Emory University psychologist Drew Westen put self-identified Democratic and Republican partisans in brain scanners and asked them to evaluate negative information about various candidates. Both groups were quick to spot inconsistency and hypocrisy -- but only in candidates they opposed.
When presented with negative information about the candidates they liked, partisans of all stripes found ways to discount it, Westen said. When the unpalatable information was rejected, furthermore, the brain scans showed that volunteers gave themselves feel-good pats -- the scans showed that "reward centers" in volunteers' brains were activated. The psychologist observed that the way these subjects dealt with unwelcome information had curious parallels with drug addiction as addicts also reward themselves for wrong-headed behavior.

That study found that supporters of President Bush and other conservatives had stronger self-admitted and implicit biases against blacks than liberals did.
"What automatic biases reveal is that while we have the feeling we are living up to our values, that feeling may not be right," said University of Virginia psychologist Brian Nosek, who helped conduct the race analysis. "We are not aware of everything that causes our behavior, even things in our own lives."
Brian Jones, a spokesman for the Republican National Committee, said he disagreed with the study's conclusions but that it was difficult to offer a detailed critique, as the research had not yet been published and he could not review the methodology. He also questioned whether the researchers themselves had implicit biases -- against Republicans -- noting that Nosek and Harvard psychologist Mahzarin Banaji had given campaign contributions to Democrats.
