Typing other people can be a challenge, especially if you do not know them personally. If you cannot ask someone about their personality, the best you can do is collect clues and make an educated guess. Here is a brief look highlighting some of the characteristics to help you spot or recognize a person’s Myers-Briggs personality type.
You can spot an INFJ by their edgy and sometimes brooding demeanor that is interspersed with flashes of light-heartedness and enthusiasm. They are the ones who often act as the moral voice in their group. They seem very insightful and wise and often seek to point out the nice things they observe in other people and make them feel good about themselves. INFJs can often be found in the arts especially that of drama and theater. They are likely to be a bit of a klutz and accident-prone thanks to their inferior Se. INFJs are often polite and careful not to offend other people although they themselves may get their feelings hurt more frequently than they care to count.
