Who is To Blame? Partisans’ Use of Blame Spreading in Reaction to Unfair or Dishonest Behavior

Blame attribution research suggests partisans acknowledge evidence that portrays copartisans negatively but blame externalities for negative events. This study identifies another blame attribution pattern. When people observe unfair/dishonest behavior by a copartisan, instead of shifting blame entirely to others, they engage in blame-spreading. I conduct two tests: a survey of undergraduate students who watched part of a 2020 Presidential debate and a survey experiment of a random sample of adults that randomizes the party affiliation of the debate participant engaging in unfair/dishonest behavior. When the unfair actor is a copartisan, people blame both participants equally. When the unfair actor is in the out-party, people blame the out-party actor. These findings suggest individuals acknowledge undesirable behavior among copartisans, but seek to justify it by identifying blame-worthy behavior by others, thus providing an additional mechanism in motivated reasoning whereby individuals acknowledge events while finding a way to justify such behavior.
