In the 1980s, people all around America became convinced that day care centers were secretly practicing demonic ritual sex abuse on children. These allegations stayed in the national news for the better part of a decade. Hapless day care workers were falsely convicted of running sex rings. Evidence of their guilt was manufactured as necessary. In hindsight, this episode looks absurd. How could anyone have believed that there were Satanic day care centers throughout the country? Yet at the time, many reasonable people were swept up in the delusion—as were the prosecutors and elected officials who promised to put a stop to the fake problem. Such is the nature of moral panics. What looks like obvious absurdity from the outside seems totally reasonable to those on the inside.
