Each item describes a bias and participants rate the extent to which they exhibit that bias and the extent to which the average American exhibits that bias on 7-point scales with endpoints, not at all (1) and very much (7).
Bias blind spot scores are calculated by subtracting the perceived self-susceptibility to each bias from the perceived susceptibility of the average American to that bias, for each bias, and then by averaging those relative differences.
