Context: The problem lies in the psychology of human judgment . Much research going back to the classic work by Kahneman and Tversky demonstrates that when people make a judgment about some topic with which they are not expert , they tend to use a strategy called " anchoring and adjustment . " First , people access a belief ( which serves as the anchor ) and then adjust that belief to take into account additional factors . This strategy is remarkably effective in most situations .
