I like this broad framing of epistemics and interventions to improve it! I've spent some cognitive compute on what could constitute an introductory curriculum on epistemics in certain social circles I'm part of. I concluded that I'd probably start with even more basic ideas: teaching robust reasoning and basing beliefs on evidence; sometimes just clearly formulating beliefs.
I have found competitive debating to be relatively effective in improving technical proficiency in reasoning, but I've also seen such skill growth deepen confirmation bias by providing more tool to justify pre-existing beliefs. This probably implies the importance of pairing more "technique-focused" practices with things that improve epistemic virtuosness (therapy / ego reduction?).
Some ideas / sectors for impactful businesses:
Concerns:
On a side note, I think it’s useful to design an impact-focused business in a way that makes “value drift” less likely, e.g., by incorporating as a benefit corporation, having a stakeholder representation on a Board and/or an ethics committee, explicitly tracking impact, and nurturing positive corporate culture. I also speculate that worker cooperative model reduces propensity to engage in rent-seeking, but don’t have good evidence for that.
