The human brain, including the brains of experts, spontaneously underestimates variance. In addition, the CFOs were asked to give their best guess of the 80 percent confidence interval for the estimated returns by estimating a value for returns they were 90 percent sure would be too low and a second value they were 90 percent sure would be too high, with 80 percent of returns estimated to fall between these two values (and 20 percent outside). In one experiment, the Chief Financial Officers (CFOs) of large US corporations were asked to estimate the return next year on shares in the relevant Standard & Poor’s index (Kahneman 2011: 261).

Availability is influenced by the recency of memories and by how unusual or emotionally charged they may be, with more recent, more unusual, and more emotional memories being more easily recalled. Overconfidence bias is fed by illusions of certainty, which are fed by hindsight bias, also known as the “I-knew-it-all-along effect.” Availability bias - the tendency to overweigh whatever comes to mind - similarly feeds overconfidence bias. 2002, Moore and Healy 2008, Proeger and Meub 2014).* Overconfidence bias is found with both laypeople and experts (Fabricius and Büttgen 2015). People have been shown to be prone to what is called the “illusion of certainty” in (a) overestimating how much they understand and (b) underestimating the role of chance events and lack of knowledge, in effect underestimating the variability of events they are exposed to in their lives (Pallier et al.
