PBS NewsHour's piece on confirmation bias and addiction to it in our political news:
https://youtu.be/64A-x8LnX-I
What is interesting about the people interviewed is that they know something is amiss with their addiction to the material, and they are willing to admit that, as well as admitting that the material is manipulative. However, they are insistent in their denial of being influenced, and keep repeating that they have always held their beliefs and that what they believe came from within themselves, which I don't buy.
