# Metricmirror

Review how a success metric changes behaviour and what valuable work it fails to count

Layer: Mind · Category: Strategy

## Mechanism

When a [Metric](https://mindscape.world/scapes/bootstrap/Metric.md) is used to judge work, it is reviewed on a stated schedule for two things: behaviour that has shifted to raise the measure without serving the goal, and valuable activity the measure does not count. Findings are recorded with the metric.

## Invariants

- The metric is reviewed on a stated schedule.
- Each review records observed gaming and valuable activity the metric misses.

## Failure modes

- Goodhart drift: work optimises the measure, not the goal.
- Mirror blindness: reviews look only at the measure and so find nothing.
