Our ancestors survived through a bias for action (e.g. eating every scrap of food I can get my hands on or clubbing a creature that looks at me sideways) not a bias for planning (thinking about retirement from hunting and gathering).
We eagerly romp with him through the follies of confirmation bias (our tendency to reaffirm our beliefs rather than contradict them), narrative fallacy (our weakness for compelling stories), silent evidence (our failure to account for what we don't see), ludic fallacy (our willingness to oversimplify and take games or models too seriously), and epistemic arrogance (our habit of overestimating our knowledge and underestimating our ignorance).
