I generally view human decisions as a result of evolutionary pressure. We've been molded by our brain development to make things good enough to survive short-term (to next year). We're very good at planning for winter. We might even react intelligently to a terroristic or rogue state use of atomic weapons. We've also been molded to plan enough to get our progeny to breeding age. We can enact 10-20yr plans with some skill. Beyond that range... we have never had evolutionary pressure to think and act on those ranges. "Climate Change will kill our grandkids!" isn't really sufficiently pressuring to us. The Great Filter of the Fermi Paradox fame may just be: species can easily get to the Atomic Age without adequately planning how to prevent ruining themselves with resource depletion and environmental slow poisoning.
