I've don't many of those tests, psychometric and profiling and it's interesting how accurate they can be, although I've seen some that have been a little skewed. It's interesting how people take them though, on a personal level, how it can change their behaviours initially until they lapse back into who they really are because it's pretty difficult to fake it for long.

I actually think there's merit in knowing, in understanding oneself in that way and on deeper levels.
