Shankar Vedantam is back, reporting on interesting research on how misinformation may still have an effect after it's corrected. I'm dubious of the reported difference between conservatives and liberals in this regard--my beginning position is they're both human, and both would operate similarly: i.e, my enemy is a bad, misinformed, lying s.o.b. But it does make one think, particularly someone who is as into politics as I am. One reason I do try to somewhat balance the blogs I read, despite the dangers to my blood pressure.
