there is this stereotype that F = emotion and that any F type is controlled by emotion and therefore incapable of thinking rationally. it is a complete misconception about the nature of feeling and thinking. in reality, emotion is a human trait (not confined to F types) and the term "feeling," as used in MBTI theory, is more related to values than it is to emotion. any type can think logically; that is not confined to T types. T and F vary in what they prioritize when they evaluate or decide...not in capacity for logic. and we F types can be very logical and very emotional simultaneously. i'm highly emotional by nature, but, as an INFJ engineer, after all....i have to be logical. lol
also, some INFJ descriptions are so idealized that we are made out to be some sort of angels. this is troubling because it is so false. INFJs are no different from anyone else - we are just ordinary people - and no people are perfect. we really do care about other people's feelings and make decisions to protect others due to Fe, this can lead to self-sacrifice on behalf of others, and compassion comes naturally, but this doesn't make us angels. i can't speak for everyone else, but as an INFJ i make just as many mistakes as anyone else...and, sure, there are some INFJs who are heroically unselfish, compassionate, and loving; but there are some people of every personality type who could be described that way; that does not define a personality type, but rather a set of life choices. what comes naturally (by default brain settings) does not dictate what people become - what people become is a result of the choices they make, and people can go against their natural instincts. the misconceptions need to be set aside...there is no reason for the INFJ type to be put up on a pedestal.
