THE IDEA

A closer look.

A measure can lose its connection to the goal it once tracked when people begin optimizing it. Incentives, gaming, and changes in behavior can all weaken the relationship.

Why it matters

A target should be evaluated alongside the underlying purpose it is meant to serve.

WHERE IT BREAKS

A useful lens. Not a universal law.

  • Targets do not always fail. The effect depends on the design of the measure, the incentives, and how easily behavior can adapt.
