Bias Blind Spot (BBS) is the phenomenon that people tend to perceive themselves as less ‎susceptible to biases than others; these authors could replicate the original findings

Description: Bias Blind Spot (BBS) is the phenomenon that people tend to perceive themselves as less ‎susceptible to biases than others. In three pre-registered experiments (overall N = 969), we ‎replicated two experiments of the first demonstration of the phenomenon by Pronin, Lin, and ‎Ross (2002). We found support of the BBS hypotheses, with effects in line with findings in the ‎original study: Participants rated themselves as less susceptible to biases than others (d = -1.00 ‎‎[-1.33, -0.67]) and as having fewer shortcomings (d = - 0.34 [-0.46, -0.23] with differences ‎between effects: d = -0.43 [-0.56, -0.29]). Extending the replications, we found that beliefs in ‎own free will were positively associated with BBS (r ~ 0.17-0.22) and that beliefs in both self ‎and general free will were positively associated with self-other asymmetry related to personal ‎shortcomings (r ~ 0.16-0.24).
