It's a problem everywhere, from bad KPI's to public policy. We have a bias towards metrics that are easy to measure. It's much easier to measure large effects on a single metric, than small effects distributed over a wide range of metrics. Concentrated effects that affect one individual/org/group are favored over distributed effects that affect everyone. There are so many examples of policies where this thought process has been applied.
