How a made-up bathtub history sounded believable
In 1917, American humorist H. L. Mencken published a mock history claiming that bathtubs had once faced official restrictions because people considered bathing dangerous. The story’s trick was to dress absurdity in the clothes of a researched account: it supplied dates, civic authorities, and medical objections, details that made the invented history feel checkable and familiar.
That approach landed in a culture where bathing practices and public-health advice really were changing. Readers knew that doctors and officials debated cleanliness and disease, so a tale about authorities worrying over a new bathing habit did not sound impossible at first glance. Mencken’s straight-faced presentation also gave readers little warning that the supposed history was satire.
The hoax outlived its punchline
Mencken later acknowledged that he had fabricated the account. But the story’s specific, confident details proved easier to remember than its satirical purpose. It became a durable example of how a plausible explanation can travel as fact when readers encounter it without the original context.
The bathtub was not the real source of the story’s power. It was the way Mencken made an invented past resemble the kind of official history people expected to trust.
