The rationality study has an interesting and I think compelling critique in a later issue (and a third short response from the original authors).

Sun (2022) argues that Scheffer et al (2021) is confusing language colloquialism with changes individualism and rationality. As more people learned to read and write, writing styles evolved (a more oral style of writing as one example). Scheffer et al (2022) in their reply say that their story better fits the timeline and is robust to these forms of language changes (colloquialization and others mentioned).

This isn't my area at all, and I'm not even sure what methods are common here. But my gut reaction to the PCA and trends in Scheffer et al was a bit of skepticism, I guess? It's more complicated than that, of course. I don't see how that accounts for changes in who is reading and who is writing? As literacy expands, then does that matter for the story?

Here's another thought, writing and publication technologies must have evolved over this time as well? Nietzsche has some complaint about his writing tool affecting his thinking.

I'm enough of a Neil Postman fan to say there's something interesting in language and, specifically, the switch from oral communication, to written, and then back. There's a lot of work to do here. I know Postman alleged this story, but is it even correct? How do you really measure this? What does time use survey data say about reading and writing?
