Actually, I do.
I really like the mechanism provided by the Myers-Briggs Type Indicator (MBTI). It’s made up of four designators, with two possibilities for each, for a total of 16 different personality types possible. To us MBTI, you only need to answer four questions about someone to estimate their “type”. It’s easy enough to use and once you have a good idea of type, a lot about tendencies to expect for a person can be known. Of course, that is just to estimate what someone else may be, the actual self-test is A LOT more questions.
I am an MBTI “ENTJ”.
I am not as big a fan of the Enneagram, but many people like it as much or more than MBTI and use it to compliment MBTI.
I am an Enneagram “8w7”.
Finally, in a work environment, it would be so much easier if everyone just walked around with a FIRO-B sign indicating their type. I LOVE this instrument and if I have to recommend just one to a business, this is it.
Here’s my FIRO-B:
