Game Theory and Applications

Group influence on risk taking was studied in a realistic casino setting, using blackjack as the criterion risk task and amount bet as the risk measure. State trial judges from around the nation volunteered to serve as participants and bet their own money. The results clearly reveal a shift to risk and replicate findings from prior blackjack studies which had used college students as subjects and gaming chips of no real monetary value. Specifically, a modest increase in risk levels over time was found for individuals before they entered into group play; and a strong increase in risk levels was obtained during subsequent group play. These findings were accounted for by Blascovich and Ginsburg's two-process model.
