They discovered, as expected, that people initially had a strong emotional and neurological response to lying; but as they continued to lie, they felt less and less emotional response (flushed cheeks, racing heart) and, accordingly, their brains’ amygdalae responded less and less.
The study is especially interesting because the participants’ brains were reacting not to conditions outside their control, but to their own free choices. So, yes: Lying gets easier with practice.
It’s hard to know what to say about a study like this, other than, “Well, duh.” The Church already has a word for this phenomenon — and a cure, as well.
