Indeed. It's amazing how many self-described rational people fall back on "I've never seen it, therefore it doesn't exist and you are lying" when it comes to uncomfortable or challenging questions. It's very easy to end up performing a kind of rationalism identity politics, especially when men end up defending "rational" men from "irrational" women.

(From a quote within the article)
I disagree, having known a lot of smart people. There's definitely a skill of being able to step back from a situation and look at it from other angles. That doesn't mean people apply it by default to themselves. Nobody likes rationally evaluating their own flaws. Some of the smartest people I knew had chaotic personal lives because of this.
