During Question-and-Answer sessions, I have seen speakers acknowledge the questioner by saying, “That’s a good question.”

If you must say it at all, only say it once.

The reason is, if you say that after each question, it can sound disingenuous. Or, it sounds like a stalling technique. Or, it becomes an annoying filler.

However, you may genuinely want to add a statement before you answer the question, so you might consider these:

• “That is an interesting perspective.”
• “You are bringing up another good point with that question.”
• “I haven’t considered that before.”

Of course, there is nothing wrong with just answering the question.

My guiding principle is authenticity. If it is a good question, say it. If it is an interesting question, say it. If it is not, just answer the question directly.
