Doing something to democratize randomized controlled trials (RCTs) - thereby reducing the risk involved in testing new ideas and interventions.
RCTs are a popular methodology in medicine and the social sciences. They create a safety net for the scientists (and consumers) to test that the drug works as intended and doesn't turn people into mutants.
I think using this methodology in other fields would be a high-leverage intervention. For example startups, policy-making, education, etc. Being able to try out new ideas without facing a huge downside should be a feature of every field. Big institutions already conduct similar tests before they release something. But I'm wondering how useful it would be to allow small institutions, startups, and maybe even individuals to do this.
Plus, adding an RCT into the launch pipeline of any intervention/product allows us to see the unintended consequences before they're out there. I think this would have at least been helpful for the social media companies.
Based on some googling, I've understood that RCTs are very costly. But if the reasoning makes sense, this is exactly the kind of thing others can't try out that a megaproject should.
Here's a paraphrased quote by Eliezer Yudkowsky, that is relevant in this context: If people could learn from their mistakes without dying from them, well actually, that in itself would tend to fix a whole lot of problems over time. [source]
P.S. I'm thinking on working on this idea full-time in 2022. It would be very helpful to hear whatever criticism/thoughts you have - It'll help me make sure my time is effectively spent.
On the last point, during the early Pliocene, early hominids with much worse technology than us lived in a world in which temperatures were 4.5C warmer than pre-industrial. It would be a surprise to me if this level of warming would kill off everyone, including people in temperate regions. There's more to come from me on this topic, but I will leave it at that for now
