Economics should study the human behavior of rationality. People can be impulsive and short sided because they are confident in their own abilities. Because of this, consumers often buy things they have only seen once, just because it caught their attention. Economics should study this in order to have a better understanding of human behavior. Economics should also study inconsistent behavior. Somebody could want one thing one day and something completely different the next. There could be a variety of reasons somebody changes their mind on something, therefore, it would be a very important trait to study. In your responses, comment on at least two of your peers' posts and share example of how non-rational human behavior can change an economic outcome
