Certainty effect - sustany/dvg GitHub Wiki

A tendency to spend more time or money looking for information than justified by its probable value, simply because the decision�maker thinks it might turn some claim into a total certainty.� Thus, information that may increase�a probability�of something from 30% to 40% looks much more important if we have a chance to find it when the likelihood is already thought to be�90% (increasing probability from 90% to 100%).
