From the November issue of Harper’s:

Scientists announced that conservatives and liberals have different patterns of neuronal impulses when confronted with unexpected circumstances.  Self-described conservatives pressed the wrong button in response to a new stimulus 47 percent of the time, whereas avowed liberals had a 37 percent error rate; liberals had double the activity of conservatives in the anterior cingulate cortex, a deep region of the brain that helps people recognize “no-go” situations, but the study’s authors emphasized that the results do not mean that liberals are smarter or better than conservatives.

Dear authors of the study, I understand why you’d play it safe and issue that disclaimer at the end.  We know (wink, wink) what the results mean, though, don’t we?
