Is anyone aware of previous writings by EAs on founding think tanks as a way of having an impact over the long-term?
In the UK, I think the Fabian Society and the Centre for Policy Studies are continuing to influence British politics long after the deaths of their founders.
Slate Star Codex had an interesting review on the Fabian Society and how advocacy can backfire.
Open Philanthropy Project has an interesting review of the Center for Global Development.
Is anyone aware of any research / blog posts specifically on how much free range hens suffer? Most of the ones I can see repeatedly deviate from this question.
