maybe a decision tree with reasons, compared to a decision tree of simple world states, could be considered a decision tree where the decision is backed by a theoretical fully expanded decision tree. a drawing of recursion.
humanly, we summarize our world states into patterns. a pattern is roughly analogous to a huge set of expanded states bearing a consistent similarity. when we use a pattern in a context, we are proposing that the context bears the same similarity and behaves the same way as all the examples used to form the pattern. with A+B and B++, there is a pattern where
