Just my thoughts #0627

The relativity of values causes us to use money irrationally. I go to the supermarket to buy a $15 pen, and the clerk smiles and says, “You can buy this pen for $7 if you walk 5 minutes from here.” Then, most people walk five minutes and buy a $15 pen for $7. But if you want to buy a $1,000 jacket and the clerk smiles and says, “You can get a $992 jacket in five minutes from here,” most people simply buy the $1,000 jacket. Reasonably, walking for 5 minutes equals the effort, and the profit of $8 is the same. However, people might go to a store that sells pens cheaper, but not for the jacket, because the discount rate is too low. In other words, the relativity of comparing values makes us act irrationally. The pen’s discount rate is 55%, and the jacket’s is only 0.8%. Yet, the total amount is the same for all $8, and the effort to gain that profit is identical. Attitudes and misconceptions about consumption influence how we build wealth. - Joseph’s “just my thoughts”

The Anchoring Heuristic In 1974, Tversky and Kahneman divided two groups and asked one group to calculate the value of "8x7x6x5x4x3x2x1" and the other group to answer the question "1x2x3x4x5x6x7x8" immediately. The average calculation result of the first group was 2,250, and that of the second group was 512. For both groups, the original answer is 40,320, which is the same. Although they multiplied by the same number, the first group multiplied by the order of the larger number, resulting in a higher baseline adjustment, while the second group did the opposite. When we judge and make decisions, the reference point determines the extent and direction of our illusion. When we live, we have to deal with these fallible human beings. - Joseph's "just my thoughts"
