Reposting to say that for me, the test you linked is inaccurate. I took a different one today that used the same Myer-Briggs scale, and it gave me what was actually a valid analysis of my personality and it didn't throw two 1% (one in the wrong direction) results at me because unlike the linked test, the one I took today actually worked.
So I'm actually ISTJ
