According to the model, underlying cognitions or subjective judgments are identical with noise or objective observations that can lead to overconfidence or what is known as conservatism bias—when asked about behavior participants underestimate the majority or larger group and overestimate the minority or smaller group.
So noise reduction could be a bad idea in these judgments, he argued. [27] Anticipating this critique, Kahneman, Sibony and Sunstein write in the book that noise reduction should ideally be followed by decision makers using the now-better judgment data together with their values and potential risk-avoidance criteria to make the optimal choice.
