They're not systematizable ever. We're talking about experiences unique to each individual. If you get 30 kids sitting in a classroom they share the room they're in and the words the teacher is saying. They don't share how much attention each one is paying, they don't share the same comprehension or interpretation of the content, they don't share the way they feel about the content, they don't share the thoughts they have about the content and they don't share the new connections made in their brain as the lesson progresses. You can't systematize that. It's random.
