Thinking - Fast and Slow
Daniel Kahneman
Contributed by Larisa Brooke
Chapter 9
Summary

The average functionality of one’s mind is presuming that one is acquainted with skills and basic knowledge regarding a given problem. Kahneman uses this chapter to provide an informed opinion on the manner in which people face questions in their daily life. First, he introduces the reader to the substitution questions concept, which entails a tendency of the mind to act with a bias when answering a question. A typical person will substitute a problematic issue with one that is relatively easy to explain or handle. Second, the author sheds light on a model that he refers to as The 3-D Heuristic, which involves a convincing illusion of the mind that invokes an individual to diverse from accuracy. Kahneman emphasizes the Heuristic concept using several illustrations. Also, the author delineates the characteristics of System 1 in this chapter.

Analysis

Typically, the mind tends to evade complex situations and challenging questions but does not end at that. There exist some ways that the brain sidesteps complexities as described in this chapter. System 1 offers the primary platform where one assesses the viability of a situation as well as alternative actions. The characteristics of System 1, as Kahneman puts it, are suggestive of various activities and decisions that people make. One can see the difference of levels of operations executed by individuals based on these features.
