You Don't Know the Answer in a Meeting

The moment

The room goes quiet and every head turns to you. “What's the number on that?” You don't have it.

I've watched smart, prepared people lose a room in that moment. Not because they didn't know. Because they didn't have the words for not knowing. The gap isn't the problem. The next five seconds are. Let's fix that today.

The short answer

• Say: “Here's what I know, here's what I'd need to confirm, and I'll have it to you by [time].” That one sentence does the whole job.
• Never guess out loud. Research shows a confident answer that turns out wrong costs you more credibility than an honest “I'll confirm.”
• Answer the part you do know first. Partial knowledge, stated clearly, reads as competence.
• Name a time and keep it. Keeping the promise is where credibility is actually won. Beating it buys you nothing extra.

What to say: the breakdown

The short answer above is the whole thing in one sentence. Here it is in the five pieces you'll actually use, in order: four in the room, one right after.

Quick note. I don't hand people lines to memorize, because nobody sounds like themselves reciting. What I give you is the structure and the reason behind it. The examples show you the shape. You bring the words. That's what makes it land.

1. In the room: give what you know first

Say this: “Here's what I can tell you right now: [the part you know].”

Not that: “Um, I'm not sure, I'd have to check.”

Why it works: the first words out of your mouth set how the room reads you. Leading with the piece you do know keeps you in the position of the person who has information. And it stops you from filling the silence with a guess, which is the real risk. In a study published in Psychological Science, people rated a confident witness as more credible, until that witness was caught in an error. Once the confident person was caught being wrong, their credibility dropped more sharply than the hedger's, and in some cases the person who had hedged came out ahead (Tenney, MacCoun, Spellman and Hastie, 2007). Read the study summary.

Action step: before any meeting, write down the three things you know cold about your topic. One of them is always usable.

2. In the room: don't guess. Say why.

Say this: “That's a number I don't want to guess on. I'd rather get it exactly right.”

Not that: “I think it's around… maybe… 40 percent?”

Why it works: “I don't want to guess” is a judgment, not a gap. You've reframed not knowing as a standard you hold. And people don't punish honest uncertainty the way we fear they will. Across a series of experiments, advice given with clear uncertainty (a range, a “more likely”) was not disliked, and when people had to choose, they often preferred the adviser who admitted uncertainty over the one projecting false certainty. A vague “I'm not sure” didn't fare as well, which is why the words around it matter (Gaertig and Simmons, Psychological Science, 2018). Read the study.

Action step: practice the line out loud, slowly. The pace is the message.

3. In the room: put a time on it

Say this: “I'll have that to you by end of day.”

Not that: “I'll get back to you.”

Why it works: “I'll get back to you” is what people say when they won't. A specific time closes the loop in the listener's mind so the meeting can move on. It also sets up the moment that matters most: keeping it.

Action step: pick a time you can keep, then keep it.

4. In the room: when the question is really a challenge

Say this: “Good question. Tell me more about what's behind it, so I bring you back the right thing.”

Not that: getting defensive or over-explaining.

Why it works: a sharp question usually has a concern underneath it. Asking for it turns the questioner into a collaborator and buys you the time you needed anyway.

Action step: count to two before you answer any sharp question. The pause reads as thought, not fear.

5. Right after: the follow-up that earns it back

Do this, within the hour if you can:

Hi [name], following up on your question in today's meeting about [topic]. The answer is [answer]. One line of context: [context]. Happy to walk through it if useful. — [you]

Not that: a long email explaining why you didn't have it.

Why it works: this is the moment people decide whether “I'll confirm” was a dodge or a promise. Researchers at Chicago Booth and UC San Diego found that breaking a promise clearly hurt how people felt about the person who made it, but going above and beyond the promise earned no more goodwill than simply keeping it (Gneezy and Epley, Social Psychological and Personality Science, 2014). So don't over-deliver. Deliver, on time, in three lines. Read the study summary.

Action step: block ten minutes right after the meeting, before anything else.

The whole conversation

Them: “What's the churn number on that segment?”

You: “Here's what I can tell you now: overall churn is down this quarter. The segment-level number I don't want to guess on. I'll have it to you by end of day.”

Them: “Fine.”

You, at 4:10 pm: “Following up on the segment churn: 6.2 percent, down from 7.1. Detail attached.”

That's it. Two sentences in the room, one email after. Nobody remembers that you didn't have it. They remember that you did by four.

Questions people ask

Is it bad to say “I don't know” in a meeting?

Saying only “I don't know” is weak. Saying what you do know, what you'd need to confirm, and when you'll have it is strong. The words around it decide how it lands.

What if my boss expects me to have the answer?

Then the follow-up matters more than the moment. Get the answer fast, send it short, and the next time you say “I'll confirm by end of day,” they'll believe you.

Should I ever just guess?

Only if you label it: “My rough sense is X, but I'd want to confirm before anyone acts on it.” Research suggests a confident claim that turns out wrong costs you more credibility than one you flagged as uncertain.

What if I freeze and can't find any words?

Buy three seconds: “Let me think about that for a second.” Then give what you know first. Writing that opening at the top of your notes before the meeting makes it come back faster.

How do I stop this happening so often?

Ask your manager once: “Which two or three numbers should I always have ready for these meetings?” Most hard questions repeat, and you've shown you care about the room.

Next meeting, try the first move. Just that one. Then come tell me how it went on Instagram.
