Carried over from here to start a new thread.
EDIT: Realizing a lot of people may not want to start of a thread by clicking on a link, I'll summarize.
Recent research in psychology has found that thought and emotion are not disparate processes but are instead interdependent. Emotion is particularly important in decision-making processes. One important book in the field is Descartes' Error.
And I'll add here that I think that understanding these advances is important in having a more accurate idea of the psychology of both "thinkers" and "feelers". It can help to avoid "stereotyping" as opposed to "typing".
I'll also add that I realize that feeling and Feeling are not the same in MBTI, but nonetheless many times I see both thinkers and feelers - but most often thinkers - conflating feeling with Feeling. I also see thinkers making the assumption that their own thought processes are relatively free of emotion. Whereas if Descartes' Error and other like research is correct, it is not only impossible but undesirable for human thought to be free of emotion.
