the more refined your intuition, and the 'smarter' your feeling of rightness, the less you need to explicitly spit out logical chains for reasoning. a problem here is the division between system 1 and system 2, while in reality, those are more on a continuum.

while reasoning is often understood as logical argumentation, what it actually means is using "good sense" which is broader than mere logic. a certain form of steeredness is required, but I don't think you can reduce it to cold rationality. In German we call reason "Vernunft", which has an important affective component.
You can also understand it as controlled thought, using some kind of affective marker to distinguish 'good' vs 'bad' thought.
The important part is that it does something and happens as part of fluid intelligence. It's changing knowledge, that is key, whilst changing it according to some standard, which can be logic and often is.
