This chapter is a rather continuation of the previous chapter and focuses on wealth as a factor with which the mind is conscious. Kahneman acknowledges the research of renowned economists such as Harry Markowitz, from whom he borrows the theory of wealth. The author highlights the manner in which the mind assesses outcomes, particularly in wealth. Kahneman offers an analysis of three approaches to explain the underlying factors of his philosophy. They include loss aversion, diminishing sensitivity, and the adaptive concept.
