Abstract:
|
Does order matter? Studies have found that going first or last in a sequential order contest leads to a biased outcome, commonly called primacy and recency. This study tests for those biases and two other forms: sequential bias and difficulty bias. We confirm previous work, finding that it is valuable to go later in the competition. We find no evidence of sequential bias, meaning one person's score is unrelated to the previous person's score. Finally, we find strong evidence of difficulty bias. Contestants who attempt higher difficulty increase their execution score, even when difficulty and execution scores are judged separately.
