Hindsight bias is the mistaken belief that an outcome could have been foreseen once it is known. But what happens after learning about an event? Can reading biased media amplify hindsight distortions? And do people from different cultural backgroundswith different cognitive thinking stylesdraw equal conclusions from equal media reports? We report two studies with Wikipedia articles and samples from different cultures (Study 1: Germany, Singapore, USA, Vietnam, Japan, Sweden, N = 446; Study 2: USA, Vietnam, N = 144). Participants read one of two article versions (foresight and hindsight) about the Fukushima Nuclear Plant and estimated the likelihood, inevitability, and foreseeability of the nuclear disaster. Reading the hindsight article increased individuals' hindsight bias independently of analytic or holistic thinking style. Having excluded survey language as potential impact factor (Study 2), this result remains. Our findings extend prior research on hindsight bias by demonstrating the amplifying effect of additional (biased) information on hindsight bias.
