All models are wrong

Uncommon card · No. 134004

"All models are wrong" is a common aphorism in statistics, and science more generally. It is often expanded as "All models are wrong, but some are useful". The aphorism acknowledges that statistical models always fall short of the complexities of reality but can still be useful nonetheless. The aphorism is generally attributed to George E. P. Box, a British statistician, although the underlying concept predates Box's writings.
