Belief Bias is the tendency to judge the strength of arguments based on the plausibility of their conclusion rather than how strongly they support that conclusion. Logic is sometimes put to one side and the strength of an argument is down to what is believed to make more sense.
A useful counter-measure is to ask yourself: How much of my conclusion is being structured by a pre-existing decision I’ve made or something I believed in from the past? Without that influence, would my decision or thought be the same?
