> Any advice that you both understand and fits perfectly into your mental model is probably coming from whatever dogma you already follow

I don't know what you mean by "fits perfectly" into one's mental model, but one can certainly accept new information validated against their own understanding of the world. People don't put an equal amount of weight in each of their beliefs and there are axiomatic ones that can be used in logical arguments to disprove the inconsistencies of others.
