sometimes there are certain things that is so obvious for me,

but I find it hard to get the idea across to other people, then I tried to think from their angle, I guess whatever books, ideas, or theories people pick up at the beginning has the fundamental influence on their view on the subject, be it science, stock markets or life itself. Later on, it is hard to say who is really biased, me or other people. Also, there is no way to test it out, even if you are successful, it does not mean you are necessarily right since your personal life is such a small sample size. But I know there are people who never question the probability whether their view maybe wrong, I do not know if this is a blessing or just plain dumb.
