This week was a big learning week, covering the subjects of psychology and finance. Never knew this before, but there is System 1 thinking that is fast, and there is System 2 thinking that is very deliberative and slow. Each has particular strengths; but if you use System 1 thinking to solve a System 2 problem, you will be making big mistakes for sure.
What is System 1 thinking? It is fast thinking, on the spot analysis. Examples include when asked what 2 plus 2 equals, you already know the answer. If a car jumps out from a red stop light, you know to hit the brakes. System 1 is very fast and often accurate, but not without its pitfalls.
System 2 thinking is involved thinking, that is slow and takes some time. It is the type of thinking you use to solve not immediately apparent solutions to important decisions or questions. An example of System 2 thinking is if asked the question: What is the answer to 24 times 43? You do not know on the spot; you need a calculator. Other System 2 questions are: should I really buy that car, or house, or invest in that company, or marry that special someone? These problems need System 2 slow thinking, to increased the probabily of getting it right.
These ideas are those of Professor Daniel Kahneman in his book on behavioral finance. His conclusion is that folks use System 1 thinking too much to solve System 2 problems, leading to financial problems. So, rather than impulsively buy that stock or car or whatever, give it some time. Wait a day or two. Run all the numbers. Analyze the Probabilities and Possibilities. In other words, slow down your thinking and problem solving on the bigger topics. You will do much better than using on the spot instant System 1 thinking.
This is a huge topic today, because it applies to investing. So much investing is done using System 1 impulsive thinking than a more deliberative approach using System 2. In fact, guys are more prone to System 1 thinking in System 2 finance situations according to the professor, shown below.

According to the professor, when it comes to stocks and bonds, you might as well turn off all the cable tv finance channels and all the web cast instant-oriented stock market analysis too. All it does is really confuse you. He says you should not even look at at stock prices but maybe once every three months. Not kidding.
The reason this is all known is that the folks at the CFA Institute kindly broadcast their plenary sessions for free to the public this week, using the internet. CFA Folks in the room paid $1000+ plus hotels to attend the professional conference, but us websters could watch the main courses for free compliments of the CFA. By far the best session is the one-hour presentation by Dr. Kahneman. It is highly recommended, and especially for those with a finance bent.
Here is the institute logo and a link to watch this amazingly modest man talk about how our brains think, and how we can get in trouble when investing unless we do System 2 thinking. Yes, in some ways all this is common sense, but this man has put it all together in his book as theory and practice. The science is so sound, he got a Nobel prize for it. Remember the video lasts an hour.
