Anomaly Puzzles: How the Brain Detects the Unexpected
Psychology Today | 30.06.2026 00:02
Simply put, an anomaly is something that deviates from what is expected. The human brain is highly attuned to detecting patterns, becoming especially alert when those patterns are violated. This ability is often highlighted in mystery and detective stories. In Arthur Conan Doyle’s 1892 short story, The Adventure of Silver Blaze, Sherlock Holmes concludes that the horse thief must have been familiar to the stable because the guard dog did not bark during the crime. Holmes deduces that the thief must have been someone the dog knew, and thus that it was an inside job, which turned out to be true.
