It is not just that, it is more detailed let me post a link to help you understand the psychology behind it. The Backfire Effect. When you start to pull out facts and figures, hyperlinks and quotes, you are actually making the opponent feel even surer of his position than before you started the debate. As he matches your fervor, the same thing happens in your skull. The backfire effect pushes both of you deeper into your original beliefs. The more difficult it becomes to process a series of statements, the less credit you give them overall. During metacognition, the process of thinking about your own thinking, if you take a step back and notice that one way of looking at an argument is much easier than another, you will tend to prefer the easier way to process information and then leap to the conclusion that it is also more likely to be correct. In experiments where two facts were placed side by side, subjects tended to rate statements as more likely to be true when those statements were presented in simple, legible type than when printed in a weird font with a difficult-to-read color pattern. Similarly, a barrage of counterarguments taking up a full page seems to be less persuasive to a naysayer than a single, simple, powerful statement. Have you ever noticed the peculiar tendency you have to let praise pass through you, but to feel crushed by criticism? A thousand positive remarks can slip by unnoticed, but one “you suck” can linger in your head for days. One hypothesis as to why this and the backfire effect happen is that you spend much more time considering information you disagree with than you do information you accept. Information that lines up with what you already believe passes through the mind like a vapor, but when you come across something that threatens your beliefs, something that conflicts with your preconceived notions of how the world works, you seize up and take notice. Some psychologists speculate there is an evolutionary explanation. Your ancestors paid more attention and spent more time thinking about negative stimuli than positive because bad things required a response. Those who failed to address negative stimuli failed to keep breathing. This process is known as biased assimilation and is something neuroscientists have also demonstrated. McRaney cites the work of Kevin Dunbar, who put subjects in an fMRI and showed them information confirming their beliefs about a specific subject, which led brain areas associated with learning to light up. But when faced with contradictory information, those areas didn’t fire — instead, parts associated with thought suppression and effortful thinking lit up. In other words, simply presenting people with information does nothing in the way of helping them internalize it and change their beliefs accordingly.

So yeah **"THE BACKFIRE EFFECT **IS WHY PEOPLE REFUSE TO BELIEVE THIS IS HAPPENING
