You will be able to handle questions you cannot answer while keeping the audience's trust.
A client asks a question about how your product handles data stored overseas. You are fairly sure of the answer. Not completely sure, but fairly. The room is waiting, your manager is watching, and saying "I don't know" feels like admitting you are not up to the job. So you give an answer that sounds confident. Two weeks later, the client's legal team discovers it was wrong.
Every speaker eventually gets a question they cannot answer. It is not a sign of poor preparation. No amount of preparation covers everything. What matters is how you handle the moment, and the instinct most people have, which is to guess, is usually the worst option.
When you guess and turn out to be right, you gain very little. The audience assumed you knew. When you guess and turn out to be wrong, you lose a great deal. The audience now has a reason to doubt everything else you said, including the parts you were sure of. If the wrong answer led to a decision, the cost goes beyond your credibility.
Saying you do not know, on the other hand, costs less than people fear. Most audiences understand that nobody knows everything. What they want is honesty and a sense that you will get them the answer. A speaker who says "I don't know, but I'll find out" often comes across as more trustworthy than one who seems to have an answer for everything, because the audience now has evidence that you do not bluff.
This matters in Singapore workplaces where saving face can push people towards a confident guess, both for themselves and for their managers. If you took Communicate at work, lesson 8.2, Hierarchy, face and hearing an indirect no, covered how face shapes conversations. In a Q&A, a clean admission handled well saves more face than a guess that unravels later.
A good "I do not know" has three parts: what you do know, what you will find out, and when you will reply.
"I know the system stores data in Singapore by default. I'm not sure what happens when a client asks for a different region. I'll check with our engineering team and email you by Thursday."
The first part shows you are not empty-handed. It gives the audience whatever you can say with confidence, and often that partly answers the question. The second part is honest about the gap. The third part, with a specific time, turns the gap into a commitment.
Avoid vague versions. "I'll get back to you on that" with no date sounds like a polite way of saying never. "That's a good question" followed by a pause sounds like stalling. Be specific about what you will find out and when.
It helps to write your own wording in advance, so it comes out smoothly under pressure. Arjun's version: "I don't have that figure with me. What I can tell you is the overall pattern. I'll send you the clinic-level number by the end of tomorrow."
The admission only builds trust if the follow-up actually happens. Send the answer in writing, by the time you said, to the person who asked. Copy anyone else who would want to know, such as the meeting organiser or your manager if they were in the room.
Keep the follow-up short. Remind them of the question, give the answer, and offer more detail if they want it. "At Thursday's meeting you asked about data storage for clients outside Singapore. Our engineering team confirms that clients can choose to store data in other regions, set up during onboarding. Happy to share the technical details if useful."
A follow-up like this, sent on time, often builds more trust than a quick answer on the day would have. It shows you listened, you took the question seriously, and you do what you say. People remember that.
If you cannot find the answer by the time you promised, write anyway. Say what you have found so far and when you expect the rest. Missing your own deadline in silence undoes the trust the honest answer built.
Sometimes a colleague in the room knows the answer better than you. In that case, invite them to respond. "Farah ran the vendor discussions, so she can answer that better than I can. Farah?"
This is not weakness. It shows you know your team and you care more about the audience getting the right answer than about looking like the expert on everything. It also gives your colleague credit in front of the room.
Two cautions. Only hand over when you are confident the colleague knows the answer and is happy to be put on the spot. A quick word before the talk helps: "If someone asks about the vendor contract, can I pass it to you?" And do not hand over too often. If every hard question goes to someone else, the audience starts wondering why you are the one presenting.
The moment you need these words is a stressful one, which is exactly why you should not rely on improvising them. The activity asks you to write the exact words you will use when you do not know an answer, so they are ready before your next practice session.
Write the exact words you will use when you do not know an answer, and use them in your next practice session.
