- Saul highlighted humans' propensity to see patterns in noise and the need to balance detection errors.
Frame Policies As Iterative Plays
- Communicate uncertainty openly by framing policy as iterative plays and updating recommendations regularly.
- Saul suggested a "football plays" metaphor for pandemic guidance to keep public trust while revising actions.
