At Duke, I was fortunate to be advised by Dan Ariely, the brilliant behavioural economist dedicated to understanding why it is that people make "predictably irrational" decisions. As a member of the Center for Advanced Hindsight (CAH), my doctoral research explored when, how and to what extent social and cultural factors influence our decisions about whether to be honest. I worked with terrific research collaborators, and together we found:
- Evidence that lying tendencies are related among friends and family members.
- Evidence that, in contrast to predictions, people’s basic tendencies toward dishonesty are quite similar across countries that differ in corruption and cultural values.
- Evidence that dishonesty is expressed differently in different domains of life (such as work, relationships, religion, etc.)
- Evidence that feelings of guilt are stronger deterrents of dishonest behavior than legal penalties.
- Evidence that we hold members of our own social group to lower moral standards than members of an opposing social group (although we believe our moral standards are consistent).
