My research is focused on the interrelationship between advice giving, decision support, altruism and helping behavior. Specifically, I study the unexplored topic of giving costly advice. I suggest that advice-giving, like altruistic punishment, leads to cooperation and efficient social outcomes. Therefore, my hypothesis is that people will elect to give helpful information to others, even at a material cost to themselves. I investigate this and other hypothess through lab experiments and questionnaires in our "Charming Lab". In addition, I'm collaborating with my advisor Prof. Ilan Yaniv, and with my colleague Maxim Milyavsky, on projects investigating advice-taking behaviors, such as our recent work on people's over-confidence in judgments that are based on consensual, interdependent opinions.
