““The mechanisms that form our perceptions operate almost entirely below the level of conscious awareness; ironically, we cannot sense how we sense. (...) Because we can't perceive these processes in action, and thereby take note of the places where error could enter the picture, we feel that we cannot be wrong. Or, more precisely, we cannot feel that we could be wrong. Our obliviousness to the act of interpretation leaves us insensitive - literally - to the possibility of error.””
