The conspiratorial worldview, as opposed to the accidental, is in the minority. Therefore to hold such a view necessarily threatens to undermine a person’s emotional need for peer acceptance.
When a critical human need is challenged and potentially undermined by facts, cognitive dissonance takes over the emotional mind and facts become immaterial. The person will flail about in a defensive emotional panic. “Conspiracy theorist!”, they’ll scream – without even knowing what the words mean.
Need for the familiar comfort and reassurance of peers sends them running backward to join the herd. The cowardly but confident mob regurgitates conditioned platitudes and happily sings its learned slogans.
“Four legs good, two legs bad!“, they bleat, having been overtaken by an immediate emotional need which is so strong that they willingly embrace their own slow death.
