Supplementary material from "Polarized imagination: partisanship influences the direction and consequences of counterfactual thinking"

Four studies examine how political partisanship qualifies previously documented regularities in people's counterfactual thinking (N = 1186 Democrats and Republicans). First, whereas prior work finds that people generally prefer to think about how things could have been better instead of worse (i.e. entertain counterfactuals in an upward versus downward direction), Studies 1a–2 find that partisans are more likely to generate and endorse counterfactuals in whichever direction best aligns with their political views. Second, previous research finds that the closer someone comes to causing a negative event, the more blame that person receives; Study 3 finds that this effect is more pronounced among partisans who oppose (versus support) a leader who ‘almost' caused a negative event. Thus, partisan reasoning may influence which alternatives to reality people will find most plausible, will be most likely to imagine spontaneously, and will view as sufficient grounds for blame.This article is part of the theme issue ‘Thinking about possibilities: mechanisms, ontogeny, functions and phylogeny’.
