Recently, I took the Enneagram test. I'm either a type 8, type 4, or type 6. Also either a 8w7 or 8w9. This doesn't surprise me much since it fits my experience with every other personality test. I don't neatly fit into one category and the way I act and think dramatically shifts depending on the circumstances. Frankly, I think Meyer-Briggs is obsolete bullshit unsubstantiated by modern reseach. People who take it too seriously come off as pretentious and simple-minded to me and on forums it's like they actively try to fit the stereotype. I think it appeals to people who don't have anything real going for them. The missing piece is taking into account how people's personalities naturally shift. The brain is remarkably complex, but what we perceive as personality is basically an illusion.
Anyway, I thought about how you could make a better test and came up with some ideas. Aside from testing for general behavioral tendencies like extraversion and introversion, I think there should be sub-catergories depending on other factors:
How you interact with people you see as socially and emotionally above, equal and below you. By socially above, I mean like societal position. A boss or parent or teacher is above you. Emotionally above is somebody you actually respect and look up to. A boss you think is an asshole or idiot is somebody you see as socially above you, but emotionally below you, etc.
How you deal with your own and others social/emotional challenges.
How you deal with your own and others social/emotional desires.
All of the questions will also take into account whether you feel content or discontent(sadness/anger) socially/emotionally. Depending on everything, your results would also include stable/unstable and successful/unsuccessful.
Overly positive descriptions give people a warped sense of self-perception. Taking into account whether a person is well adjusted or not would give more accurate results. I think this whole thing could only be accomplished by asking about complex scenarios and including some more personal questions.
