Craziness
Funny YouTube videos, where Americans in cars can't answer super simply questions: "if you're driving 80 miles pr hour, how long dos it take to drive 80 miles?". The girl just can't figure it out.
Wondering how this works, trying to imagine how someone is not able to answer this question, was weird but essentially easier than I thought. I know, and everyone else I think too, what it feels like to just not understand something for a while, even though it turns out to be super simple afterwards. The trick is that the truth/logicality of something is never "obvious" or "instantaneous". It always requires an active component, and specifically a learnt, acquired, memorised active trick, of thought.
Thought and association are constructed, and can be, and are, constructed differently. Consensus shapes common associations, and culture accommodates common thought processes. But let's not forget how specific these conditions are.
