Confirmation Bias « You Are Not So Smart
Over time, by never seeking the antithetical, through accumulating subscriptions to magazines, stacks of books and hours of television, you can become so confident in your world-view no one could dissuade you. Remember, there’s always someone out there willing to sell eyeballs to advertisers by offering a guaranteed audience of people looking for validation. Ask yourself if you are in that audience. In science, you move closer to the truth by seeking evidence to the contrary. Perhaps the same method should inform your opinions as well.
