In The Drunkard's Walk: How Randomness Rules Our Lives, Leonard Mlodinow shows just how unreliable polls, grades, sports statistics and wine ratings are. According to a recent Los Angeles Times article, wine judges at the California State Fair did not give the same wines identical ratings when tasted multiple times. Mlodinow argues that wine ratings and scores are arbitrary and the results can be explained by theory of randomness.
Mlodinow, who has a PhD in Physics from the University of California, Berkeley, has written scripts for MacGyver and Star Trek: The Next Generation.
