible routes to equitably manage it.

    However, if we seek scientific advice for diagnosis and treatment, scientists will be increasingly be the targets of bribery. The higher the stakes, the more sure the corruption. In that scenario, you get the same bad advice, but you malign the body of the scientific establishment as well.

    For evidence of this, look at the international debate on global warming. It's clear that financial interest is biasing the scientific arguments in the US policy analysis. Worse, once this debate is over, we can only assume the taste of money will remain on their tounges. It's easier to get grants for your dream research if you're owed a favor for a political performance.

    Further in the future, a stronger political capacity in the sciences could lead to more fundamental changes in the organization of our society. Historically, the ability to control truth and the ability to rule have proved dangerous in solution. If the church cannot be trusted in front of God, why then scientists in front of Reason? Prudence demands keeping both separated from the State.

    Looking at the history, you will find a great deal of garbage science cluttering both the lab and court rooms. We can find a large number of examples of smart people making bad decisions based on garbage science. Look at the large number of people who've fallen for Freud.

    What it does do instead is take a lot of credible science out of the courtroom and force jurors to decide on feeling rather than scientific findings.

    I believe that most jurors are trying to make their decisions based on facts...not just emotions...meaning that they are highly susceptible to garbage science.

    Jurors and lawyers neither have the time nor the skill to determine what is and what is not sound science. Jurors will make decisions based on whether or not the argument sounds scientfic. They also make decisions based on the credentials of the speaker. Jurors do not have the resources or skill to put each argument through their own independent review. Such reviews need to take place outside the court.

    Science should not be locked out of the court by over-zealous judges who are motivated by emotion.

    The problem I see is that the decision to include or exclude science in a case is being made by the judge presiding over the case. Since dismissing the arguments at the base of the case effectively determines the winner and loser, it is putting too much power in the hands of the judge.

    There should be a process for dismissing bad science...however, it should be through an independent peer review board of scientists, not by a judge who is more likely to be swayed by motives other than the foundations of the science.

The funny thing about psychology is that depending on whom you ask, a psychologist will blame only the accused, or the parents, or the school, or the media, or genetics, or or or. We psychologists have an amazing ability to snow people over with bullshit, and the push to publish generates some really questionable science. Lastly, our field does not tolerate reproducing earlier science much. For whatever reason, it's damned hard to get a PhD and gain credibility if you 'merely' reproduce someone else's work. One of the foundations of GOOD science is the replication of results, which weeds out much of the cruft. And one last thing, try getting published with null-results. It almost surely won't happen. Saying so and so, is a "respected, published expert" in such and such field of psychology doesn't always mean much.
