You ever see a dog that’s got its leash tangled the long way round a table leg, and it just cannot grasp what the problem is or how to fix it? It can see all the components laid out in front of it, but it’s never going to make the connection.
Obviously some dog breeds are smarter than others, ditto individual dogs - but you get the concept.
Is there an equivalent for humans? What ridiculously simple concept would have aliens facetentacling as they see us stumble around and utterly fail to reason about it?
Probability is a big one for me that I can’t wrap my head around because the rules just don’t seem to line up with reality. Like, if I roll a die 10 times and get 6 all 10 times, what is the probability of me rolling 6 again the next roll? It’s 1 in 6. But that’s insane. I just rolled 6 10 times in a row. That’s so wildly unlikely, it feels wrong that the odds I’d roll 6 again are only 1 in 6.
You have good reason to suspect those dice are not fair.
