Very often, when someone tells you that their positions derive from "reason and logic," it's a sign that they likely believe a lot of nonsense. This isn't because reason and logic have led them astray, but rather that they are in the habit of mistaking their own immediate intuitions for reasoned conclusions. There's a culture of assuming one is generally very smart, and so believing that one's first impression of a novel issue is the product of applied and careful intellect, and thus correct.

Elon Musk failing at Twitter is a good example of this. He can't grapple with complexity in fields he's ignorant of, because he has "logic and reason" on his side, and so what seems obvious to him must be true. This is also the baseline approach that defines much of what used to be called the Intellectual Dark Web, people who assumed their heterodox opinions must be true because they are masters of "logic and reason" and their heterodox opinions seem true to them.
