Quiet: the Power of Introverts in a World That Can't Stop Talking / Susan Cain 333 p.

If you're on the I team you're bound to enjoy this, full of research and anecdotes about all the ways being an introvert has advantages.  Primarily, but not exclusively, focused on the professional realm, Cain makes important points about why many American businesses with open collaborative workspaces may actually be minimizing their companies' creative output by forcing introverts into environments where they can't get anything done.  I especially liked the chapters on chidren and education.  If you can remember being irritated with group work as a kid in school, Cain's observations will come as no surprise.  She argues that with today's increasingly heavy emphasis on collaborative learning we may be leaving a generation of students behind.
