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?
This one so much. How can people not realize if everyone stood back in a larger halo around the carousel, it would be so easy for everyone to get their bag when it’s up. I usually stand back at a distance, and if people have it completely blocked standing right next to it I grab right around them getting uncomfortably in their personal space.
