Dunning Kruger Effect


“The trouble with the world is that the stupid people are cocksure and the intelligent are full of doubts”

- Bertrand Russell

To put it crudely, the not so smart people are not so smart enough to know that they are not so smart.

Alright, I’m not trying to be an elitist over here. This post is probably an extension of curse of knowledge. So while there is a trouble of knowing too much, on the other hand, knowing too little may make us inflate our own capability. Nonetheless, it is a true cognitive bias that we have.

There is also another saying that still water runs deep. This is why the real smart people are those who keep quiet most of the time as they tend to have some unfulfilled doubts that they are unsure of. Obviously, we all know about people trying to be smart aleck.

So what’s the purpose of this article?

In the stock market, there is this group of people called the sucker class. There are many annoying issues about them but the most annoying one is that they talk a lot and love to give stock tips. These are the people who also think that they know but actually they don’t.

On the other hand, the most intelligent people tend not to be able to excel in the investment world. I would certainly consider some professor as really intelligent about the world. Quite a while back, a professor was telling me that the knowledge of Jim Rogers is minimal in the academia world. I was shocked. It takes a lot to mention that a billionaire investor such as Jim Rogers is wrong with his economics judgment. Nonetheless, I will not reject the notion. In fact it is more likely to be true. That is probably the issue with really smart people who don’t usually make it in the stock market. Issac Newton is one such example. He lost a huge sum of money during the South Sea bubble. He could not understand the madness of the crowd back then.

I guess there is something more about real successful investors.

Linux

Why do some people choose to run Linux as their PC platform of choice while others opt instead for other ways of running their computing experiences?

Is it market share, perceived ease of use, slick marketing overtures, users wanting to use what they already know? This list might explain why people might choose OS X or Windows.

But what approach to computing (and life) prompts a person to use a Linux box on a daily basis? I’ll share my insights based on personal experiences and other observations accumulated over years of living the Linux lifestyle full time.

Software buyer’s remorse has gone M.I.A.

I haven’t spent my hard-earned income on software in years. I own one single (legal) copy of Windows XP Pro that I use for work purposes (software testing) in VirtualBox.

Does this mean that I choose not to spend money on Linux then? Not at all. I do in fact, donate money to specific Linux-related projects on a regular basis.gold jewelry charms

Smart in their own ways..

I would not say the Prof are smarter than the Jim Rogers or Jim Rogers is smarter than them. I think they are smart in their own ways. Those prof are very smart in their own field of research but they are not good in the stock market. While Jim, on the other hand, have the ability to spot trends way ahead of the normal folks, so he is smart in these area. He may get some of the economics theory or concepts wrong, but, econs in itself has such so many school of thought that it may be right in one school and wrong in the other school.

While Newton is smart in science, he is just not good at investment. Or, maybe his time is devoted in science that he don't have enough time for understanding how the market works.

So, all these great people, either Jim or the Prof or Newton, they are smart but in different field. 

Not so smart

Well, I once heard from my professor that sometimes it pays not to be so smart. In a stock market, if you can predict the stock prices in 5 years time while the market prices in maybe 1-2 years time is not in favour of your prediction, you are on the losing end. It is maybe not that you are wrong but it may be that the people in the market might not be so smart. No matter how smart you are, you can't beat the market unless you can predict how smart people are in the market. Thus, just be smart but not any smarter than the market. Make sense?
