Here’s an interesting video clip (18:15) of Malcolm Gladwell, staff writer for The New Yorker and best-selling author of The Tipping Point and Blink, giving a talk at the 2004 TED (Technology, Entertainment, Design) Conference. He talks about the nature of happiness with an entertaining tale about psychophysicist Dr. Howard Moskowitz, who revolutionized the food business by realizing there’s no such thing as the ‘perfect food’, just ‘perfect foods.’ Gladwell covers Moskowitz’s search for the ‘sweet spot’ in a new formula of Diet Pepsi, redefining Prego spaghetti sauce for Campbell’s, people’s differing coffee preferences and the advent of designer mustard. Gladwell also wrote about Moskowitz in The Ketchup Conundrum.
