Okay so I've found quite a few SPs to be into the same abstract subjects that I am into....Philosophy, psychology, anthropology, and soft sciences. However I have yet to meet an SJ that is into these subjects. Also, the introverted SP's tend to be more into these abstract subjects than the extroverted ones. Hell, just look at these forums. MBTI itself is an abstract subject and there are quite a few ISTP's on this forum as well as ISFP's, but there are hardly any extroverted SP's and the forums are nearly completely absent of SJs. Can anyone explain this?
