Liberals are smarter, except when circumstances call for a knee-jerk ideologue.

A study says liberal brains "are more responsive to informational complexity."

Test: You sit in front of a computer screen and wait for a letter to appear on it. You're supposed to tap your keyboard if it's an M, but not if it's a W. The experimenters mix it up but give you more M's than W's to see whether you get lulled into tapping when you shouldn't.

Results:

1) On M's, liberals and conservatives responded equally well.

2) On W's, liberals were twice as likely to be among the more accurate responders.

3) On electrical measurements of the brain area that monitors conflict "between a habitual tendency … and a more appropriate response," liberals were five times more likely to show brain activity.

Unofficial scientist/media spin: Liberals are smarter.

Knee-jerk liberal spin: We're smarter because we have more agile brains.

Thoughtful liberal spin: Then again, maybe we have more agile brains because we're smarter.

(Human Nature's view: Liberals are smart, except when their knees jerk.)
