In a funny and insightful interview on The Daily Show, John Stewart questioned Jim Kramer about the contradictory content on CNBC. Kramer admitted that they have to fill in the 17 hours of live TV every day. This highlights a common problem in the industry where experts feel the need to say something even when there is nothing to say. This pressure to appear complex and valuable often leads to mistakes. The gap between expertise and practical skills can have serious consequences. This applies not only to medicine but also to investing, as shown by the fact that many professional investors don't own the funds they manage.
A truth that applies to almost every field is that it’s possible to try too hard, and when doing so you can get worse results than those who knew less, cared less, and put in less effort than you did.
There are mistakes that only an expert can make. Errors – often catastrophic – that novices aren’t smart enough to make because they lack the information and experience needed to try to exploit an opportunity that doesn’t exist.
