It is my impression that people generally have an epistemic distortion already and Alicorn's advice would help them overcome it. When we justify our own actions, we place a weight on circumstances and give ourselves a fair benefit of the doubt. When we look for the reasons for other people's actions we often do not know, care to know or just plain care about what the circumstances were. No benefit of the doubt here. Reversing this bias seems a good and healthy thing to do. Judge others as you would judge yourself may sound simple but it takes the sort of persistence that Alicorn outlines.
