> The map isn't dangerous in and of itself, but it becomes dangerous when the mapmaker gives the impression that it gives more detail than it actually does.

I agree. I've seen this misused quite a lot.

Psychometric testing is interesting, and can reveal tendencies - but that's about it. Certainly using this as "hard data" for things like hiring, corporate restructures, etc, is fraught with issues.

In reality, the best predictor of a person's behaviour is (a lot of) detail on past performance. Even then, there are flaws.
