All four biases were prevalent in the results, but we found no consistent relationships with cognition (cognitive style, cognitive reflection). Our sample included both novice and expert forecasters. They did not differ significantly in their susceptibility to biases. The lack of individual differences in bias susceptibility suggests that universal approaches to debiasing are possible.enBiasesCognitive StylesForecastingIndividual DifferencesJudgmentApplied Cognitive Psychology35909
