PositiveThe Guardian (UK)I finished Quiet a month ago and I can\'t get it out of my head. It is in many ways an important book—so persuasive and timely and heartfelt it should inevitably effect change in schools and offices ... her suggestions on how to redress the balance and make the world a bit more introvert-friendly are charmingly cautious ... But sometimes her brilliant ideas aren\'t written quite so brilliantly. Her book can be a bit of a slog, not always a page turner. I wish she\'d spent a bit more time adventuring and a bit less time analysing and philosophising and citing vast armies of psychologists ... Her thesis—built on the assumption that almost everyone in the world can be squeezed into one of two boxes— may topple if it turns out that loads of us are essentially ambiverts. I suspect there are a lot of ambiverts out there.
