Scott Alexander compares two contrasting models of how social movements gain or lose respectability, using examples from gay rights and environmental issues to explore their implications. Longer summary

Scott Alexander explores the concept of 'respectability cascades' in social movements, comparing two contrasting models. The first model, exemplified by the gay rights movement, suggests that when less respectable individuals publicly support a cause, it gradually becomes more acceptable for increasingly respectable people to join. The second model, illustrated by issues like endocrine disruptors and immigration, suggests that when disreputable people champion a cause, it becomes toxic and respectable people avoid it. Scott discusses the strategic implications of these models, particularly for his own interest in protecting scientific integrity from regressive leftism. He considers various factors that might determine which model applies in a given situation, such as the initial level of taboo, the likeability of supporters, and the availability of alternatives for supporters.

Scott Alexander argues that the Intellectual Dark Web can be both popular and silenced, explaining various mechanisms of social censorship and how they apply to controversial thinkers. Longer summary

Scott Alexander argues that the 'Intellectual Dark Web' (IDW) can be both popular and silenced, contrary to criticisms. He points out that marginalized groups often have famous spokespeople, taboo ideas tend to generate celebrity, and fame doesn't protect ordinary supporters from social repercussions. He explains how the internet has enabled controversial voices to be heard, and suggests that the IDW's complaints about threats and harassment should be taken seriously. Scott also argues that the IDW likely still self-censors to some degree, and that silencing is more about preventing common knowledge than suppressing support or leaders. Shorter summary
