In this chapter, we motivated the rational model of information search by showing that rational people should prefer information that is accurate no matter how it relates to their current hypothesis. People should continue to seek new information until they are certain enough of the answer that the cost of new information is not justified by the degree of uncertainty. Confirmation bias can lead to overconfidence, where people fail to recognize the level of uncertainty they face. What implications are there for information search by those displaying confirmation bias? When will they cease to search for information? What might this imply regarding people who have chosen to cease their education efforts at various phases? What education policy might be implied by this result?
