What this resource explains
Soren Tsui argues that public-safety policy should be judged by measured outcomes rather than stated intentions. Research may reveal that a policy failed or produced inequitable harm, but the system often lacks a routine mechanism for acting on that finding.
Measurement matters only when someone has the authority and obligation to respond.

See how this idea helps with a decision
Here is an example to work through. The linked source explains the idea or guest account. The next move is ICM guidance.
- Where it shows up
- A policy was announced as a reform, but no one is responsible for checking the effect on people it reaches.
- A useful move
- Name the expected result, the data and lived feedback, an unintended-effect measure, and the official able to revise the policy on a set date.
- What this does not prove
- A favorable statement of purpose cannot establish benefit; a single outcome trend cannot establish causation.
