In a recent piece in one of my favorite mags, the New Yorker titled “The Sure Thing,” Malcolm Gladwell, the king of countering widely held American assumptions, wrote that risk taking is not actually a widespread quality among hugely successful entrepreneurs. In fact, it’s just the opposite. Major entrepreneurs like Ted Turner and John Paulson are in reality so risk averse that they take—or took, when accumulating their massive wealth—all possible precautions to reduce risk. Big-time entrepreneurs, Gladwell suggests, are not the kind of wild gamblers who, because they have the courage to take big risks, eventually make a lot of money. They are more akin to the MIT Blackjack Team, from the book “Bringing Down the House,” or the movie with Kevin Spacey “21,” who discovered the game of blackjack was legally beatable, if you applied certain mathematical principles to it.
