More people know who Khloe Kardashian is than who René Descartes was, and most can't find Delaware on a map, correctly spell the word "occurrence," or name the largest ocean on the planet. But how important is it to fill our heads with facts when a few keystrokes can summon almost any information in seconds? The author of Are You Smart Enough to Work at Google? confronts that question in this hilarious yet humbling book, demonstrating that many areas of knowledge correlate with wealth, health, and happiness, not to mention politics and behavior. Combining survey techniques with eye-opening anecdotes, William Poundstone examines what Americans know (and don't know) on topics ranging from quantum physics to pop culture—and assesses what that really says about us.
