Information Only Has Value if it Could Change Your Decision

A recent article from the Bangor Daily News provides a colorful illustration of the principle, long known to decision analysts, that the value of information is zero if the information couldn't change your decision. "Man charged after he asked police for a Breathalyzer test, was told not to drive, then drove anyway" Just a reminder: whether you use a decision tree or not, make sure your decisions are based on all relevant information. You may want to pay special attention to information from your local police ;-)
