Stronger conservatism (versus liberalism) was associated with less neurocognitive sensitivity to response conflicts. At the behavioral level, conservatives were also more likely to make errors of commission. Although a liberal orientation was associated with better performance on the response-inhibition task examined here,..snip"

Sulloway, a researcher at UC Berkeley's Institute of Personality and Social Research who was not connected to the study, said the results "provided an elegant demonstration that individual differences on a conservative-liberal dimension are strongly related to brain activity."
Analyzing the data, Sulloway said liberals were 4.9 times as likely as conservatives to show activity in the brain circuits that deal with conflicts, and 2.2 times as likely to score in the top half of the distribution for accuracy
