At its heart, EA seems to naturally tend to promote a few things:
- a larger moral circle is better than a smaller one
- considered reasoning ("rationality") is better than doing things for other reasons alone
- efficiency in generating outcomes is better than being less efficient, even if it means less appealing at an emotional level
I don't know that any of this are what EA should promote, and I'm not sure there's anyone who can unilaterally make the decision of what is normative for EA, so instead I offer these as the norms I think EA is currently promoting in fact, regardless of what anyone thinks EA should be promoting.
I think a healthy dose of moral uncertainty (and normative uncertainty in general) is really important to have, because it seems pretty easy for any ethical/social movement to become fanatical or to incur a radical element, and end up doing damage to itself, its members, or society at large. ("The road to hell is paved with good intentions" and all that.)
A large part of what I found attractive about EA is that its leaders emphasize normative uncertainty so much in their writings (starting with Nick Bostrom back in 2009), but perhaps it's not "proselytized" as much as it should be day-to-day.
