Self-related motivational aspects of hindsight bias in soccer athletes

Purpose Hindsight bias is known to hinder people from learning and make people too adventurous in future decisions. The influence of hindsight bias on athletes, however, has not been widely and extensively investigated. Thus, the purpose of this study is to examine self-related motivational aspects of hindsight bias in a sports context. Method Questionnaires were completed by 84 soccer players in a retrospective-design study. Respondents were divided into winning team members vs. losing team members and playing members vs. nonplaying members to assess the culpability for a negative outcome and outcome controllability. Results Two-way repeated-measures ANOVA revealed significant hindsight bias for the expected match score regardless of team and player factors. In terms of player factors, playing members of the losing team and nonplaying members of the winning team increased their confidence levels for the expected match score. In terms of team factors, winning team members increased their confidence levels for the expected winning team. The reverse was true for losing team members. Conclusions Playing members of a losing team used retroactive pessimism and showed greater hindsight bias. Winning team members showed greater hindsight bias, consistent with previous findings that people show hindsight bias for their own good performances. The results are further discussed in light of outcome controllability, expertise, and disappointment.
