Cancer here. I recently had a typing session with my older cousin (also cancer), and he was so INTP it was crazy. The spider hands, subjective thought, the Ne flashes in his eyes, the propensity for Si, and can't forget the raw, untamed Fe. I've known him for 20+ years - it was an easy typing to do.
Funny because I sort of eased them (him and his fancy) into MBTI bit by bit, starting with her type (which she already knew from before), so by time I got to his the skepticism had worn off a little ... anyways they were pretty sure he was extraverted because when he is at work (electrical engineer) he becomes a little lonely when he isn't given the chance to cooperate with other people towards a common goal, plus he gains momentum (appears to) as he socializes with more and more people at a party. When asked to decide if he was a thinker or a doer, they both laughed and said well THAT is an easy answer.
There are (I think) 4 more cancers in my family (INTJ, ISTP, ESTJ, ESFP) all blood relatives to each other, to me, and to my cousin.
Whoops not trying to derail this thread.
Astrology? He also made the same connection (probably subtly alluding to the fact that our birthdays are 2 days (plus a whole number of years) apart). We never actually discussed it. Then they called me a fortune teller HAHA.
I think your birth sign has less to do with your personality type than it does with the time of year you were conceived. However, I have a
bad track record with Libras and I've found them to be incredibly emotional.
I remember reading somewhere that INTPs are supposed to "like esoteric things" so it's okay to admit you're into astrology
