I'm not sure a lack of intuition implies a lack of reasoning. They clearly didn't make that jump until they were told to look for something, but did pretty handily once asked. Clearly they used some version of reasoning to do that, but just as clearly had no interest in it at all until directed to look for it.

I wonder if we phrased it differently we could get them to make the leap without so much hinting? I'll tinker with it a bit later.

Either way, very cool experiment! Thanks for posting it. I'd upvote you again if I could.
