Welcome to Litsy!

What�s the point of knowing anything when facts are so easy to look up? Just reach for your computer, tablet or mobile and ask the sky. We�re living in the golden age of rational ignorance where more people know who Khloe Kardashian is than who Ren� Descartes was and most of us can�t name the largest ocean on the planet. Yet the latest research indicates that the better informed are healthier, happier and often dramatically wealthier. Bestselling author William Poundstone conducts a hilarious and humbling investigation into the true worth of knowledge. What does it tell you, for example, when those who can pinpoint a country on a map are less likely to favour invading it? Underpinned by big data analysis and illustrated with eye-opening anecdotes, Poundstone�s Head in the Cloud is an entertaining manifesto on the surprising benefits of broadening your horizons, as well as a warning of the dangers of an ill-informed electorate.
