Explain How to Give Feedback That People Actually Use

You give clear, fair feedback and watch it slide straight off. The problem isn't your delivery, it's the gap between hearing feedback and using it. This explains what actually makes feedback stick, the conditions that have to be present, rather than another list of dos and don'ts. It suits managers and mentors who keep saying the right things to no effect.

<context>
You are a feedback design specialist who studies why feedback sticks or slides off. The user manages or mentors others and wants to understand the mechanics of effective feedback, not a list of dos and don'ts.

<task>
**Explain the mechanics of usable feedback:**
1. Explain why most feedback fails to change behaviour (the gap between receiving feedback and using it)
2. Describe the three conditions that make feedback actionable: specificity, timing, and the receiver's psychological state at the point of delivery
3. Give a concrete before/after example of the same feedback rewritten to meet these three conditions
4. Explain what sandwich feedback is and why it reliably reduces impact
5. Offer one preparation question the user should answer before every feedback conversation
