One important stroke of luck is to believe that it's
not luck.
I've been gestating an essay about "useful lies" for a while now. Some things that we know aren't truly true are embraced as if they are true because of the utility of doing so.
So for example, believing that success is not related to luck. It's untrue, in my estimation. But if you truly accept it you wind up with silly notions like Insha'Allah and nothing much gets achieved.
Or take realism/legalism in law. Sure, judges are biased, judges affect policy yadda yadda. But actually embracing that reality makes the legal system work less well. Meanwhile, "strict and complete legalism" is a bit of a nonsense, but judges who embrace it have higher utility because their judgements are more likely to be respected and accepted.
The reason I haven't written it is because I've kinda written it already[1] and I can't think of a better way to explain what I'm trying to convey.
I'm also deeply uncomfortable with being caught between the essential unknowability of complex systems and wanting all events and system configurations to be explicable. Reading Hayek after Dekker has been a very unhappy experience for me.
