Participatory longtermism
Values and reflective processes, Effective Altruism
Most longtermist and EA ideas come from a small group of people with similar backgrounds, but could affect the global population now and in the future. This creates the risk of longtermist decisionmakers not being aligned with that wider population. Participatory methods aim to involve people decisionmaking about issues that affect them, and they have become common in fields such as international development, global health, and humanitarian aid. Although a lot could be learned from existing participatory methods, they would need to be adapted to issues of concern to EAs and longtermists. The fund could support the development of new participatory methods that fit with EA and longtermist concerns, and could fund the running of participatory processes on key issues.
Additional notes:
There is a field called participatory futures, however it seems not very rigorous [based on a very rough impression, however see comment below about this], and as far as I know hasn’t been applied to EA issues.
Participedia has writeups of participatory methods and case studies from a variety of fields.
SEP for every subject
Epistemic institutions
Create free online encyclopedias for every academic subject (or those most relevant to longtermism) written by experts and regularly updated. Despite the Stanford Encyclopedia of Philosophy being widely-known and well-loved there are few examples from other subjects. Often academic encyclopedias are both behind institutional paywalls and not accessible on sci-hub (e.g. https://oxfordre.com/). This would provide decisionmakers and the public with better access to academic views on a variety of topics.
