One of the key principles of money is ‘opportunity cost.’ It means that when I buy something, I have to give up something else in return. We think we buy because we need something, but we often forget that we could buy something else instead. We rarely consider ‘opportunity cost’ when making a purchase. We do not compare other values against our needs. Buying something means giving up something else, but we often don’t realize it. When we spend money, we should also consider the ‘opportunity cost’; yet, in reality, we aren’t trained to do so. By making a purchase, we bypass the value comparison that may not offer any additional benefits. Maybe it’s because we lack knowledge, or perhaps the idea isn’t appealing. - Joseph’s “just my thoughts”
The social scientist’s method of confirming the facts is first to verify the beta error (Type II error) and then the alpha error (Type I error) before accepting the hypothesis as true. In other words, if the probability is less than 5% after focusing on the likelihood of accepting a false hypothesis as true (Type II error), then we risk rejecting a true hypothesis (Type I error) as false. It’s a conservative position that new information will be accepted only when the probability of being wrong is very small. This verification method is helpful if you don’t want to be swayed by conspiracy theories. - Joseph’s “just my thoughts”
