Things you need to stop doing in debates: framing your position as “rational/skeptical” and the opposing position as not “rational/skeptical.” What I’m talking about specifically are rhetorical moves like these: “Some hysterical people think sexual harassment is a huge problem, but I’m going to be rational about this.” or “I’m an actual skeptic, so I’m not going to whine about some so-called ‘rape culture.'”
Of course, some positions are truly anti-skeptical and/or irrational, but in that case, you can show why they’re not with evidence. For instance! “Anti-vax is an irrational position because all the evidence shows that vaccines are really useful, and no credible study shows that vaccines cause autism.” Or! “It’s not very skeptical to say that mental illnesses are just made up by Big Pharma. Have you spoken with people who have mental illness? Have you researched its neuropsychological correlates?”
But it’s not sufficient just to say something like, “I’m a Real Skeptic so I believe X.” or “You only think Y because you’re being irrational.”
First of all, even assuming for a moment that you, personally, are thinking rationally/skeptically, the fact that your opponent disagrees with you does not necessarily prove that they are not thinking rationally/skeptically. Shockingly enough, rationality and skepticism, when applied to the same issue, can still lead to wildly different conclusions! Some people have studied the evidence and think religion is good for mental health in general. Other people have studied the evidence and think religion is bad for mental health in general, or that its good effects are moderated too much by other factors. Some people have studied the evidence and think that it depends. All of these positions may be products of rational thinking. However, one or more of them may still be wrong, because rationality is not a panacea. It’s just a useful process that often produces good results.
Second, by painting yourself as a True Skeptic/Rationalist and your opponent as a hysterical over-sensitive irrational whiner, you’re engaging in a cheap rhetorical ploy that doesn’t actually 1) prove your point or 2) falsify your opponent’s point. It simply attempts to curry favor to your side through the use of buzzwords like rationality and skepticism.
What you are doing, oh person who probably loves to bloviate about logical fallacies, is begging the question. “I am a rationalist and you are not because my position is right and yours is wrong. My position is right and yours is wrong because I am being rational and you are not.”
Somewhere within whatever issue you’re attempting to needlessly obfuscate lie falsifiable claims that you’re simply ignoring. For instance, if rape culture does not exist, you would not expect rape to be treated more leniently than other crimes. But it is. If rape culture does exist, you might expect rape victims to be blamed for their rapes more frequently than other crime victims are blamed for the crimes committed against them, and they are. If rape culture does not exist, you might not expect people to feel sorry for rapists who have their “lives ruined” by being accurately accused of rape, but they do. If rape culture does not exist, you might expect all rapes to be treated as equally “legitimate,” but they are not. The point is not which of us is being “rational” about this and which of us is a “True Skeptic.” The point is, in which direction does the evidence generally go?
And when scientific evidence has not been accumulated yet, there are still ways in which you can think rationally about the issue. Someone yesterday demanded me to find them statistics on the frequency with which white people touch the hair of people of color without their permission. First of all, if you expect such a study to come out of an American research university, you simply don’t understand how underrepresented people of color are as university faculty, and how unlikely white people are to just spontaneously choose to study an issue such as this (although perhaps it’s happened, I’m not a human research database). Second, riddle me this: if it is not the case that white people frequently touch the hair of people of color without their permission, why does basically every person of color say that this has happened to them? Why have many of them written blog posts and articles about this? Do you think people of color just got together in some secret cabal to plan a conspiracy in which they accuse white people of constantly touching their hair without permission? If so, what motivation do they have for doing this? You’re a Skeptic/Rationalist, aren’t you? By all means, propose an alternative hypothesis to explain this!
Calling yourself skeptical/rational is not enough to make you so. Calling your opponent anti-skeptical/irrational is also not enough to make them so.
P.S. This is only tangentially related, but if you’re a man arguing with a woman and you’re leaping to call her “hysterical” and “irrational,” pause for a moment and consider the historical and cultural implications of this.
