The wisdom of crowds is a well known principle, used in engineering to overcome something that is extremely difficult to measure (noisy data for instance), considering only one single measurement would be very dangerous, since it might be extremely imprecise. However, if you measure 1000 times and take the average, the errors cancel out and you have a pretty accurate measurement :) [VIDEO]
Human social psychology, aka. "The wisdom of crowds, and the stupidity of herds" (1), in which the average opinion of large groups of people is closer to the truth, than each individual opinion. By informing all individuals of the propaganda you wish to spread, you can influence that average, hijack, and change it to the stupidity of the herd aka. Gleichschaltung (2), which is why these people want to decide what is and what isn't "dangerous" speech. Fuck'em. 1. [LINK] A shorter explanation: [VIDEO] 2.
