If the facts are known, say, accessible to all, then placing a whole bunch of really smart people in the same room is unlikely to yield greatness. Such a situation is liable to result in a room that is tempered and inhibited, i.e., a field-leveler. Even if the room temperature rises and beers are passed, there'll generally and quickly be little oxygen left in the room, such that if greatness exists, it too will suffer from hypoxia and suffocate; those whose faces go red suffer from hypercapnia (high CO2), which combined with hypoxia (asphyxia) leads to a disorientated state, delusions of grandeur and narcosis :-) But, in a room that remains obscure, with lots of diversity, and unknowns, the real-deal can readily be recognized because they light-up the room where previously there was only darkness.<p>The difference between greatness and IQ seems to be one of unfettered, uninhibited, irreverent, and penetration insight into the unknown and seeing the invisible fabric of the world, the rest is simply box-ticking.<p>PS: I'm not great, I can just see greatness
