INTP's are relatively easy-going n amenable 2 almost anything til their principles are violated, about which they may become outspoken n inflexible. They prefer to return, however, to a reserved albeit benign ambiance, not wishing to make spectacle

Tip offs that a person is an INTP: their obsession with logical correctness. Errors are not often due to poor logic - apparent faux pas in reasoning are usually a result of overlooking details or of incorrect context.
