Risk Taking And Party Affliation

Matt Yglesias links to a paper that examined brain functions during risk taking and correlated it with political party affiliation:
Amygdala activations, associated with externally directed reactions to risk, are stronger in Republicans, while insula activations, associated with internally directed reactions to affective perceptions, are stronger in Democrats. These results suggest an internal vs. external difference in evaluative process that illuminates and resolves a discrepancy in the existing literature.

FLG isn't quite sure yet how this jibes with his Time Horizons Theory (C), but this passage catch his eye because he thinks it explains the paper better than the excerpt above:
Thus, it appears in our experiment that Republican participants, when making a risky choice, are predominantly externally oriented, reacting to the fear-related processes with a tangible potential external consequence. In comparison, risky decisions made by Democratic participants appear to be associated with monitoring how the selection of a risky response might feel internally.
