Time Preference Rate. “The Marshmallow Tale” by Joachim de Posada and Ellen Singer describes the “Marshmallow Experiment” at Stanford University. The experimenter left the child alone in the room and gave the child a marshmallow, instructing the child to eat it immediately. However, if the child did not eat it within 15 minutes, the experimenter would give the child another marshmallow. Some children waited the full 15 minutes, while others stopped waiting early. These two groups were followed for 14 years, and as a result, the more patient children showed better social and mental abilities. Those who cannot tolerate waiting are said to have a high time preference rate, while those who are patient are described as having a low time preference rate. In investment, high and low time preference ratios are not necessarily good or bad because many investments depend on luck. The key is to find and stick to methods and principles that match one’s own tendencies. - Joseph’s “just my thoughts”
British anthropologist Robin Dunbar was certain that primate cerebral neocortical capacity determines the number of social relations. He definitively established the limit of human relationships at 100 to 230 people. The average value of 150 people is known as Dunbar's number. In the world of chimpanzees, 30 is the absolute maximum. However, fewer than 12 people in the world can sympathize with me. My best friend is now reduced to 3 or 4. The relationship quantity decreases to the square root value and increases to the square value. Three or four of my best friends will eventually connect with people from all over the world. This is the same principle as when one or two virus-infected people infect the world. Focus on your best friend. - Joseph’s “just my thoughts”
