Science & TechMental model

Extraordinary claims require extraordinary evidence.

Carl Sagan made the line famous in 1980 in his series 'Cosmos', discussing alleged alien visits. The idea is older: Laplace wrote in 1814 that the weight of evidence must match the strangeness of the claim; Hume said similar in 1748. The core: the less likely something is beforehand, the stronger the evidence needed to make it credible.

Useful: A shaky video is proof enough for a dog in the park, not for a UFO.
