Common sense says its easy to be honest than trying to weave stories to cook up a lie. Yes, neuroscience now vindicates that common sense (duh!!). Earlier post on the same here.
Here is Joshua Greene's last year report (thanks):
"Using neuroimaging, psychologists looked at the brain activity of people given the chance to gain money dishonestly by lying and found that honest people showed no additional neural activity when telling the truth, implying that extra cognitive processes were not necessary to choose honesty. However, those individuals who behaved dishonestly, even when telling the truth, showed additional activity in brain regions that involve control and attention.
Being honest is not so much a matter of exercising willpower as it is being disposed to behave honestly in a more effortless kind of way, says Greene. This may not be true for all situations, but it seems to be true for at least this situation."
