Another scientific study proves that water is wet. First it was atheists tend toward autism and now...

...people who tend to be utilitarian in solving moral dilemmas tend toward anti-social personalities.

These results (which recently appeared in the journal Cognition) raise questions for psychological theories of moral judgment that equate utilitarian responses with optimal morality, and treat non-utilitarian responses as moral "mistakes". The issue, for these theories, is that these results would lead to the counterintuitive conclusion that those who are "optimal" moral decision makers (i.e., who are likely to favor utilitarian solutions) are also those who possess a set of traits that many would consider prototypically immoral (e.g., the emotional callousness and manipulative nature of psychopathy and Machiavellianism).

Jeepers, who would have thought that people who decide the answer to moral questions based on a cold-hearted analysis of the best outcome could possibly be cold-hearted people who analyze everything in terms of outcomes?

Score another one for Aristotle and his idea that actions shape habits and habits shape personality and personality shapes destiny.
