"Understanding other people" -without interacting with them.
Understanding and maximising your strengths
Understanding and overcoming your weaknesses
Determining potentially fulfilling careers/interests
Understanding and improving social interactions
To feel unique
To feel "normal" - meet likeminded people
Understanding other people
Proving and confirming your own superiority
As fodder for endless poetic sounding forum rants
To brainwash the masses with your corporate agenda
A self esteem boost
As a shorthand language to discuss/explore deeper concepts
Use? I'm an Intuitive...
To wipe your backside
