Sutton’s Law states that you should spend your resources focusing on the most likely solution, rather than spending time and money looking into every possibility. It comes out of an apocryphal story that the bank robber Willie Sutton was asked why by a reporter he robbed banks, and he replied “Because that’s where the money is.”
Interestingly, Sutton claims that the reporter made that story up, and that he never said any such thing. Which leads to an interesting question: How many well-known laws or principles are based on a story about something that actually never happened?
As Yogi Berra once said “I really didn’t say everything I said.” By the way, Berra really did say that.
