They may appear to drift about in an unending daydream, but Logicians’ thought process is unceasing, and their minds buzz with ideas from the moment they wake up. This constant thinking can have the effect of making them look pensive and detached, as they are often conducting full-fledged debates in their own heads, but really Logicians are quite relaxed and friendly when they are with people they know, or who share their interests. However, this can be replaced by overwhelming shyness when Logician personalities are among unfamiliar faces, and friendly banter can quickly become combative if they believe their logical conclusions or theories are being criticized.
Also, this paragraph on friendships certainly rings a bell :)
Many of the usual motivations for making friends – emotional support, social validation, shared routine – simply don’t apply to Logicians. More likely, these concepts are met with disdain, as people with the Logician personality type prize intellectual depth above all else. It is not easy to become good friends with Logicians, but if there is a common interest and a common train of thought, the connection is likely to spark instantly, surprising everyone else who thought they had this distant personality type pegged.
I also realized why it is that Smarty and I get along so well - I am exactly same type (INTP) except I really "straggle the boundary" between perceptive and judgmental traits (51% P and 49% J). I share the same strengths and weaknesses, and therefore I can both sympathize with her and also appreciate her strengths. I hope that just like I did, Smarty will find her tribe and, eventually, a partner who will appreciate both her initial coolness and the fire of her convictions.
Do you know your personality type?
