>There are some thoughtful subs (star something codex) but overall it has a culture of people who write well but their reasoning stinks. They have strong opinions and make assertions speculatively.

This has been my experience of the "rationalist sphere" (specifically downstream of reddit and Substack) that pride themselves on supposedly charitable longform discussion.

They, as a community, identify as utilitarian Bayesian rationalists, but really optimize only for metacontrarian sophistry--"reactive logorrhea" in one member's own words.

It's like watching Sports Center for the Extremely Online--great for keeping abreast of what the heated controversies are, but absolutely terrible for actually shedding light on them.
