A *null* result I'm very proud of! Led by Rustam Romaniuc, 35 coauthors from all over France tested nudge interventions to boost voter turnout. None worked, and we are possibly not surprised -- but a well-powered null result *is* a result! Paper: kwnsfk27.r.eu-west-1.awstrack.me/L0/https:%2F...
For a quick introduction to this research, see the post below. Full working paper/pre-print: osf.io/preprints/ps...
Our new research finds that people are willing to cheat if it benefits their group — even when they gain nothing themselves. "the risk of dishonesty in organizations is not limited to selfish acts...employees might bend rules to benefit their team or in-group members." www.nhh.no/en/nhh-bulle...
Pre-print: osf.io/preprints/ps... Abstract and key figure summarizing the main effect across our three experiments: See below. As always: Feedback is most welcome.
Can the psychology of time help us understand climate change? In collaboration with my excellent PhD student Simen Bø, we have a new pre-print exploring the temporal psychology of climate hesitancy, and whether it is possible to increase actual climate support by varying the *timing* of incentives.

Do people lie to benefit the in-group and harm the out-group? In a new paper, we found that people lied 9% more to help in-group members than out-group members! This is evidence of coalitional dishonesty Democrats & Republicans both lied anonymously to double in-group members earnings (N=5,230)
We have a new working paper, studying planning choices in the United States and Tanzania: "Just perfect days ahead?" Documenting a robust best-case planning tendency, see below for details! Joint work with my last-year PhD student Simen Bø and Vincent Somville.

Three experiments with more than 5,000 participants show that people are willing to cheat if it benefits their group — even when they gain nothing themselves.

We lie for those who are like us
