What to say when you do not know the answer

Someone asks you a direct question in front of other people. A decision, a number, what is happening with the reorganisation, whether their project is still going ahead.

You do not know. And there is a half-second where you decide what to do about that, and in that half-second a surprising number of new managers choose to produce something that sounds like an answer.

Not a lie exactly. A confident-sounding assembly of things that might be true. It gets you through the meeting, and it costs you more than the silence would have.

Two reasons, and the second is the expensive one.

The first: you will be found out, usually quickly, because somebody in the room already knew the answer. People rarely ask a question they have no information about.

The second, and this is the one that matters: your team is trying to work out how much of what you say they can rely on. Every confident answer you give is going into that calculation. If some of your confident answers turn out to be guesses, then all of them become guesses, including the ones that were true.

Once that happens you have lost the ability to be believed when it counts, and getting it back takes a very long time.

Because you have confused two different things: knowing the answer, and being worth listening to.

In your old job, those were close to the same thing. You were promoted largely because you knew things. So "I do not know" feels like admitting the promotion was a mistake.

It is not the same thing in this job. Nobody expects you to know everything about work you are no longer doing, plus decisions made two levels above you. What they expect is that you will find out and come back, which is a thing you can actually deliver.

The basic version, which is three sentences and almost always enough:

"I do not know. I will find out and come back to you by Thursday."

Then come back by Thursday. Even if the answer is still unknown — especially then. "I still do not have an answer, I have asked again, I will chase on Monday" is worth more than silence, because it proves the first promise was real.

When you cannot say, rather than do not know:

"I do know, and I am not able to share it yet. As soon as I can, you will hear it from me." People handle this far better than managers expect. What they cannot handle is sensing that something is being hidden and being told nothing is.

When you half know:

"Here is what I am fairly sure about, and here is the bit I am guessing at." Separating those two out loud is one of the most trust-building habits you can build, and almost nobody does it.

When it is a decision you have not made yet:

"I have not decided. I will by Friday, and I will tell you what I decide and why."

Say the uncertain part out loud, every time, even when nobody would notice if you did not.

"I think the deadline is the 14th — let me check." "I am fairly confident that is right, do not act on it until I confirm." Small, unglamorous, and over a few months it turns into something genuinely valuable: when you say you are sure, people believe you, because they have watched you say when you were not.

That is what confidence looks like in a manager. Not having every answer. Being reliable about which ones you have.

Do not use "I do not know" as a way out of a question you simply do not want to answer. People can tell the difference, and it burns the phrase for the times you need it honestly.

If you do not want to answer, say that instead: "I would rather not get into that one." Less comfortable, more honest, and it leaves your "I do not know" meaning exactly what it says.
