Sudden thoughts

During my study on some foundamental statistic, finance and risk related issue, I randomly pick up the book that I am currently reading "A mathematician plays the market" and start reading a page taking about "confirmation bias".  It stated that people tends to search for information that supports their own belief and neglect those that are against them.  I believe there may be some minorities who may unintentionally search for info that are against them while ignoring those that favours them. Anyway still, the info that these people grasp are definitely bias.  Even there are wiser people who tend to read info with different standpoint, yet I believe due to the structure of human brains, they tend to have better memory on info that are favour their view.  That means the info is skewed either to the right or left if they are being classified upon favourness to ones thought.
The only way to minimize "confirmation bias" on the selected piece of info, it is important for us to organize the info and its implications to us via a scientific way.  Maths and statistic are one of the less non bias mean to help us to do so, despite it may have its only limitation.
