Takes on moral philosophy and the history of this community that I mostly mentioned before but should maybe be put together somewhere:

• Human preferences are very partial/parochial, and this is meta-endorsed. There is a finite number P s.t. for any N>0, the lives of N strangers are less than P times as terminally-valuable for you as the life of your loved one. If you want to be honest with yourself (which you should if it's high-value for you to have accurate beliefs), you should endorse this.
• (Objective, abstract) Morality is fake, both non-cognitivism and error theory have merit. Parochial altruistic preferences (=empathy) are real, rational and superrational cooperation are real. Morality-as-used-in-practice is a process of continuous negotiations about social norms (the "social contract" if you like).
• In particular, utilitarianism is very confused. That said, (super)rational cooperation can cash out as something utilitarianism-ish in some situations. (For example, if it is best for everyone if we precommit to derailing the trolley even if a personal friend is on the other track.)
• Paradoxes such as Pascal's mugging, population ethics and infinite ethics all stem from trying to use a confused framework (impartial and unbounded utility).
• This type of confusion contributed to the failure of Old MIRI's agent foundations programme, by causing it to over-index on ideas like Pascal's mugging and the procrastination paradox.
• The self-deceptive endorsement of impartial unbounded utility obscures the importance of multi-agent considerations in morality-as-used-in-practice, and this contributed to failures of the Effective Altruism movement such as SBF and OpenAI. Ideas such as the "pivotal act" are also sus in a similar way (although I can see versions of that which might be justified).
