Predictably Irrational demonstrates how irrationality manifests itself in situations (often very peculiar and hilarious) where rational thought is expected.

In this astounding book, groundbreaking in scope and totally original, Dan Ariely cuts to the heart of our strange behaviors and presents outstanding material that will keep every reader transfixed. He explains why honor codes are actually effective in reducting dishonesty in the workplace, why a 50-cent aspirin can cure a headache that a one-cent aspirin cannot, and, ultimately, why we make decisions contrary to our better judgement.

Predictably Irrational will help readers make better choicesin their personal lives, their business lives, and about our collective welfare.
