Sunni Brown's argument:
Doodling, at least in the US, is perceived as inappropriate in virtually every learning environment in which we find ourselves – in the classroom, boardroom and Situation Room. But this persistent cultural view works against us. As a cognitive tool, the doodle is incredibly useful. … Visual language – something as sophisticated as a wireframe or as simple as a doodle – is native to our brains. To suggest implicitly or openly that learners should rely solely on text or auditory content to understand complexities and solve problems is to deny the brain one of its most fundamental and profound ways of understanding.
