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 was my thought too, delayed gratification. Lot’s of people make short term decisions that have negative long-term effects on their mental, physical, or financial health. And humanity does it as well, such as pollution or using fossil fuels when we know it’s going to cause problems in the future.
