CONCEPT

loi de Goodhart

Goodhart's law — when a measure becomes a target, it ceases to be a good measure, because optimizing the metric distorts the behavior it was meant to track. It is a caution for AI development: benchmarks and productivity metrics can be gamed once teams steer directly at them.

Origin

Attributed to economist Charles Goodhart (1975); its common phrasing — a measure that becomes a target ceases to be good — is due to Marilyn Strathern.
