Facilitator Notes & Model Answers — Lesson 13

For instructors and self-study · Model walk-through and rationale

Model decision walk-through

StepModel reasoning
Evidence vs inferenceKnown: an alert fired; two analysts disagree. Inferred: it is/ isn't real; the sector campaign applies. Keep the two apart
Base rateAcknowledge many such alerts are false, but the cost of a missed real one is high — asymmetric
First moveA reversible protective step (e.g., increase monitoring, restrict the suspect access) while verifying in parallel
One-way doorsDefer public statements and attribution until certainty improves

Bias checklist (model)

Why the poll answer is C (reversible action + verify in parallel)

Teaching point: the two failure modes are paralysis and panic. Discipline lives in the reversible action taken while investigating.

Homework — what good looks like

Task 1

Strong checklists specify a no-regret first action and a self-known bias, not generic "stay calm."

Task 2

The best thresholds are testable in the moment ("two independent confirmations of X"), decided while calm.

Task 3

Good answers pair an honestly identified bias with a concrete ritual to counter it next time.
