Popis: Objectives: Previous studies have shown that sport officials’ decisions can be impacted by biases associated with expectations. The aim of this study was to determine whether elite cricket umpires’ decisions are also influenced by expectations associated with batter skill. Methods: LBW decisions (n = 5578) from actual elite level cricket matches in Australia between 2009 and 2016 were analysed in a multi-level binomial logistic regression paradigm. In our first model, we predicted the likelihood that an umpire will answer ‘out’ for batters in the top order (1–4), middle order (5–7), and low order (8-11). In our second model, we controlled for the correctness of a decision. Results: Umpires were more likely to respond ‘out’ as the batting order progressed, however this did not appear to be due to biased decision-making. Instead, as batting order progressed, batters were more likely to actually be ‘out’. Conclusions: Cricket umpires do not seem to be impacted by expectation bias associated with batting order. This study highlights the importance of controlling for the correctness of a decision when exploring bias in sport officials’ decisions.
