The eight-hour sleep standard that dominates American health advice has surprisingly little to do with sleep science. Instead, it emerged from 19th-century labor organizing and factory scheduling — then somehow transformed into medical gospel.

The iconic image of Benjamin Franklin flying a kite in a thunderstorm is one of America's most enduring historical tales. But Franklin himself never claimed to have done this experiment, and the dramatic story was pieced together long after his actual electrical research.

The image of Pilgrims and Native Americans sitting down together in friendship for a harvest celebration is one of the most familiar stories in American life — and one of the most incomplete.
