Folk psychology knows and uses the concept of "being of the same mind" that often is supposed to explain why two people find themselves sympathic or like (or even love) each other.
"Being of the same mind" includes
- beliefs and models
- preferences, values, and interests
- liking and disliking (of other things and persons)
It depends on the proper individual mix of similarities of minds that lets one find someone else sympathic, and sometimes it's the same mix that lets two people like each other. Note, that the proper mix may either be an enabling factor (a necessary condition), or a driver (a sufficient condition).
I wonder if there is a single scientific term for "being of the same (or similar) mind", and which role it plays in scientific psychology. (Maybe none because it's considered too unspecific a concept - or even undefinable.)
