Rationality is sort of the ur-procedure, but after a certain point - the point where you're no longer buying into supernaturalist superstition, begging for a Darwin Award, or falling for cheap scams

...or failing to put water bottles on your roof, or failing to sign up for cryonics...

its marginal practical value diminishes.

If your cost of obtaining further rationality is very high, so that it's going at a slow rate, then I suppose that's possible. But I think we have different views on the extent to which "people are crazy, the world is mad" holds ubiquitously true of ordinary human existence and offers low-hanging fruits.
