Ask what the person already knows before offering your assessment

Ask the person to evaluate their own performance before giving yours.

Why it works

Inviting self-assessment before offering external feedback serves three functions: it checks whether the person has already identified the issue (in which case you don’t need to deliver it), it activates ownership of the problem rather than creating a passively-receiving target, and it reduces defensiveness because the person has already done some of the self-critical work. When self-assessment and external feedback align, the feedback is received as confirmation rather than attack.

How to do it

1. Open with: "Before I share my observation, how do you think that went?"
2. Listen fully before adding anything — the self-assessment is data.
3. If they identify the issue themselves, your job is to agree and deepen, not to deliver the critique freshly.
4. If they miss the issue, introduce it as an addition: "I noticed one thing you didn’t mention…"

Evidence

Self-assessment before feedback is the "ask" in the ask–offer–ask (elicit–provide–elicit) structure from motivational interviewing and coaching. It draws on self-perception theory: conclusions people reach themselves are more durable than those given to them. (clinical)

Well-established in clinical coaching contexts; formal experimental studies on self-assessment before feedback in organizational settings are limited.

Common mistake

Asking for self-assessment while visibly waiting to deliver the "real" feedback — if the self-assessment question is read as a preamble, the person performs expected humility rather than genuinely reflecting.
