Dubner, journalist and co-author of "Freakonomics: A Rogue Economist Explores the Hidden Side of Everything") "The leading researcher of tipping over the last few decades has been Prof. Michael Lynn, and I was very glad to see that after publishing numerous articles about tipping, he has now also written a book on this fascinating phenomenon.
