A DECISION SCIENTIST USES A DECISION TREE.

A DECISION SCIENTIST USES A DECISION TREE. Memory from forty years ago says that Howard Raiffa, one of the giants of decision science, once said in class that he had asked Kenneth Arrow, a future Nobel Prize winner, whether he had used a decision tree when he had accepted a position at a different university. Arrow had not. Raiffa said that before taking a different position, he had in fact used a decision tree. And then he had slept on the decision to see whether it felt right. The last step is important.
