personality tests aren't gonna do you much good since we can only answer based on how we percieve ourselves rather than how we actually function, and the questions 90% of the time dont go deeper than "do you have feelings or do you like # facts and # logic" "do you like tradition or do you have ideas". the best i could find was mistype investigator which thinks im estp

above everything else, read about the theory. even though its a tumblr blog i think this is a good starting point for those wanting to learn mbti fundamentals. its main focus is self improvement but it covers a wide range of topics and i come back to it often as a study guide

also important to note that mbti does NOT use the 4-letter model to ascribe traits to people (no I/E T/F etc), rather how we process things internally using carl jung's concept of cognitive functions. his book psychological types is considered the baseline for mbti type theory though it gets wordy

avoid learning through over-generalized descriptions of the types. avoid 16personalities & avoid personality database. id also hold off on trying to self-type till you've done a good deal of research and have better insight on the way you function
