The human brain has a tendency to use shortcuts to simplify the process of analyzing and processing information. Using these shortcuts, the brain can estimate an answer but also make it difficult for investors to discern the right information, leading to incomplete or even wrong conclusions. For example, in the recent banking crisis, some investors have sold off quite a few bank stocks, and are very worried about the collapse of the market. Currently, the impact of the banking crisis is still limited. We need to keep watching and make decisions later.
