Extending the argument engagement model

Abstract

This investigation considers the factors that predict the intent to engage in interpersonal arguments. By adapting the argument engagement model (Hample, Paglieri, and Na 2012), a subjective expected utility model was tested to determine the effects of (1) evaluative assessments, in addition to probabilistic assessments, and (2) probabilistic assessment-trait interactions on argument engagement. Participants (N = 273) read three argument vignettes and answered questions about their intent to argue in each situation. Results were mixed regarding the significance of expected values and situation-trait interactions in predicting intentions to argue. Participants overwhelmingly reported an optimism bias, whereby they tended to perceive positive outcomes of argument as likely and negative outcomes of argument as unlikely. Possible reasons for these findings and their implications are discussed.
