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”
Eco bags are not eco-friendly. In 2007, the eco-bags, which British designer Anya Hindmarch printed, “I’m Not a Plastic Bag” on canvas, sold out 20,000 copies in 30 minutes at a limited edition price of 5 pounds. The project reduced the use of plastic bags by 58% over the next two years in Britain. However, a survey by the British Environment Agency found that consumers used paper bags at least 3 times more to have less environmental impact than plastic bags and used eco bags 131 times more to help protect the environment. In 2018, Denmark also announced a study that indicated people used plastic bags at least 37 times, paper bags 43 times, and eco bags 7,100 times before being discarded to recover from pollution. Yes, the facts that people believe have cheated us all. Materials and consumption are necessary, but people belatedly realized that environmental protection should also consider product use cycles and production. - Joseph’s “just my thoughts”
