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).
