Last year my best friend Kelly introduced me into a test called 16personalities.com. At first you might think "another Buzzfeed-like quiz to know which kind of sandwich you are" but this is actually based in psychological theories. It classifies people into 16 personalities according to 4 main criteria, and personally, I feel really identified with my personality type, and also I strongly relate my friends who took the test to their respective personality types. I know human is too complex and it can't be reduced to a single description, but still, it is a good approach to understanding yourself and the people you interact with. Now the important question is: Is anybody here into MBTI 16 personalities? Would be nice getting to discuss about it.
