ABSTRACT
Core Question There are two general opinions of crowd knowledge. One, that the crowd is easily influenced by hysteria, mania, or madness and often mimics or follows without proper consideration, largely because the crowd is made up of uneducated, non-experts who lack the proper training to determine the best course of actions. Galton and MacKay emphasize this view.1 The other is the opposite: that the crowd follows the “two heads are better than one” mantra and that the aggregation of information is superior to the knowledge of any one individual, regardless of one’s level of expertise.2
