My talk on "What really motivates people to be honest in business" is featured on TED.com.
In Gibson, Tanner and Wagner (AER 2013), we introduce the protected values scale in economics (drawing on work in psychology) and show that people with stronger protected values resist incentives to lie. The protected values scale used for the task at hand is here.
This paper shows that social norm-based interventions work --- but that different people react very differently.
We find that trade-off resistance is also reflected in brain activity.
