Guest post: With bad science of their own

Originally a comment by Bjarte Foshaug on Playing a skeptical maverick.

As I have said many times, I cut all ties to Movement Skepticism™ specifically because of the misogyny issue, but now I don’t even think the movement did very well on the science front. For example skeptics tended to let climate change denialists (some of whom were even considered “thought leaders” of the movement) off the hook far too easily, and enter false balance territory whenever the issue came up, while congratulating themselves on how clever they were for not believing in homeopathy or Bigfoot.

The Movement also includes some of the most staggering examples of the Dunning Kruger Effect ever seen. Even the smartest, best educated, most knowledgeable person who ever lived, is only personally familiar with <<1% of all the scientific knowledge that’s available, and of that very tiny fraction <<1% is first-hand knowledge, And yet it’s quite common to hear skeptics talk as if they had personally done all the science (or even derived all of science, mathematics, epistemology, logic etc. from first principles without ever taking anything on trust) when all they’re really doing is repeating back half digested, half understood layman’s explanations from books, blogs, podcasts, YouTube videos etc. We see this whenever skeptics tell others (guilty as charged!) to just “follow the facts where they lead”, “let the evidence speak for itself” etc. which makes is sound like “following the facts where they lead” were a straightforward matter rather than something that requires vast amounts of experience and accumulated pre-knowledge in its own right. The truth of the matter is that the evidence never speaks for itself. As I have previously written, I could probably provide a decent layman’s explanation of the evidence for things like evolution or climate change based on books I have read, but I wouldn’t personally be able to derive any useful information about past climates from tree-rings or ice-cores.

I remember reading an article (I wish I could remember by whom) about skeptics debunking pseudoscience with bad science of their own. The author made the point that while self-identified “pro science” types may be more likely to reach a (somewhat) accurate conclusion than others, it doesn’t mean that their methods for arriving at those conclusions are that different from those of their opponents. It’s just that rooting for “Team Science” confirms their particular tribal identity. As much as movement skeptics like to think of themselves as Spock and elevated above all that touchy-feely “value” stuff, it seems to me that true critical thinking is at least as much about attitude as it is about skills. Without the proper self-questioning attitude acquiring the tools of critical thinking only gives you more excuses for rejecting any conclusion you happen to dislike for ideological, tribalistic or purely self-serving reasons.

Also, it now seems to me that skeptics have developed a few myths of their own. E.g. we’ve all heard how the system of (pre and post publication) peer review ensures that only those ideas that can withstand the most merciless criticism and attempts at falsification survive in the long run. My current understanding from reading about the replication crisis etc. is that the peer-review process often fails and in most cases no replication is ever even attempted. We have also heard how scientists like nothing more than having their pet theories disproved because it means there’s something new to learn, “it gives them something to do” etc. I think Max Planck was probably closer to the truth when he said that “A new scientific truth does not triumph by convincing its opponents and making them see the light, but rather because its opponents eventually die, and a new generation grows up that is familiar with it”.

Another commonly heard trope is the idea that freeze peach guarantees that the best supported ideas will rise to the top in the marketplace of ideas. The unstated – sometimes even stated – premise being that those who have science and logic on their side always enjoy a decisive advantage in the battle for public opinion. This never seemed right to me, even in my movement skeptic days. If critical thinking should have taught us anything at all, it’s that the strongest indicators of truth vs. falsehood – objectively speaking – rarely coincide with what seems most subjectively persuasive to laypeople. Playing by the rules of science is nothing if not limiting, while the purveyors of bullshit are free to say whatever will impress people. Without the necessary pre-knowledge and critical thinking skills all your average layperson can be expected to get out of the exchange is that one side comes across as far more assertive, aggressive and confident while the other side is forced to use conservative language (“seems to indicate” etc.), acknowledge uncertainty, and introduce caveats, conditions and qualifiers at every turn. No need to specify which side is the scientific one.
