Actually I also disagree with the title... not because it's wrong but because it will be coopted by the truly ignorant to "prove" that everything they disagree with has no scientific basis. This is the academic equivalent of clickbait, with the unfortunate consequence of being distributed outside the academic community.
I do think that the author has a point in that we are taught "best available" theory as fact. That's not wrong, however, it's only missing the concept that our school system has been ignoring for decades - actually teaching the basis of the scientific method, logic, critical thinking... not to mention applied statistics. All of these are necessary in the modern world to do the one important civic duty that most people exercise in a state of utter ignorance - voting.
I have pursued a rather rigorous scientific training career (MD, PhD) and getting the PhD training really altered my way of thinking about the world, and learning how to ask questions that are appropriate, can be answered, and how to design ways to answer them. I can understand where they author is coming from. I just think that to truly understand what he is saying one needs much more training than lay people get, and this headline just gets me into more trouble when I talk to patients and they refuse to believe me cause they read in the paper that everything science does is bollocks.
