 "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 observer.* 
 They called this *the Delphi effect [https://en.wikipedia.org/wiki/The_Wisdom_of_Crowds[Wikipedia^]][https://en.wikipedia.org/wiki/Collective_intelligence[Wikipedia^]].* +
