I mean, what is crystallized intelligence, but that which we can call upon without having to focus on it? I mean this honestly, no snark. When I was a kid, learning how to factor numbers was really hard. It took a lot of time and concentration to do even basic problems, and people who could do it quickly without much perceived effort were a mystery to me. By the time I reached high school, I had enough practice that I recognized the common patterns without difficulty, and often the answer bubbled up to my conscious mind without thinking about it at all. It sure feels like my brain is making an API call to a subsystem, you know?
