This study examined associations among adolescent risk preference and political engagement using nationally representative Monitoring the Future data from high school seniors (N=109,574; modal age=18 years) spanning 1976-2014. Greater risk preference was associated with greater past voting, donating to a campaign, writing government officials, boycotting, and protesting. Greater risk preference was associated with higher future intentions to boycott and protest, but lower intentions to donate to or volunteer for a campaign. In general, associations between risk preference and political engagement became stronger with higher levels of political interest. Results highlight the importance of considering the adaptive role of adolescent risk preference and suggest that political engagement may be a constructive outlet for youth who pursue or are comfortable taking risks.
