Information asymmetry happens when buyers and sellers have different levels of information, leading to adverse selection in the market. Adverse selection occurs when one party, either the buyer or the seller, has hidden information about the product and makes buying or selling decisions based on that information. For example, in the used car market, buyers cannot know everything about the cars and cannot fully trust them. Because of this, they often try to buy used cars at lower prices to evaluate their quality. To make buyers feel more confident, sellers might promise to repair the car free of charge if it breaks within a year after purchase, protecting themselves against adverse selection. A successful transaction depends on strategies that align with the market’s specific characteristics. - Joseph’s “just my thoughts”
The "normal human body temperature = 37°C" standard was established in 1851 by the German medical doctor "Carl Reinhold August Wunderlich", who took millions of temperature readings from about 25,000 people and reported "36.2°C to 37.5°C". However, surveys in the United States in 1992 and the United Kingdom in 2017 found 36.8°C and 36.6°C, respectively. So in the past people deemed that the discrepancy was due to errors in old measuring equipment or methods. But Julie Parsonnet and her colleagues at Stanford University's School of Infectious Disease Epidemiology found a common thread in the temperature databases: People are cooler now than they were then. It wasn't just a measurement error. They speculated that medical advances had reduced inflammation and lowered the average temperature. We don't question the obvious. - Joseph’s “just my thoughts”
