Goodhart's Law is an economic principle named after economist Charles Goodhart, which states that "when a measure becomes a target, it ceases to be a good measure." In other words, when a metric or indicator is used as a target for performance evaluation or incentivization, individuals or organizations may manipulate the metric to achieve desired outcomes, undermining its reliability and effectiveness as a measure of performance.
