Personally, I’ve gotten so that I now use a kind of two-track analysis. First, what are the factors that really govern the interests involved, rationally considered? And second, what are the subconscious influences where the brain at a subconscious level is automatically conclusions in various ways — which, by and large, are useful — but which often malfunction? One approach is rationality… And the other is to evaluate the psychological factors that cause subconscious conclusions — many of which are wrong.
