We reinforce these biases by regularly consuming information from those we agree with and regularly denouncing the beliefs of those who disagree with us. This is what causes the liberal/conservative dichotomy we see in the world where both sides are fundamentally convinced that the other side is the root of all evil and that only an idiot would follow the beliefs of them. The result of this is notably a blanketing of complete misinformation.
While I could go on about the 2016 election in the United States, the best bet is to give you a test and show you what I mean.

Legalizing drugs would give more wealth and power to street gangs and organized crime.
Mandatory licensing of professional services increases the prices of those services.
Climate scientists believe that if the north pole icecap melted as a result of human-caused global warming, global sea levels would rise.Answers: true, true, false, false, false, true, false

Did those answers surprise you? You may have noticed that the first six are very much politically inclined, and your incorrect responses could lead to a prediction of your political leanings. Getting the first, fourth, and fifth wrong would suggest that you are Left leaning, while getting the second, third, and sixth wrong would suggest you are right leaning. Getting the last one wrong would show your general misunderstanding of climate change science. If that statement were true “your glass of coke would overflow as the ice cubes melted. It’s icecaps on land that raise sea levels when they melt.” (Pinker)
While this ignorance should surprise you, it is important to note what is going on here: it is not that members of the left are particularly less educated than members of the right, but that both of them are near equally ignorant of important topics. These blinders that we have attained through our political leanings can give considerable light into our rejection of progress in human life.
In Enlightenment now, Steven Pinker argues that not only have we mainstreamed a sense of doom, but we have embraced it to a point where we are unable and unwilling to see what progress has come over the past 200 years. He calls this Progressophobia, the fear of progress.
