This is a technique I’ve used for a long time. While I may not wait 10 seconds, I always wait at least 2 or 3 when I’m having questions thrown at me - usually by an unreasonable manager. I have found a lot of managers in the IT industry love to angrily barrage you with questions in the hope that you make a mistake and answer the way they want you to - usually in order to take responsibility for something that is actually their fault.
And the best thing is if they also use the same technique, with both of you doing it, it make the whole conversation go off the rails. One of parties has to stop with the wait to answer technique in order for the conversation to get back on trrack, all you to do is make sure that it isn’t you.
