The bottom line:
People who doodle when they are exposed to verbal information retain more of that information than their non-doodling counterparts. We think doodling is something you do when you lose focus, but in reality, it is a preemptive measure to stop you from losing focus….
Under no circumstances should doodling be eradicated from a classroom, or a boardroom, or even the war room. On the contrary, doodling should be leveraged in precisely those situations where information density is very high, and the need for processing that information is very high.
