These tests are easy to break. The MBTI I first took online in 1994. All excited, joined groups, made new friends online, took it seriously, got everybody I knew to take it.
A few years later, I tried to become all personality types and pass as each of them. Took me a few months on and off I’d try. One day, I succeeded. I knew how each 16 thought.
Now I can’t take it anymore ’cause I can empathize with each of the types.
