Most human brains just aren't very good at coping with abstract concepts. It reminds me of the Wason selection task[1]. You give participants a formal logic problem to solve, "how many cards do you have to turn over to show that the rules are being followed". If the rule is "a card with a vowel on one side _must_ have an even number on the other", people do very badly making illogical assumptions. If the rule is "one side has a bar order, and the other side has the age of the person making the order. The person must be above the legal age", it makes sense and people do well, because we understand bars, drinks and the laws thereof.
