In a new study in the Proceedings of the National Academy of Sciences, scientists Joshua Greene and Joseph Paxton tried to determine whether honesty was a conscious process—something we can control—or whether it was something we couldn’t control, something that occurred automatically.
From Seed Magazine: “What they found is that honesty is an automatic process—but only for some people. Comparing scans from tests with and without the opportunity to cheat, the scientists found that for honest subjects, deciding to be honest took no extra brain activity. But for others, the dishonest group, both deciding to lie and deciding to tell the truth required extra activity in the areas of the brain associated with critical thinking and self-control.”
Hm. My next thought after reading this was this: Which group would fiction writers, who lie and tell the truth at the same time, fall into? And then my head exploded. (via)
