We're evolutionarily hard wired for basinism. Every other animal on the planet that can't form good explanations is a basian. And so we need general relativity to correct the errors in newton's theory of gravity, even though general relativity is our best theory right now. There can be no final theory of gravity. All we have is better and better approximations to reality. I think the reason we fall into basins so easily is probably related to why we fall into pessimism so easily.
