I meant that it's the specific underlying mechanisms that can produce a bias or promote correctness; a bias is just a surface level fact about what errors people tend to make. Also, lots of biases are specific to a certain mental task and cannot be interpreted in foreign contexts. It's not guaranteed either that a current "bias" concept will not be superseded by additional knowledge. Therefore, the ideal basis of debiasing is most likely a detailed understanding of psychology/neurology; which is a point you expressed, and I agree.
