The original ideas are reconstrued and rapidly spread through an online population gathering support via social media with the core ideas mutating and even diverging, like Chinese whispers.

Psychological biases such as the Baader-Meinhof phenomenon, the illusory truth effect and the continued influence effect are likely to increase and compound adoption of new believers.
