>when it is [relatively] cheap to believe something (even when it is wrong) it is rational to believe it.
"Engineering" is the most intuitive for humans to check for rational beliefs.
"Science" is a method of eliminating human bias beforehand as much as possible as to maximize the space of possibilities in terms of technology ("knowledge").
"Anarchy" in the realm of social order in its most basic form minimizes the abuse of power of the few by optimizing structures of hierarchical order.
Every single one of this human enterprises is non-telic, a constant work in progress. My sense is that through its accelerated atomized structure and loss of power "the West" has lost itself in delusions and constant anxiety resulting in disproportionate numbers of megalomaniac leaders without account and apathetic citizens without agency.
Everyone wants to live in "interesting times" but no one wants to live through it with one lifeline and a 50% chance of belonging to the bottom 1% in terms of credits points (wealth). I surely wouldn't play that game, so what do I care what my rational beliefs are (no participation) as long as every belief I fancy has an underlying cynicism it is a far effective strategy to avoid being scammed which could potentially cost the lifeline.
Have you looked at the biases of the many recently?
