It is basically a version of the Big 5 personality test if you look the little color pinwheel at the end.

Psychologists actually do use this. They test based on openness, conscientiousness, extraversion, agreeableness, and neuroticism

This test is basically describing the same thing but in less black and white terms. It might be really interesting to see what a T makes of it and if it matches up..
