This is another great TED Talk on Denialism. It was given a few years ago but I highly recommend it!
Fantastic Ted Talk video on science denial. It applies equally to all denial and anti-science movements: climate denial, food conspiracy, Big Alterna and Big Organic, creationism, anti-vaccine cranks and many others. Please watch the video because not only does he do yet another necessary takedown, he also shows the intimidating actions used by some anti-science groups.
