Former lawyer Susan Cain spent 7 years researching and writing her book, Quiet. The Power of Introverts in a World That Can't Stop Talking - you can find a clip of her talking about the process of writing and the key messages here. It's amazing that these simple concepts about how different people learn best and do their best work, are so readily overlooked by organisations and educational institutions.
While this is undoubtedly and important book, what struck me most having read it was the age old argument about whether labels of this type are helpful to us at all. What shines through the argument for being more accepting of introverts, is perhaps the need for all of us to see everyone as their own 'type'. Take the time to understand individuals strengths and weakness, how they love to learn and what excites them, and the need to label is surely removed and cannot get in the way learning and performance?
