Bias

Shankar Vedantam reports in the Post:

A new study by researchers at Massachusetts General Hospital and other institutions affiliated with Harvard University provides empirical evidence for the first time that when it comes to heart disease, bias is the central problem -- bias so deeply internalized that people are sincerely unaware that they hold it.

Physicians who were more racially biased were less likely to prescribe aggressive heart-attack treatment for black patients than for whites. The study was recently published in the Journal of General Internal Medicine.

The research finding cannot be automatically extrapolated to the NBA or other domains, but it does suggest a mechanism by which disparities emerge. No conscious bias was apparently present -- there was no connection between the explicit racial views of physicians and disparities in their diagnoses. It was only when researchers studied physicians' implicit attitudes -- by measuring how quickly they made positive or negative mental associations with blacks and whites -- that they found a mechanism to explain differences in medical judgment.

Since the Pigford/USDA bias issue last week, I seem to be running into bias and race. I think this is about right. In our rational calculating side, most people aren't biased on most things. But it's the snap stuff that trips us up. (Going back to the article, I think Jerome Groopman in his recent book reported on a study that showed that physicians typically interrupted their patients with x seconds--they were leaping to conclusions, most of the time correctly, but not always.)
