To expand on this: one major arrow in rationality’s quiver is that practically everyone (a few genuine postmodernists excepted) values some basic concept of rationality. If this weren’t so, then political actors wouldn’t get such mileage out of showing inconsistencies, biases and (purported) fallacies in their opponents.
Furthermore, the vast majority of people believe themselves to be epistemically rational, now excepting some fideists of various types as well (but even these usually have arguments for doing so that appeal to some sense of second-order rationality).
