Useful Personality Tests

Have you ever taken a per­son­al­ity quiz/​test that helped you have valuable in­sights? If so, what were the tests and how were they use­ful?

The only use­ful ones I’ve found all yielded the same type of in­sight. They showed me where I stand rel­a­tive to oth­ers, which is can be gen­uinely use­ful since rep­re­sen­ta­tive sam­ples of large pop­u­la­tions can be hard to come by. This in­cludes IQ tests and tests for men­tal di­s­or­ders (in my ex­pe­rience, peo­ple are usu­ally aware that they are, for ex­am­ple, smarter than the av­er­age (al­though the Dun­ning-Kruger effect might com­pli­cate this) or have some in­tru­sive thoughts and com­pul­sive rit­u­als, but might be sur­prised to find that they are three stan­dard de­vi­a­tions above the norm or that their symp­toms are suffi­ciently se­vere to be con­sid­ered OCD).

No re­motely re­li­able (as in, not as­trol­ogy) test I have ever seen has re­vealed gen­uinely sur­pris­ing in­for­ma­tion for a mod­er­ately self-aware per­son, out­side of rank­ing. Fur­ther­more, they rarely gather per­son­al­ity data in a re­motely sub­tle or non-trans­par­ent way (“do you like spend­ing lots of time with large groups of peo­ple?” “yes...” “sur­prise, you’re an ex­tro­vert!”), and thus seem su­per sus­cep­ti­ble to test-tak­ers’ at­tempts to con­firm a de­sired iden­tity.

An ex­am­ple of a more in­ter­est­ing/​sub­tle way to po­ten­tially con­duct a per­son­al­ity test would be to use ques­tion like OKTrends’ “do you like beer?” which clusters strongly with “do you have sex on the first date,” and, po­ten­tially, sex­ual open­ness. Such re­sults might be harder for ma­nipu­late (con­sciously or un­con­sciously) and could as­sist with deeper self-aware­ness.
