I think "Overton window" is a pretty load-bearing concept for many LW users and AI people — it's their main model of policy change. Unfortunately there's lots of other models of policy change. I don't think "Overton window" is particularly helpful or likely-to-cause-you-to-notice-relevant-stuff-and-make-accurate-predictions. (And separately people around here sometimes incorrectly use "expand the Overton window" to just mean with "advance AI safety ideas in government.") I don't have time to write this up; maybe someone else should (or maybe there already exists a good intro to the study of why some policies happen and persist while others don't[1]).
Some terms: policy windows (and "multiple streams"), punctuated equilibrium, policy entrepreneurs, path dependence and feedback (yes this is a real concept in political science, e.g. policies that cause interest groups to depend on them are less likely to be reversed), gradual institutional change, framing/narrative/agenda-setting.
I liked the book Policy Paradox in college. (Example claim: perceived policy problems are strategically constructed through political processes; how issues are framed—e.g. individual vs collective responsibility—determines which solutions seem appropriate.) I asked Claude for suggestions on a shorter intro and I didn't find the suggestions helpful.
I guess I think if you work on government stuff and you [don't have poli sci background / aren't familiar with concepts like "multiple streams"] you should read Policy Paradox (although the book isn't about that particular concept).
I've registered that you think this but don't currently really have any idea what mistakes you think people make when they think in terms of Overton Window that would go better if they used these other concepts.
"expand the Overton window" to just mean with "advance AI safety ideas in government.
You're right that it's not the only useful model or lever. I don't think you're right that it shouldn't be a large focus for long-term large-scale changes. The shift from inconceivable to inevitable takes a lot of time and gradual changes in underlying beliefs, and the overton window is a pretty useful model for societal-expectation shifts.
