I think there’s hidden magic in the setup as well—knowing whether to assign probabilities or calculate EV in a given column (alternately, knowing whether to branch location to weather or weather to location). Understanding causality of “decision” and “outcome” is the subject of much discussion on the topic.
Good point. You could also say that even having the intuition for which problems are worth the effort and opportunity cost of building decision trees, versus just “going with what feels best”, is another bit of magic.
