Definition stolen from The Cathedral and the Bazaar:

Sociologists years ago discovered that the averaged opinion of a mass of equally expert (or equally ignorant) observers is quite a bit more reliable a predictor than the opinion of a single randomly-chosen one of the observers.

This is exactly why I rather brainstorm with an AI than a colleague: it’s as if I were talking to ten thousands experts with infinite winsdom and experience vs. talking to a single busy person.
