Friend of the Revolution, Wendy, wrote in to point out this article, which says that people who doodle during meetings have a higher focus and higher information recall than people who don't doodle.
I did a little digging and pulled out the actual paper on doodling submitted for applied cognitive psychology.
The upshot of this is that during a meeting if you look around and see some people doodling and others not doodling you should stop the meeting and say, "HEY. I NEED YOU PEOPLE TO PAY ATTENTION. START DOODLING!"
