The natural human tendency to hold opinions that agree with one's own point-of-view as more valuable than opinions that do not. However, this can be magnified to an insane proportion in ignorant people, overly-religious people, people who have power, people who think they have power, people on a power trip, and people who hate criticism in general. This may stem from a fear of change, what one does not know, or from an OD god complex.
Most 4chan users have an off-the-wall confirmation bias.
