“There's a subtle difference between the desire to have been right and the desire to be right. The desire to have been right prevents us from seeing the real truth, causing us to hold on to ideas that might be illogically and factually flawed. We failed to see how we were wrong, and so we failed to learn and grow. We hold on to beliefs that we have been surrounded by so much that we start to seek out evidence to back up our bias and not to find out the truth. There is no progress without change, and there is no change without admitting there's a problem in the first place.
The truth is that humans find it very difficult to process information in an unbiased and rational manner once they've developed strong feelings or sentiments about the issue, so people interpret everything they see in a way that already agrees with everything they know and believe about the world.

Some people believe in something called extrasensory perception. So, for example, they remember all the times they were thinking about their mom and picked up their phone only to see that she was calling. It seems like fate in a way, but yet they forget all the times when mom called when they weren't thinking about her and the other times when they were thinking about mom, but she never called. Because they believe so strongly in extrasensory perception, they are far more likely to remember instances that back up their claims, even when the instances that don't agree with those claims occur far more frequently, making their confirmation bias even worse.”
