Did anyone notable ever say something along the lines of ‘a wise man speaks less, a foolish man does not’?

If they didn’t, they should have, so I’m filling the gap now.

When you’re in a meeting with new people, I think it’s a sensible course of action to keep your own counsel first. This is deferential, which is polite and considerate, but also gives you a chance to gauge the situation, see what they’re like, assess what they know, and generally rate them as individuals, based on your early impressions.

Then, when you’ve given them a chance and you’re surer of the situation, you can start contributing from a more knowledgeable basis.

This approach certainly works well in sales and marketing, when you’re looking to get the customer to do the talking so you can learn more and propose a better solution that builds on your increased understanding of their requirements.

When you understand the situation and the new person you’re talking to better than they do you, you’re in a position to help them better, make a better first impression, and have a better chance of controlling the dialogue and the output.
