ddobbs | May 12, 2009Most of us recognize the power of the urge to conform , but you don't often see it evoked and displayed so starkly as in this old Candid Camera segment. The CC crew seeds an elevator with several crew members who do odd things like face the rear of the elevator car. See how long the naive bystanders who join them hold out against the pressure.
-- Whu-oh: This is where missing video was --
update: Posted here was a wonderful segment as described above. I had found it via Google Video. It was up about 3 hours when I got an email from someone claiming to be from Candid Camera, Inc., asking me…
ddobbs | April 29, 2009Amid my flu frenzy I missed Vaughn Bell's excellent consideration of CIA psychology through the declassified memos:
I've been reading the recently released CIA memos on the interrogation of 'war on terror' detainees. The memos make clear that the psychological impact of the process is the most important aim of interrogation, from the moment the detainee is captured through the various phases of interrogation.
Although disturbing, they're interesting for what they reveal about the CIA's psychologists and their approach to interrogation.
As Vaughn notes,
A couple of the memos note that the…
ddobbs | April 28, 2009Leave it to Vaughn Bell to find this stuff: emotional maps of different cities. Got to get a hold of this -- and as Vaughn explains, you and I can, with free download. (But leave the author some $. It's the right thing to do.)
Nold came up with the idea of fusing a GSR machine, a skin conductance monitor that measures arousal, and a GPS machine, to allow stress to be mapped to particular places. He then gets people to walk round and creates maps detailing high arousal areas of cities.
The biomapping website has some of the fantastic maps from the project.
His book, called Emotional…

ddobbs | April 20, 2009Who stands most at risk of PTSD? A new study of PTSD in US veterans of the current Iraq and Afghanistan wars suggests that you can identify the most vulnerable -- soldiers who stand 2 to 3 times the risk of their peers -- with fairly simple measures of mental and physical health.
The study, conducted by the U.S. Navy's Tyler Smith and collegues, is part of an ongoing longitudinal study of over 150,000 U.S. soldiers. The Millennium Cohort Study began collected comprehensive health data on U.S. soldiers in 2001. This study draws on that data to compare health status before deployment to Iraq…
ddobbs | April 18, 2009Vaughn Bell, looking at the recent reports on torture, finds unsettling information about the participation of psychologists and physicians:
The Washington Post has an article exploring recently released 'war on terror' interrogation memos, showing that "psychologists, physicians and other health officials" played a key part in interrogations widely condemned as torture.
It's an interesting revelation because during the long debates, and some say heal-dragging, over whether the American Psychological Association should ban its members from participation, one of their main arguments was that…

Robots as recruitment to science.

ddobbs | April 10, 2009Via Tyler Cohen's Marginal Revolution comes this amusing anecdote -- and, perhaps, helpful example -- from the life of Peter Orszag, Obama's very brainy budget director. To motivate himself to train for a marathon, he somehow set up a penalty if he didn't hit his training targets: His credit card would make a contribution to a charity or cause he hated:
]"If I didn't achieve what I wanted to, a very large contribution would automatically come out of my credit card and go to a charity that I very much didn't support," Orszag says of his training strategy. "So that was a very strong motivation…
ddobbs | April 8, 2009When you propose that we are overdiagnosing PTSD in vets, you run into not only a lot of flak but many offerings of evidence suggesting that we're missing a lot of cases. Since publishing my article on PTSD, I've received those arguments directly in comments, and on Wednesday, April 8, Salon published an article, "I am under a lot of pressure to not diagnose PTSD," by Michael de Yoanna and Mark Benjamin, that offers unsettling evidence that at least some doctors working for the VA are being pressed to not diagnose PTSD in combat vets.
So which is it? Are we under- or overdiagnosing PTSD in…
ddobbs | April 8, 2009More or less alongside my piece on depression's wiring diagram, this months' Scientific American Mind has a piece I wrote on how social hierarchies develop among rats.
Darlene Francis, a psychologist at the University of California, Berkeley, placed 80 newly weaned rats in cages of four, with cage mates matched for size, activity level and early life environment. To Francis's amazement, it took weeks--until the rats were well past puberty--for a social hierarchy to evolve (as indicated by which mouse got first dibs at food and water, among other measures). Perhaps more surprising was that…
ddobbs | March 23, 2009I've had mixed reactions to Gladwell's writing over the years: I always enjoy reading it, but in Blink, especially, when he was writing about an area I knew more about than in his other books, I was troubled not just by what seemed an avoidance of neuroscientific explanations of attention and decision-making, but by an argument that seemed to come down to "The best way to make decisions is the quick gut method, except when it's not." I was also troubled by ... well, I couldn't put my finger on it. But Joseph Epstein has:
Too frequently one reads Gladwell's anecdotes, case studies, potted…
ddobbs | March 20, 2009A few weeks ago, Matt Stevens, the National Guard captain and medic who served in Iraq and whom I mentioned in my Scientific American article, "The Post-Traumatic Stress Trap, wrote me an email about the social unease he often encountered when he showed any behavior that might remind people he had served in Iraq -- a greater seriousness, an impatience with petty concerns or inefficiency, or even just talking about the place.
I have begun to think of military PTSD as to some extent a civilian problem rather than a soldier problem. To expand slightly here; civilians/politicians send soldiers…
ddobbs | March 16, 2009Below are materials supplementing my story "The Post-Traumatic Stress Trap," Scientific American, April 2009. (You can find the story here and my blog post introducing it here.) I'm starting with annotated sources, source materials, and a bit of multimedia. I hope to add a couple sidebars that didn't fit in the main piece -- though those may end up at the main blog, so you may want to keep an eye there or subscribe via RSS or Atom.

ddobbs | March 14, 2009
My story in the April 2009 Scientific American story, "The Post-Traumatic Stress Trap", just went online. Here's the opening:
In 2006, soon after returning from military service in Ramadi, Iraq, during the bloodiest
period of the war, Captain Matt Stevens of the Vermont National Guard began to have a problem with PTSD, or post-traumatic stress disorder. Stevens's problem was not that he had PTSD. It was that he began to have doubts about PTSD: the condition was real enough, but as a diagnosis he saw it being wildly, even dangerously, overextended.

ddobbs | March 10, 2009"How We Decide" author Jonah Lehrer, fresh from a book tour of the UK, offers what he calls a "spluttering answer" (it's really quite lucid) to a question he says he's getting a lot these days: What decision-making errors were involved in our current financial meltdown??
The short version of his answer -- well worth reading in its entirety -- is that we (and big investment outfits particularlyl) succumbed to an abhorrence of uncertainty.
We hate not knowing, and this often leads us to neglect relevant information that might undermine the certainty of our conclusions. I think some of the…
ddobbs | March 10, 2009Back in October a study found that high testosterone levels were associated with higher levels of financial risk-taking. Now comes the blowback, as Andrew Sullivan notes:
Tina Beatie attacks testosterone:
...it is interesting to note that Pope Benedict has recently suggested that there is a close connection between original sin and the greed that has created the current economic crisis. It is also notable that the credit crunch has been created by a profession that is almost exclusively male. In the line-up of failed bankers, not a single woman's name has appeared. Male greed has proven…

ddobbs | March 6, 2009Ezra Klein reviews Obama's handling of yesterday's health summit -- a piece well worth reading for a taste of how sharply focused and serious Obama is about truly comprehensive health-care reform.
Karen Tumlty, a health-care expert, describes in Time her own family's grueling wrestling match with the health-insurance industry. A timely story -- no pun intended -- as it makes painfully clear that it's not just the 46 million people uninsured (did I just say "just" 46 million people) who fare poorly in the current system.

ddobbs | March 5, 2009Philip Dawdy takes a interesting look at a new study of the safety of placebo arms in clinical trials of antidepressants in teens. My own quick scan of the study [which Dawdy makes available as pdf download] suggests it's full of great nuggets.
Its take-home: Placebo treatments produced remission rates of 48%, while the rate for active treatment was 59%. And, quite interestingly, the study concludes:
Patients who responded to placebo generally retained their response. Those who did not respond to placebo subsequently responded to active treatment at the same rates as those initiallyl…
