There is an interesting pattern to clusters of creepy clown reports, which typically feature the following elements: A dramatic initial claim or rumor followed by saturation media coverage. Local residents begin to scrutinize their environment for evidence of this new threat, and begin to redefine ambiguous stimuli within their new stalking clown mind set. This gives rise to new media and social media reports, which in turn generate more publicity and anxiety. The subsequent anxiety and uncertainty are ideal for incubating rumors. A similar pattern is involved in generating sighting clusters of chupacabras, Bigfoot, and the Loch Ness Monster. That is why these subjects belong to the realm of folklore as they break out in waves, are unwittingly driven by journalists and social media—and proof of their existence is never found.
