Can 'gatekeeper effect' bolster weak opinions?

The much ballyhooed Daubert decision of 1993 was intended to minimize the effect of so-called "junk science" in the courtroom. ("Junk science," by the way, was a term popularized by the book Galileo's Revenge, part of an orchestrated corporate attack on class action litigation, but that's a story for another day.) But Daubert may be having a paradoxical effect instead, of lending greater credibility to expert witness opinions.

That is the premise of the lead article in Psychology, Public Policy and Law, by Nick Schweitzer and Michael J. Saks of the Law and Social Psychology Research Group at Arizona State University.

The "gatekeeper effect" is the label being given to this phenomenon, of jurors giving extra weight to scientific evidence just because it has been vetted by judges.

Remember that formal rules of evidence are aimed at excluding improper evidence from jurors' consideration. And under the U.S. Supreme Court's ruling in Daubert, judges have become more and more responsible for filtering evidence prior to its admission.

Two experiments tested whether mock jurors (as usual, university undergrads rather than real-life jurors or eligible jurors) were more persuaded by evidence when they thought a judge had filtered it. The findings: A key predictor of how much stock the jurors put in scientific evidence was whether they thought a judge had deemed it acceptable.

Why is this potentially problematic? Judges, as many of us know, are not always well prepared to serve as filterers of scientific evidence. Some of them do not do it well. Also, in many jurisdictions, Daubert is not the law, so jurors may be assuming incorrectly that the evidence they hear has passed through a filtering system.

Concludes the article, "When judges allow expert testimony to reach the jury, they are implicitly lending credence to the testimony, increasing its persuasiveness. This tips the scales toward the party offering the expert witness, perhaps affecting the jury's verdict. Ironically, a landmark Supreme Court decision motivated in large part by a desire to shield jurors from 'junk science' could serve to heighten the impact of false or misleading scientific evidence when judges allow it through the courtroom gates."

I find it a bit troubling that jurors may be persuaded by expert testimony that is false, misleading, or scientifically weak, based on incorrect assumptions about the process. I don't, however, find it too terribly surprising.

Embitterment disorder: The latest from DSM-V

My regular readers know all about the DSM-V revision controversies (click HERE for more), and the efforts of some psychiatrists to make the manual ever-more-expansive, until just about nearly every human condition becomes a formal pathology.

But, really, folks. Post-traumatic embitterment disorder? Isn't that going a bit far?

The L.A. Times' Shari Roan has the story of how some psychiatrists want to create a formal label for embittered people bent on revenge. We all know them; now we'll have a handy-dandy acronym -- PTED -- by which to refer to them.

The article is part of Ms. Roan's ongoing coverage of the heated DSM debates at the American Psychiatric Convention in San Francisco. Today's coverage is here.

Oops! Another accidental deportation

Getting arrested, even on a minor charge, can be hazardous in unexpected ways. Especially if you are mentally impaired and have brown skin and/or a Latino surname.

Remember Pedro Guzman, the cognitively handicapped Los Angeles man who was arrested on a minor trespassing charge and accidentally deported to Mexico, where he disappeared for months?

Now, it's happened again.

This time, a North Carolina native who speaks not a word of Spanish ended up on a cross-national odyssey after ICE scooped him up from a local county jail and shipped him off to Mexico. Perhaps fortunately, what with the swine flu and all, Mexico quickly deported him to the Honduras, which deported him to Guatemala. In all, Mark Lyttle bounced among Latin American prisons and homeless shelters for four months before the U.S. Embassy in Guatemala finally confirmed his U.S. citizenship.

Lyttle is mentally retarded and mentally ill. Although his surname does not hint at a Mexican nationality, he has dark skin, thanks to the Puerto Rican ancestry of his birth father. ICE claims Lyttle falsely identified himself as a native of Mexico, a claim Lyttle adamantly denies.

And just as Lyttle was finally making his way home again, you'll never guess what happened: immigration officials at the Atlanta airport tried to deport him yet again!

The Raleigh News & Observer has the story HERE. My blog posts on the 2007 case of Pedro Guzman are HERE.

NCIC critiques actuarial risk tools

The promise of violence risk prediction in corrections has "trumped actual performance," warns a report from the National Council on Crime and Delinquency.

Indeed, in its pell-mell rush to implement defensible, "evidence-based practice," the criminal justice field has abandoned clarity and parsimony in favor of a confusing hodge-podge of practices that lack proven reliability and validity, asserts the report, A Question of Evidence.

The report is authored by Christopher Blair, executive vice president of the NCCD, which is the oldest criminal justice research organization in the United States and a pioneer in evidence-based classification schemes in child protection and foster care.

The report critiques the sloppy use of buzzwords such as "criminogenic needs" and "protective factors." "These are important concepts, but ones that require a significantly deeper level of assessment than many risk models currently provide. As such, they can raise false expectations and lead to inappropriate case plans and services."

The NCIC is advocating that juvenile and adult corrections administrators step back and take a critical look at the actuarial tools, lest flawed instruments, approaches, and terminologies become so entrenched that they are impossible to change.

The report is available HERE.

Forensic Psychology Unbound

That's the clever title of a new website launched by a group of forensic psychologists promoting an online, open-access journal. The first issue of the Journal of Forensic Psychology is in the works, and editor Greg DeClue is encouraging interested professionals to submit manuscripts. The journal will be free and accessible to anyone with Internet access. This stands in stark contrast to most professional journals, which have long been critiqued for being extremely costly and inaccessible to professionals without a subscription or members of the public who don’t have access through academic databases.

The new journal features several of the same editorial board members as a more narrowly focused effort at an open-access forensic psychology journal, the Journal of Sexual Offender Civil Commitment, launched by psychologist Joseph Plaud in 2005. Board member R.K. McKinzey sponsors a third online, open-access forensic psychology site, Web Psych Empiricist, with a neuropsychology emphasis. The breadth of interest areas of editorial board members bodes well for the new journal.

Sponsoring the new project is Professional Resource Press, which was founded by psychologist Larry Ritt a few decades ago, and is a continuing education sponsor approved by the American Psychological Association.

You can help the project succeed by submitting manuscripts, taking the APA-approved Continuing Education offerings, or simply donating money -- online, of course. The home page sports a piggy bank which is not yet open for business.

Profiling the Drug Wars

Wouldn't it be a drag to get arrested for something you did not do based solely on the word of a lying, mentally ill drug addict?

That's what happened to Regina Kelly in rural Hearne, Texas in 2000. Ensnared in a mass arrest of suspected drug dealers at her housing project, the young single mother was charged with selling drugs in a school zone. Despite her insistence that she was innocent, her court-appointed attorney pressured her to accept a plea bargain to avoid many years in prison and the loss of her children. With no criminal record and no drugs found on or near her, she refused.

Instead, with the help of the American Civil Liberties Union she filed a class action suit, Regina Kelly v. John Paschall. Since the case settled four years ago, the local drug task force has been disbanded.

As it turns out, bogus statements by "snitches" trying to curry favor with police are a leading cause of wrongful convictions (along with faulty eyewitness evidence and wrongful confessions). In the U.S. Drug Wars, this especially affects those who, like Kelly, are poor and Black. Texas seems like an unlikely leader in the campaign to reform such practices. But, prompted by the Hearne case and another mass drug arrest the year before in Tulia, the Lone Star State became the first in the United States to enact legislation requiring that the statements of confidential informants be corroborated by other evidence.

The case was reported by PBS' cutting-edge Frontline back in June 2004; a similar documentary was made about the more infamous bust in Tulia, Texas. But now, a fictionalized version of Kelly's story is set to reach a broader, mainstream audience. Co-director Bill Haney says that when he heard about Kelly's case on National Public Radio as he was driving along, it so moved him that he pulled his car over to the side of the road and cried.

In American Violet, "Dee Roberts" (Nicole Beharie) is the plaintiff in a class-action case over racial discrimination in drug enforcement. Tim Blake Nelson plays David Cohen, the ACLU lawyer who sues racist district attorney Calvin Beckett (Michael O’Keefe) on her behalf.

Kelly says the film is "90 percent accurate." The depositions, the courtroom scene in which she fights to retain custody of her children, and many other scenes are word-for-word accounts.

"I'm hoping that somehow, this film is going to get the message out there for someone to look in on this town and other towns that go through the same thing that we go through," Kelly told the Chicago Tribune. "Because something has to happen, and this has to stop."

With this film, Kelly may get her wish. Like Clint Eastwood's magnificent The Changeling (see my review HERE), this tale of a defiant woman's struggle against corrupt law enforcement strikes a universal chord. But unlike The Changeling, American Violet also addresses present-day criminal justice themes of racial profiling and coerced plea bargaining.

Get out and catch it.

The L.A. Times has an informative review HERE. Grits for Breakfast has compiled a list of links to other media reviews. For more information on the true case, see Kelly's website. Or, you can watch Kelly on YouTube. My prior posts on confidential informants are HERE.

DNA science on trial

My least-favorite crime show is CSI. And my least-favorite line in that show is "The science never lies." Talk about a whopper!

With all of the revelations lately about faulty science -- from handwriting identification to fingerprint evidence, ballistics, arson investigation, and even bite marks -- it is reassuring that at least one type of scientific evidence rests on a solid foundation.

That's DNA, of course. After all, as I have heard DNA experts testify many times in court, the likelihood of a wrong DNA match is something along the lines of one in 1.1 million, or less.

But what if that's just one way to run the math? What if you can run it another way, and the odds of a wrong match rise to a whopping one in three? And what if the FBI knows this, and is working feverishly to keep such information hidden from the public and out of the courts?

That is the alarming cover story by Pulitzer Prize-winning author Edward Humes in this month's California Lawyer magazine.

As Humes cogently explains, the problem is not so much with the matching of crime scene DNA to a known suspect. The problem is with the cold cases, when a database spits out a match to an offender who is not already identified as a suspect. The larger the databases get, the greater the odds of a wrong match by pure chance. Especially if the crime scene DNA is degraded, and fewer than the ideal 13 loci (DNA locations) are available for comparison.

This problem was confirmed by a technician at a DNA lab in Arizona back in 2001. Running an experiment by comparing all 60,000 offenders in her state's database, she was shocked to find about 90 coincidental matches. The FBI, unhappy over her disclosure, "began threatening sanctions against crime labs that shared such information with anyone outside of law enforcement," Humes reports.

Experts maintain that wrong matches are becoming more and more inevitable, given the increasing sizes of DNA databases. In California, for example, with the third-largest DNA databank in the world, a new policy of profiling everyone arrested for -- not just convicted of -- a felony is enlarging the database by 35,000 profiles per month.

Donald Kennedy, a former Food and Drug Commissioner who contributed to the recent National Research Council report critiquing the management of government forensic labs, confirmed that the science "is being shut out of court."

That may be forced to change, depending on the outcome of several appeals around the United States. For example, a 71-year-old wheelchair-bound man convicted of a 1972 rape-murder in San Francisco is appealing his conviction on the grounds that the jury was not allowed to hear the alternate statistics. Although John Puckett had other sex offense convictions, only a cold hit to some badly degraded DNA at the crime scene tied him to this one. There were no eyewitnesses, footprints, fingerprints, or confessions. (The case is People v. Puckett, No. A121368, Cal.Ct.App., 1st District, May 1, 2008.)

The National Research Council is calling for change. In their February report, they recommend improving reliability and transparency by taking the databases out of the hands of law enforcement and prosecutors entirely.

In the meantime, jurors -- hearing only the cheerleading version of the science -- will keep believing the CSI mantra that the science never lies.

Brave judge tosses sexual assault conviction

Jessica's Law: Cruel and unusual punishment?

Jurors in criminal cases are generally kept blind as to the punishment that will be imposed if they find someone guilty. For that reason, one juror was dismissed during deliberations in a trial in Sonoma County, California, when he learned the potential outcome. The juror said he could not sleep once he realized that his guilty vote on a sexual assault charge could send the young defendant to prison for life.

Apparently, the judge in the case was similarly troubled.

Instead of sentencing 24-year-old Jaime Hernandez Gonzalez to life in prison yesterday, Judge Gary Medvigy dismissed the jury's conviction of assault with the intent to commit a sex crime during a burglary. He replaced it with a lesser conviction, residential burglary, which carries a maximum of six years in prison.

But the judge -- a former prosecutor and an Army reserves brigadier general who was decorated for his service in Iraq -- didn't stop there. In tossing the conviction, he read a lengthy statement questioning prosecutors' commitment to justice in light of the facts of the case.

Sentencing a young man with no prior criminal record to spend the rest of his life in prison for a crime that involved no violence or completed assault is so "grossly disproportionate" that it constitutes cruel and unusual punishment, the judge ruled.

In the rather bizarre case, Gonzalez entered a home through an unlocked sliding door, stripped naked, and accosted two sleeping women, removing the pajama bottoms of one. When the women screamed and ran away, Gonzalez fled too. The women testified that Gonzales appeared "zombie-like" or "comatose" during the assault, even when they screamed at him.

The judge slammed the 2006 Jessica's Law expansion under which Gonzalez was convicted, which mandates life imprisonment for sexual assault during a burglary, as "poorly drafted." He said it may be so overly broad as to be unconstitutional, because it requires the same punishment for crimes "involving minimal misconduct" as those involving severe violence and danger.

The District Attorney’s Office expressed outrage and threatened an appeal.

Meanwhile, the legal community in sleepy Sonoma County was abuzz over the judge's highly unusual action, according to news reporter Lori Carter, who covered the trial for the Santa Rosa Press-Democrat. Carter quoted a veteran attorney as calling the decision "gutsy":

"A lot of judges wouldn't do that because of politics. They're worried about reelection," said defense attorney Walter Risse.

Medvigy's conscientious stance will definitely cost him. The public hysteria over sex offending is manifested in the online comments to the Press-Democrat coverage, with vitriolic attacks and calls for the judge's ouster far overshadowing the few attempts at rational discourse.

Salon on Army PTSD diagnosis scandal

Many of my forensic psychology students have signed up with the military after getting their graduate degrees. A main reason is to get the student loan monkey off their back; the military will forgive their massive debts. That is hard to resist. But at what price service?

Today's Salon features an audiotape of civilian psychologist Douglas McNinch explaining to a combat veteran the pressure the military puts on treatment providers not to diagnose Posttraumatic Stress Disorder:

"I will tell you something confidentially that I would have to deny if it were ever public. Not only myself, but all the clinicians up here are being pressured to not diagnose PTSD and diagnose anxiety disorder NOS [instead]."

The audiotape, secretly recorded by a patient labeled "Sgt. X," confirmed what "wounded soldiers and their advocates have long suspected -- that the military does not want Iraq veterans to be diagnosed with PTSD."

Why not? Because Posttraumatic Stress Disorder would require paying for expensive, intensive treatment, including possibly lifelong disability payments. Large numbers of vets suffering from severe trauma might also dampen public enthusiasm for war, and make recruitment even more difficult than ever.

After the tape surfaced, the Senate Armed Services Committee refused to investigate, and the Army conducted its own internal investigation that cleared itself of any wrongdoing. What a surprise.

Perhaps some of you have seen Michael Moore's award-winning documentary, Fahrenheit 9/11, which shows predatory recruiters prowling shopping malls in poor communities scouring for fresh meat. Or the harrowing movie Stop-Loss, about how hard it is for some to get out of the Army once they have served their time.

Many young people come home damaged or destroyed, with invisible but severe traumatic brain injuries (as I blogged about two years ago) or severe psychological trauma. After the military chews them up and spits them out, psychologists like my former students are supposed to put them back together again.

But, hey, it's really not that bad. It's only Anxiety Not Otherwise Specified. How hard can that be to treat?

"COMING HOME" is the title of the excellent Salon investigative series about U.S. Army troops who have returned from Iraq. Focusing on troops at Fort Carson, Colorado, Salon reporters reviewed more than two dozen incidents of suicide, suicide attempts, prescription drug overdoses and murder, much of which "could have been avoided if the Army did a better job of recognizing and treating the symptoms of post-traumatic stress disorder."

Those of you who are attending next week's Forensic Training Institute in Oakland, California, will get to hear more about diagnostic shenanigans and the controversy over forensic use of the PTSD diagnosis. (Hopefully it's not too late to sign up, if you haven't done so already.)

New book reviews

In the mood for some spring reading? My review of The Wrong Guys by Tom Wells and Richard Leo is now available online at the California Lawyer website. Here is how the review begins:

Innocent people do not confess. Especially to rape and murder.

That is the belief of most people, including jurors, judges, attorneys, and even the very police detectives who induce false confessions. It is supported by TV police dramas, in which the cops always nail the guilty, and the guilty then tell all.

The belief is strengthened by the emotional nature of confessions. Jurors find such declarations the most compelling of all evidence. And once a jury votes to convict someone who has confessed, reversal or exoneration is well-nigh impossible.

The Norfolk Four case is the perfect vehicle to challenge this misguided faith. A routine investigation into the murder of a young sailor's wife in 1997 turned into a runaway train, as detectives blindly pursued a gang-rape scenario that was inconsistent with physical evidence suggesting a lone assailant. Each time a suspect's DNA failed to match the sample found at the crime scene, the detectives added another suspect, essentially at random, until their list grew to at least eight.

Postpartum psychosis stirs Texas controversy

A proposal to carve out a reduced penalty for a very limited type of infanticide is causing quite a furor in Texas.

The law being proposed by two state legislators would make postpartum disorder a legal defense for women who kill their children in the first 12 months of life. The defense would not come into play until after a conviction. Then, at the sentencing phase, jurors could hear mitigating expert testimony about the mother's mental state that could reduce the sentence to a state jail term.

Similar laws are on the books in 29 nations -- including Britain, Australia, and Canada -- but this would be the first in a U.S. state.

Currently, postpartum psychosis cases are very disjointed under the law; some women are found insane and go to mental hospitals, while others with almost identical crimes are found guilty of murder and go to prison. Women may still attempt an insanity defense if this law is passed, but it is difficult to prevail under the narrow legal theory of insanity.

It will be interesting to see whether the modest law passes. If it does, that will be a sign that the Hang 'em High state is becoming a kinder, gentler place.

It won't come easy, though. Since the legislation was proposed last week, Texas talk radio and the internet have been abuzz with amateur pundits who fear a wave of mothers murdering their children if they know they can get away with it.

What a joke. Most women who kill their children while in a state of postpartum psychosis or severe depression are so overwhelmed with guilt when they regain their senses that they can barely go on. Many commit suicide the first chance they get.

Readers will recall that Texas was the site of probably the most high-profile case of filicide in recent years. Andrea Yates, who drowned her five children in the bathtub in 2001, was found not guilty by reason of insanity and remains psychiatrically hospitalized.

After that came Dee Schlosser, who in 2004 killed her daughter by cutting off her arms. Police found Schlosser soaked in blood and humming a hymn; she believed her deed was an offering to God. She too was found insane.

The Schlosser case may be making Texans especially prone to outrage at the moment. Just a few months ago, they learned Schlosser is being released from a state mental hospital, and some equate that to "getting away with murder." But as Lucy Puryear, MD, an expert witness at Yates' insanity trial, commented over at Women in Crime Ink:

Dee Schlosser will never live a carefree life. She must live with the knowledge and memory of killing her child. She will no longer be able to care for or have contact with her other children, and her marriage ended in divorce. What kind of life will she have? Can you imagine waking up every day to that horror?

She is no longer psychotic, she is on medication, she will be monitored by a psychiatrist to make sure that she remains well. So why should she remain in the hospital; just so our sensibilities are appeased? That's a waste of money. Her being in the hospital does not protect you or your children. Dee Schlosser has no intention of coming to your house to cut off the arms of your child.

Puryear makes a good point. And probably most people would agree, when they think about it, that women like Schlosser and Yates aren't much of a danger to society. The problem is that people don't think. A mother killing her child triggers such visceral rage that the only color people see is red.

Gender twist on "post-apocalpytic trolls"

I've written previously about troll colonies. They are the exiled sex offenders living under bridges, including most famously the Julia Tuttle Causeway in Florida. Now, for perhaps the first time, a woman has been forced to join their ranks. Here is what one columnist had to say about this sad, and senseless, development in a world gone mad:

Woman joins sex-offender group
Guest essay by Fred Grimm, Miami Herald*

It's as if Voncel Johnson has been thrust into a bizarre social experiment.

Forcing so many men to live like post-apocalyptic trolls beneath a bridge in the middle of Biscayne Bay wasn't quite mad enough. Now they've added a woman.

For two years, a colony of convicted sex offenders under the Julia Tuttle Causeway has lived in a public health travesty, without water or toilets or electrical service. They sleep in tents, shacks, the back seats of cars in the last realistic address in metropolitan Miami unaffected by city and county sex-offender residency laws.

The numbers have been growing steadily as more convicted sex offenders emerge from prison and are consigned to finish out their wretched lives under a bridge.

The population was up to 52 men Monday. And Voncel Johnson.

Gender equity

In a peculiar nod to gender equity, the Florida Department of Corrections informed her last week that she too had only one residency option in Miami-Dade County -- the Tuttle. ''They just give me a blanket and a pillow and sent me . . . here?'' she asked, talking over the incessant thump-thump-thump of the freeway traffic overhead. "I just broke down.''

A community backward enough to create a subterranean de-facto prison camp of male sex offenders thrusts a single woman into the mix -- just to see what happens.

It's an ironic setting for Voncel Johnson. The 43-year-old woman, who grew up in poverty and neglect in the Brownsville section of Miami, told me she was sexually molested at age 6 and gang-raped at 16. ''I have a hard time trusting men,'' she said.

In 2004, Johnson pleaded guilty to a charge of lewd and lascivious exhibition (without physical contact) with a minor. She claimed Monday the charge was unfounded but at the time a plea offer with one year probation and no prison time seemed prudent. Except she twice failed to meet sex-offender registration requirements. Her probation was revoked. She did 10 months at Broward Correctional Institute.

Common refrain

She repeated a common refrain -- sometimes delusional -- among the bridge outcasts. "I never would have done that plea deal if I'd known they'd send me here. I could've fought those charges.''

But offender laws leave the state Department of Corrections no options for a sex offender. Voncel Johnson's parole officer did find her a motel room for three days last week. And she was offered a slot in a residential offender program in another county. But Johnson refused to leave Miami. "All my family lives here. I've never been any place but Miami.''

It was probably a foolish decision, but Johnson harbors some vague notion about gutting it out beneath the Tuttle until her parole ends May 5. ''Then I can find some place to live.'' She seems unable to grasp that residency restrictions are forever.

Meanwhile, the men beneath the Tuttle gave her a battered old camper trailer. ''We watch out for her,'' insisted Juan Carlos Martin, who has been under the bridge so long that the address on his driver's license reads ''Julia Tuttle Causeway Bridge.'' He said it was as if city, county and state officials purposely cram more and more men into an unliveable, hopeless, crowded space, knowing that eventually something awful might happen. And now they add a woman.

Martin said, "They need to get her out of here.''

Sex Offender Laws: Failed Policies, New Directions

Here's an important new book for you folks who work with sex offenders:

In response to many high-profile cases of sexual assault, federal and state governments have placed a number of unique criminal sanctions on sex offenders. These include residency restrictions, exclusionary zones, electronic monitoring, and chemical castration. However, the majority of sex offender policies are not based on empirical evidence, nor have they demonstrated any significant reductions in offender recidivism. In fact, some of these policies have unintended consequences, which actually increase the likelihood of sexual offenses.

In this book, Richard Wright critically analyzes existing policies, and assesses the most effective approaches in preventing sex offender recidivism. This provocative and timely book draws from the fields of criminal justice, law, forensic psychology, and social work to examine how current laws and policies are enacted and what to-date is known about their efficacy. In response to the failed policies of sex offender laws, this book presents alternative models and approaches to sex offense laws and policies.

Topics include:

• History and politics of sex offender laws
• Internet sex stings
• Registration and community notification laws
• GPS monitoring
• Residency restrictions
• Chemical and surgical castration
• Civil commitment
• Death penalty
• Containment approach
• Sexual violence and restorative justice
• Victim impact

Richard G. Wright is a criminal justice professor at Bridgewater State College in Massachusetts and a nationally known expert on sex offender laws.

Crazy but sane, Texas court rules

Remember Andre Thomas, the eye-plucking Texas prisoner I blogged about back in January? The delusional schizophrenic guy who killed his wife and two children, ripped out their hearts, and then walked into a police station and confessed? The fellow who plucked out one eye shortly after the crime, and the other eye just a couple of months ago?

Yesterday, in rejecting an appeal of his death sentence, a Texas appellate court ruled that Thomas "is clearly 'crazy,' but he is also 'sane' under Texas law."

At Thomas' trial, the defense argued that the killings were the result of insane delusions caused solely by Thomas' mental disease. Prosecutors countered that his psychosis was caused or aggravated by his voluntary use of alcohol, drugs and prescription drugs.

The court also rejected an appeal argument that Thomas was not competent to stand trial at the time of his 2005 trial:

"Although reasonable people might well differ on the questions of whether (Thomas) was sane at the time he committed these murders or competent at the time he was tried, those issues were appropriately addressed by the defense, the prosecution, trial judge, and the jury during the trial," wrote Judge Cathy Cochran of the Texas Court of Criminal Appeals in a concurring opinion.

Scott Henson over at Grits for Breakfast found the ruling ludicrous:

It's just ridiculous to send somebody who's so obviously nuts to death row - what's the moral point of killing a guy who'd mutilate himself to death if you let him? What's the insanity defense for if not cases like this one? … How can the court just assume Thomas' substance abuse wasn't a symptom of his mental illness - a form of self-medication, perhaps? Which came first, the chicken or the egg?

Psychiatrist Lucy Puryear, writing at Women and Crime Ink, agreed:

Non-mentally ill people do not pluck their own eyes out for some secondary gain…. To those of you who would suggest that I am soft on crime, consider this novel idea. How about we make mental health treatment available in the community to those who need it. Had Mr. Thomas been adequately treated and monitored he never would have killed his family or plucked out his eye. Three people would be alive today and an enormous amount of money would be saved keeping him out of the prison system. That's not soft on crime, that's preventing crime.

As one solution, Dr. Puryear advocates specialized mental health courts, which are popping up quite regularly in courts around the United States these days:

Instead of the revolving door from prison to back on the streets where psychiatric care is lacking, then back in prison when another crime is committed, these persons can be put into a system where follow-up is mandatory and resources are available.

Tragically, Thomas had twice sought psychiatric help at local hospitals shortly before the crime, but had not stuck around voluntarily and could not be detained against his will.

Competent and sane, you betcha.

"No Lie" fMRI to be introduced in court?

Last week, I blogged about neuroscientists' concerns about fMRI brain imaging. Critics say its scientific reliability and validity is far from established, and that if it was introduced in court, its colorful graphics might mislead jurors and judges and derail justice.

Just days later, the good folks over at the Stanford Center for Law and the Biosciences have learned of a pending case in California in which the "No Lie MRI" (I kid you not!) may be introduced in court to establish that a parent did not molest his child.

The case is a child protection hearing in juvenile court, so the records are sealed. The issue is whether a child should be removed from the home due to alleged sexual abuse by a parent, explains blogger Emily Murphy, a Stanford Law School fellow.

According to Murphy, a hearing is imminent on whether the fMri-based "truth verification" technique will be allowed in court. Under California's Kelly-Frye standard for evidence admissibility (which is different from the federal Daubert test), a scientific technique cannot be introduced in court unless it is generally accepted within "the relevant scientific community." The method's reliability must also be established, generally by a properly qualified expert.

If you read my blog post last week, you may be wondering how a novel technique like the fMRI could possibly meet that "general acceptance" standard.

Well, according to Ms. Murphy, the defense will argue that the "relevant scientific community" is a narrow group consisting only of scientists who research and develop fMRI-based lie detection. Tricky, huh? As Ms. Murphy comments:

Limiting the "relevant community" to only those who research and develop fMRI based lie detection is without merit, if only because such a definition precludes effective or sufficient peer-review. Indeed, it is arguable such a narrowly-defined community has a strong incentive to exaggerate its claims of accuracy and overlook unanswered questions for financial gain if such techniques are "legally admissible."

The few practitioners who research and develop fMRI-based deception detection are not the only qualified people to comment on the accuracy and validity of the technique. Statisticians familiar with Bayesian analysis, cognitive neuroscientists familiar with technical and analytical constraints, and researchers working to elucidate the neural basis of memory, decision-making, and social behavior should all make up the "relevant scientific community" for such a complex and as-yet poorly characterized technology. Further, I suspect the community of peer-reviewers that have reviewed the articles being proffered in support of the evidence of fMRI testing on deception is probably a useful proxy for the legally relevant scientific community, and extends well beyond the handful of researchers working directly on fMRI-based deception detection.

As to Murphy's last hope -- that journal peer reviewers could stand in for the legally relevant scientific community -- maybe that would help, and maybe it wouldn't. Remember, as I pointed out in last week's post, researchers at UC San Diego have found that the publishers of leading scientific journals are just as wowed by fMRI technology as everyone else, and they are uncritically promoting studies of questionable statistical merit.

To commercial ventures like No Lie MRI in California and its competitor, Cephos Corporation in Massachusetts, profit is the bottom line. Despite the controversy surrounding the reliability and validity of the lie detection technique, they are aggressively marketing the tools to clients and attempting to get them accepted in court.

Indeed, over at New York University's Scienceline, the president and chief executive of the eight-person start-up Cephos Corporation says he believes it it has a "strong possibility of being introduced as evidence" in court within the next couple of years.

Maybe sooner, depending upon the outcome of this case.

POSTSCRIPT: After opponents to the fMRI's introduction mounted a vigorous opposition and prepared to do battle at an evidentiary hearing, "the proponents of the evidence withdrew their request to have it admitted, thus ending the issue in [the] case," according to a March 25 letter from the San Diego County Counsel's Juvenile Dependency Division. Although fMRI proponents bowed out of this battle, we are sure to see more attempts to prematurely introduce brain scans as evidence in court in the coming months and years.

New book review in California Lawyer

My review of Charles Patrick Ewing's Trials of a Forensic Psychologist is now available online at the California Lawyer website. Here is how the review begins:

Billy Shrubsall was the top student at his small Niagara Falls, New York, high school. Thus, it came as a surprise when he didn't show up to give the 1988 valedictory address. But he had good reason. Just hours earlier, the 17-year-old had clubbed his domineering mother to death.

To explain Billy's horrific crime, his attorney advanced a theory of "psychological self-defense." The attorney retained forensic psychologist and attorney Charles Patrick Ewing, who had recently advanced the novel doctrine in his 1987 book Battered Women Who Kill (Lexington Books). Ewing's sympathetic testimony paved the way for a plea bargain under which Shrubsall served just 16 months in prison. A model prisoner and parolee, Shrubsall went on to graduate from an Ivy League university and become a Wall Street stock analyst.

But all was not as rosy as it appeared. The ostensibly rehabilitated and upright citizen still had a dark side as a vicious misogynist. He had been assaulting girls since his mid-teens, and a decade after his mother's death he brutally assaulted at least three women in Halifax, Nova Scotia. In one assault eerily reminiscent of his mother's beating death, Shrubsall clubbed a female store clerk with a baseball bat, shattering her skull.

Shrubsall's case is one of more than 600 in which Ewing has testified as an expert. But that case still haunts him, as he states in his latest book, Trials of a Forensic Psychologist: "[A]fter decades of working with the victims of violence and sexual abuse, I know all too well the awful harm Shrubsall did to the women he later victimized ... to this day when I testify as an expert, I am often questioned about my role in this case."

New York Times reports on Czech castration furor

Last month, I reported on the controversy in Europe over Czechoslovakia's castration of convicted sex offenders. Yesterday, the New York Times ran a feature report, excerpted here:

... Whether castration can help rehabilitate violent sex offenders has come under new scrutiny after the Council of Europe’s anti-torture committee last month called surgical castration “invasive, irreversible and mutilating” and demanded that the Czech Republic stop offering the procedure to violent sex offenders. Other critics said that castration threatened to lead society down a dangerous road toward eugenics.

The Czech Republic has allowed at least 94 prisoners over the past decade to be surgically castrated. It is the only country in Europe that uses the procedure for sex offenders. Czech psychiatrists supervising the treatment — a one-hour operation that involves removal of the tissue that produces testosterone — insist that it is the most foolproof way to tame sexual urges in dangerous predators suffering from extreme sexual disorders.

Surgical castration has been a means of social control for centuries. In ancient China, eunuchs were trusted to serve the imperial family inside the palace grounds; in Italy several centuries ago, youthful male choir members were castrated to preserve their high singing voices.

These days it can be used to treat testicular cancer and some advanced cases of prostate cancer.

Now, more countries in Europe are considering requiring or allowing chemical castration for violent sex offenders. There is intense debate over whose rights take precedence: those of sex offenders, who could be subjected to a punishment that many consider cruel, or those of society, which expects protection from sexual predators....

Beware "voodoo" brain science

A discussion among colleagues of a brain imaging study purporting to distinguish heterosexual from homosexual men prompted me to write on this topic. Perhaps even more controversial than categorizing sexual orientation, given the current legal climate, was the researchers' claim that their technique holds promise for identifying sexual deviants such as pedophiles and the those with sexual paraphilias.

Brain imaging is all the rage these days. The past decade has witnessed an explosion of interest in the fMRI, with literally thousands of studies, several new journals, and lavish federal funding and attention in the popular media. But some prominent neuroscientists express concerns about both the science and the ethics of fMRI research. Likening it to the old pseudo-science of phrenology, they caution that the public may be lured by vivid and colorful graphics into a misleading impression of scientific precision.

So, what is the fMRI?

Unlike the more established Magnetic Resonance Imaging (MRI) technique, which produces static images of the brain, the functional Magnetic Resonance Imaging (fMRI) provides images of the brain in action, or as it functions. The most widely used fMRI technique in cognitive neuroscience research is the BOLD (Blood Oxygen Level Dependent) method. This method is based on the premise that activation of specific brain regions affects blood flow and blood oxygenation, which can then be measured.

What does this have to do with forensics?

In the forensic arena, probably the most widely publicized research application of the fMRI is in the area of lie detection. fMRI data indicate that certain parts of people's brains -- specifically the anterior cingulate cortex and superior frontal gyrus -- are activated when they lie. But other studies show that the anterior cingulate activates during many other cognitive activities as well, indicating a lack of specificity that makes the technique inappropriate in the real world.

Other forensic applications include the hunt for the ever-elusive psychopath (the image at the left purports to show the brain of a psychopath in action). Some criminal defense attorneys also show fMRI images of their clients to jurors in an attempt to prove brain damage and thereby reduce their clients' legal culpability.

And, as I just said, researchers are starting to apply fMRI techniques to the study of human sexuality, including sexual orientation and sexual deviancy.

What are the problems?

Neuroscientist critics are issuing increasingly vocal alarm calls over both the underlying science and the practical applications of neuroimaging. Their central areas of concern include:

• The measurement techniques lack scientific precision
• Claims of scientific reliability and validity are overstated
• The fMRI overemphasizes brain localization when the brain functions more as a whole
• Applying group fMRI to individuals is improper at this stage of the science
• Marketing and forensic applications are ethically and philosophically problematic

Most recently, in a potentially landmark analysis, a group of psychologists based at the University of California at San Diego examined the analytical techniques used in 54 peer-reviewed fMRI brain-scanning studies published in prominent scientific journals. They concluded that the methods used in half the studies were so "seriously defective" that the findings "should not be believed."

Lead researcher Harold Pashler went so far as to call the statistical methods "voodoo" that should be especially shunned in the forensic arena:

"In the law, individual differences are the main focus," the Wall Street Journal quoted Pashler as saying. "And it often could come down to these voodoo statistics."

The article, "Puzzlingly High Correlations in fMRI Studies of Emotion, Personality,
and Social Cognition" (originally titled "Voodoo Correlations in Social Neuroscience") will be published in a forthcoming issue of the Association for Psychological Science's journal Perspectives in Psychological Science. Reports the abstract:

"Functional Magnetic Resonance Imaging studies of emotion, personality, and social cognition have drawn much attention in recent years, with high-profile studies frequently reporting extremely high (e.g., >.8) correlations between behavioral and self-report measures of personality or emotion and measures of brain activation. We show that these correlations often exceed what is statistically possible assuming the (evidently rather limited) reliability of both fMRI and personality/emotion measures. The implausibly high correlations are all the more puzzling because method sections rarely contain sufficient detail to ascertain how these correlations were obtained. We surveyed authors of 54 articles that reported findings of this kind to determine a few details on how these correlations were computed. More than half acknowledged using a strategy that computes separate correlations for individual voxels, and reports means of just the subset of voxels exceeding chosen thresholds. We show how this non-independent analysis grossly inflates correlations, while yielding reassuring-looking scattergrams. This analysis technique was used to obtain the vast majority of the implausibly high correlations in our survey sample. In addition, we argue that other analysis problems likely created entirely spurious correlations in some cases. We outline how the data from these studies could be reanalyzed with unbiased methods to provide the field with accurate estimates of the correlations in question. We urge authors to perform such reanalyses and to correct the scientific record."
