Interesting concept. I have recently published a book on political polarization. It is called Engineering Unity. In this book, I portray both sides of a political topic and then illustrate a centrist view. After watching this video, I did some introspection on why I believe what I do. My first leaning is often away from groupthink. If the masses think the world is warming, I question this idea. In my book, I do respectfully illustrate why each side is rational in their belief. Even, if that belief is different from my own. I am an engineer by profession and believe I have good critical thinking skills. Sometimes I wonder if I just have a critical spirit :)
