I quite agree with you. We should generally spend more time working without seeming to work, which is part of the problem. I get a lot of work done staring out the window, taking showers, etc. I don't recall any particularly great ideas while on the can... I think the appearance of doing work is now very important. So sitting and thinking has the problem that you might be thinking about the problem or who knows what? Possibly there's a causation problem here - if you are already a famous scientist, you can probably be trusted to "sit and think".
