Background: “Learning” vs “Learning About”

Adaptive systems, reinforcement “learners”, etc, “learn” in the sense that their behavior adapts to their environment.

Bayesian reasoners, human scientists, etc, “learn” in the sense that they have some symbolic representation of the environment, and they update those symbols over time to (hopefully) better match the environment (i.e. make the map better match the territory).

These two kinds of “learning” are not synonymous[1]. Adaptive systems “learn” things, but they don’t necessarily “learn about” things; they don’t necessarily have an internal map of the external territory. (Yes, the active inference folks will bullshit about how any adaptive system must have a map of the territory, but their math does not substantively support that interpretation.) The internal heuristics or behaviors “learned” by an adaptive system are not necessarily “about” any particular external thing, and don’t necessarily represent any particular external thing[2].
