Mondo Knows Facts
Popper argued science must be falsifiable
A claim counts as scientific only if some observation could prove it wrong Karl Popper argued in the 1930s that no amount of confirmation settles a theory, while a single clear contradiction can. The principle separates testable claims from ones that can accommodate any result. Working scientists apply it loosely, but it remains a standard for what counts as evidence. It sits in Mondo's science collection, one of 200 facts that each trace back to the reference below.
