"Rationality is systematized winning" is a slogan that was adopted to patch a bug in human cognition. Namely our endless capacity to delude ourselves about how we did in an attempt to save face. The concept seems to have been absorbed, but I'm skeptical it's translated into more effective action. Certainly it produced many essays on why winning isn't happening. But the fact that we've been publishing essentially the same essay for a decade now implies something fairly fundamental is wrong. This slogan was chosen because it patches the bug, but I fear at the cost of neutering our ability to focus.
I'm reading this, and it seems very reasonable, and then:
So, assume civilization is a set of guidelines that dictate a course of actions. Just like rationality in fact. How can this beat rationality? If it dictates the correct course of actions, rationality will too. And often, rationality can suggest something more effective.
The possible counters c are: (a) rationality is hard work, and mostly sticking with civilization is fine. (b) Or you're not a good enough rationalist (or have enough good information) to beat civilizational guidelines.
But the article does not really suggest those. It says civilization is already winning. Well, it all hinges on the definition of winning. But it's quite clear you can achieve better outcomes through rationality if that's what you care about and are not put off by the extra work (counter (a)).
The counters are interesting but ultimately irrelevant. You can actually rationality arrive at (a): determining that the cost incurred by practicing rationality is more than the benefits accrued. That being said, it's so general a statement, I don't think anyone it can be true for anyone capable to think the thoughts. You can also rationally arrive at (b), and in fact, if it's true you should: civilization IS evidence, and it has to be valued accurately. If civilization guidelines keep trumping your best guesses, the weight of civilizational evidence should increase accordingly.
