Male sports fans (N = 74) were asked to estimate the likelihood that they w
ould intervene in a crowd disturbance in an attempt to stop the fighting. T
hey also completed a battery of measures that included their attitude towar
d law and order, fight history, the false consensus effect, impulsivity, ps
ychopathy, sensation seeking, anger, physical aggression and identification
with their favorite team. Law and order, body mass, anger and the false co
nsensus effect were positively related to peacemaking whereas sensation see
king was negatively related. A multiple regression analysis yielded a solut
ion that accounted for 32.3% of the variance with anger and attitude toward
law and order emerging as the best predictors.
