Because it’s widely held to be, head and shoulders, perhaps the single most important existential question.

I’m in many ways a behaviourist. When I read about a super intelligent person such as Chris I want to know so what has s/he done with the talents they have or as woo woos would say were ‘given’.

IMHO that’s what counts.
