Scott Alexander discusses the challenges of community growth, relating his experiences with micronations and rationalist groups to theories about natural group size limits. Longer summary

Scott Alexander reflects on his experiences with micronations and the Bay Area rationalist community, noting that both faced difficulties in growing beyond a certain size. He connects these observations to Samo's research on Dunbar's number and its potential extensions. The post explores the idea of natural group size limits at different scales (e.g., 12, 150, 1000, 90,000 people) and how these might relate to social structures like families, clans, tribes, and city-states. While Scott expresses skepticism about the universality of these exact numbers across different contexts, he acknowledges the apparent difficulty many communities face in growing beyond certain thresholds.

Scott Alexander explores the concept of the 'hive switch' in nerds, realizing that they can experience group unity when they find the right in-group. Longer summary

Scott Alexander reflects on Jonathan Haidt's concept of humans being '90% chimp and 10% bee', initially thinking he lacked the 'hive switch' that allows people to unite into a superorganism.

However, he realizes that nerds can experience this 'hive switch' when they find the right in-group, citing his experiences with micronations and the rationalist community. He concludes that the ability to connect deeply with an in-group is valuable and advises those who think they lack this ability to find an in-group that truly resonates with them. Shorter summary
