Why the Best Trainers Say “I Don’t Know.” And How to Use It

Question

How do you handle not knowing an answer during training?

Direct answer

Be direct: “I don’t know” is better than hedging. Add what you do know, commit to following up, and invite collaboration. You can also redirect to the group (“Has anyone encountered this?”) or share your investigation process live. Honest uncertainty builds trust and models professional judgment.

Evidence

  • Prevalence: 70%+ of people report experiencing imposter syndrome at work.
  • Trust effect: admitting uncertainty increases credibility by clarifying boundaries of knowledge.
  • Best practice: state uncertainty, add context, and commit to a concrete follow-up.

Follow-up questions

Does imposter syndrome affect subject matter experts?
Yes. Over 70% of people report experiencing imposter syndrome at work. For experts asked to teach, it can feel worse because their job suddenly includes a skill they were never trained for. The key insight is that expertise is not knowing every fact; it is deep familiarity with how a domain works and where uncertainty begins.
Why does saying “I don’t know” build trust in training?
When you admit uncertainty sometimes, learners trust your certainty more. It models good professional behavior, invites collaboration, and reduces the pressure to perform perfect expertise. Real experts know the boundaries of their knowledge and can explain how they would find answers responsibly.

The expertise trap

We assume experts know everything about their domain. This creates impossible expectations for anyone asked to train others. The reality is that expertise is always partial. New situations arise, old knowledge becomes outdated, the domain evolves faster than anyone can track.

When trainers feel compelled to have all the answers, they bullshit (learners leave with wrong information), deflect (learners stop asking questions), overcomplicate (hiding uncertainty behind jargon), or burn out from the constant vigilance of expertise theater.

The “I don't know” advantage

It builds trust. When you admit uncertainty, learners trust your certainty more. If you say “I'm not sure about X” sometimes, they believe you when you say “I'm confident about Y.”

It models good behavior. In most domains, pretending to know when you don't is dangerous. Trainers who admit uncertainty teach learners that it's professional to do the same.

It invites collaboration. “I don't know, but let's figure it out” turns embarrassment into shared learning. These moments often produce deeper understanding than prepared content.

It reduces pressure. Once you've said it and survived, the fear diminishes. You can relax and focus on actually helping learners.

How to say it effectively

Be direct. “I don't know” beats hedging. Vague non-answers damage credibility more than honest uncertainty.

Add what you do know. “I don't know the exact number, but I know it's in the hundreds” shares adjacent knowledge that frames the gap.

Commit to following up. “I'll find out and email everyone” demonstrates accountability. Then actually do it.

Share your process. “I'm not sure, but here's how I'd figure it out...” teaches meta-skills that are more valuable than any single fact.

Stop thinking of yourself as teaching facts and start thinking of yourself as teaching judgment. Facts can be looked up. Judgment comes from experience. And judgment is what learners actually need most.
