Abstract
The storming of the US Capitol on January 6, 2021, and voter intimidation by Donald Trump’s supporters have marked significant upheaval in American democracy. In two cross-sectional studies and one experiment, we tested the proposition that American collective narcissism is associated with support for populist leadership (particular, their message of renewed ingroup recognition) to the point of disregard for democratic procedures. In Study 1, conducted just before the 2020 presidential elections, we examined the association of American collective narcissism with support for Trump’s re-election even if he was to violate the democratic procedures while securing it. In pre-registered Study 2, conducted just after the Capitol attack, we examined the association between American collective narcissism and support for the attacks. In Study 3, we experimentally examined a more general proposition that collective narcissism is associated with support for populist leaders and lack of support for democratic procedures, in a minimal group setting deprived of any associations with a particular political context. The results of the three studies converge to indicate that collective narcissism is most strongly (beyond variables commonly implicated in support for right-wing populism) associated with populist leadership to the extent of disregarding democratic norms.
