Thinking - Fast and Slow
Daniel Kahneman
Contributed by Larisa Brooke
Chapter 12

Kahneman in the chapter named science of availability believes that we judge a case at hand from the frequency of a similar event from the past. Both systems are involved since one part is deliberate, while that of System 1 is automated. The availability of psychology states that when no background information is availed to System 1, one may not arrive at a decision. System 2 has a way of resetting expectations of System 1 to normalize an event that otherwise could have been surprising. The bias as a team one result of availability creates overconfidence where an individual who has had a series of success still believe in succeeding.


Intuitions based on available information may have a significant effect on the decision to be taken. The bias extends to the past experiences, and the brain does rely on the skills as though they are substantial and reliable sources. System 1 eases the collection of information on which reference is built. The chapter has a clear definition of the modes and methods the science of availability influences. The expectations can be regulated by the conscious System 2 controlling the way the brain thinks. Without the system, one availability bias effects can be so devastating since the estimations of System 1 could be so high.
