Rigged card game 'Swap' sheds light on perceptions of inequality - ScienceBlog.comRegardless of how many cards were exchanged and which version they played, winners were twice as likely as losers to describe the game as fair. When cards were exchanged to favor the winner, however, winners found the game less fair – an effect that became more pronounced when two cards per round were traded. In fact, the winners’ perceptions of the game’s fairness declined more sharply than losers’ as their advantage increased – “indicating that winners’ perceptions are more sensitive than losers’ to a system that is rigged in their favor,” according to the paper. Researchers termed this the “Warren Buffett effect,” because Buffett and some other billionaires advocate to pay higher taxes. “A possible reading of our results is that winners want the playing field to be tilted enough to guarantee the outcome but not so much that the game appears hopelessly rigged in their favor,” Macy said.
