This tendency resembles a self-enhancement ef fect, but research has mainly focused on other mechanisms that purported ly underlie the BBS. In this article we present developmental evidence that the BBS and a self-enhancing tendency, namely the better-than-average ef fect, develop independently (Studies 1 and 2). Children aged 5 to 12 years old do not believe they are biased (despite evidence that they are). How ever, while younger children tend to believe others are unbiased, older children believe others are biased (Studies 2 and 3). Importantly, younger children understand that unbiased behavior is better than biased behavior (Study 4). Together, these results converge with the notion that the BBS is not a mere instance of a self-enhancing tendency and suggest that the BBS is the residual part of a bigger illusion that everyone is unbiased.engBias blind spotBetter than averagePerson perceptionBiasSocial cognitive developmentjournal article2024-02-07cv-prod-125287210.1521/soco.2018.36.6.6712-s2.0-85061991146
