Goodhart's law

Economic adage stating that when a measure becomes a target, it ceases to be a good measure. This principle highlights the problem that once a metric is used as a target for decision-making, individuals may alter their behavior to achieve the target, often resulting in unintended and counterproductive outcomes. Goodhart's Law is particularly relevant to policymakers, economists, and business managers who rely on metrics for performance evaluation and strategic planning.
