Belichick, Rationality and Why the Colts are 14-1
It’s fourth down with two yards to go. You’re facing the decision to punt the ball to Peyton Manning and Colts offense with a little over 2 minutes to play and giving your defense the chance to stop a touchdown drive, or to go for it and essentially end the game with a first down.
In the decision sciences we call this type of situation: “decision making under uncertainty”. Rational decision theory says that we calculate or estimate the likely probability of success in each scenario and we choose the option with the greatest expected utility. In this case, a rational decision-maker chooses the option with the highest probability of winning.
