Slate on the Neuropolitics 0p-Ed

Daniel Engber at Slate addresses the Iacobani, Freedman, et al. op-ed in the Sunday New York Times.  Here are a couple of excerpts, including some interesting links and a reference to this blog:

As the authors of what is essentially an extended FKF advertorial, Freedman and his colleagues have a strong incentive to tout their services and sex up the findings. Even so, many of their conclusions seem either haphazard or comically vague. Take their first point: When test subjects were shown the name of a political party—either the words Republican, Democrat, or Independent—they responded with neural activity in the amygdala, the insula, and the striatum. According to the authors, these regions of the brain correspond to feelings of anxiety, disgust, and pleasure. Really, all three? From that meaningless mishmash of emotions, they meekly conclude that "voters sense both peril and promise in party brands."

. . .

So, the study's findings aren't believable on their own terms. Take a step back, and there may be more fundamental problems. At the Neuroethics and Law Blog, cognitive neuroscientist Martha Farah tweaks the FKF team for assuming that activity in a given brain region always reflects the same emotional state. When subjects looked at photos of Mitt Romney, they showed increased blood flow to the amygdala—which the researchers interpreted here and elsewhere as a sign of anxiety. That's not necessarily true: The amygdala can also light up during the experience of anger, happiness, or sexual arousal.

Why has the New York Times proved so willing to donate its column space to this private company and its sloppy experiments? Perhaps the paper's editors have fallen prey to what psychologist Frank Keil calls the "illusion of explanatory depth." As Keil has shown in his own research, even gazing dumbly at a picture of the brain makes us feel as though we're deepening our understanding of the human mind. The fMRI scans published on Sunday, and the largely unsurprising findings they are meant to support, reveal the strength of this illusion.
