In May, I earned my PhD in Psychology from Duke University, where I've been conducting my doctoral research with Dan Ariely. As a member of the Center for Advanced Hindsight, I have learned how tell compelling stories, how to play excellent April fools pranks, and how to saber a champagne bottle – and learned a lot about behavioural economics, too!
Behavioural economics brings our understanding of psychology and behaviour to bear on economic decision-making. Together with terrific research collaborators, I have explored how social and cultural factors influence decisions about whether or not to be honest.
- 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).
