This post (especially this section) explores this. There are also some ideas on this website. I've copied and pasted the ideas from that site below. I think it's written with a more international perspective, but likely has some overlap with actions which could be taken by Americans.
For people who haven't clicked through, it might be worth mentioning that this is about insects being used as livestock for other animals.
This matters because you might consider insect farming for human consumption to be more morally ambiguous. (If insects turn out not to be sentient, and insect consumptions displaces consumption of larger, actually-sentient animals, this could be a positive for the world).
However, insects being used as livestock is more clearly negative.
I think this is the same consultation flagged by James here, right? If so, might be worth flagging that.
Glad to see you raising this. I raised a related question here (has a slightly more US-centric angle to it). In that post I do suggest some interventions, but there's not a lot of careful research behind it.
I've upvoted this comment and disagree-voted it. I was initially prone to be dubious of the suggestion. I think lots of us are motivated by important outcomes like children not dying, and linking aid to national self-interest seemed problematic, because children not dying (or other good outcomes) are not the same as national self-interest. Optimising for one is likely to lead to different aid interventions than optimising for the other.
However I've warmed somewhat to the suggestion.
On balance, I still think I disagree with the suggestion, mostly because a hardnosed link to self-interest probably won't be compelling for those who are politically opposed to aid. But I appreciate the prompt to give this some thought.
I think this is definitely an interesting question, and I can see how it has some strategic value for organisations doing scenario planning for the future.
As far as I'm aware (based on conversations with people closer to US government than me) there was an element of "pandemic fatigue" in US government. The government was painfully aware that they had spent a huge amount on COVID already. Proposals to spend even more on an "Apollo programme" or other efforts to ensure we don't have this problem again didn't seem appealing, because some many other priorities had been put on hold and were vying for attention.
I don't remember hearing much about polarisation being an important driver.
Good question, I'm sorry nobody has replied yet. I don't feel like I'm much of an expert on this, so others may be better positioned than me.
My sense is that yes, this may well be impactful, especially if it is clearly communicated. This is a meaningful move, and one that the party will feel -- all parties need financing.
To maximise effectiveness, you likely need to inform the right people. By all means, do tell your MP (assuming your MP is a Labour MP). Saying that you're willing to leave the Labour party makes you less likely to vote for them in future, and they will care about this. In fact, if it's true that it would make you less likely to vote for them in future, do tell them this explicitly, as that's probably what your MP cares about.
Cancelling your Labour membership matters to the people responsible for the finances of the party. I believe those people are probably the Treasurer and General Secretary of the party. I don't know how you would reach out to them, but if there were some way of communicating this to the right people, you could increase your impact.
Good point here:
Another lever to consider, rather than ‘punish government for cutting aid’, is ‘telling the government that effectiveness matters to me when they decide what to cut’. Don’t know how to compare those.
If I'd given more thought to the draft letter, I might have said more on this.
I'm conscious that Jenny Chapman (who is taking over from Anneliese Dodds as Development minister) doesn't seem to have much background in development.
If someone wrote an email which conveyed acceptance of the reality (cuts are going to happen, whether I like it or not), and which suggested that effectiveness matters, this might be viewed as a much more constructive email, which might land better and be more influential.
This is an important and valuable question, thank you for raising it. I'll split my observations into two effects:
Malthusian effects
Other responses have referred to Malthusian effects, by which I mean the concern that with only finite resources, the resources will be spread between more people, and each person will have a worse quality of life.
Benefits of scale
Creating another person doesn't only create another mouth to feed. It also creates another source of ideas and creativity.
For example, each new birth has the potential to become another Norman Borlaug (who is claimed to have saved a billion lives through his research).
Even if 999,999 new people fail to come up with a ground-breaking innovation which makes the world better, if the millionth person does, it could allow everyone to benefit.
Of course, the flipside is that any new person could be the next Hitler/Stalin/insert-your-favourite-bad-guy-here.
Are the Norman Borlaugs winning over the Hitlers?
If you believe the data that seem to suggest that the world has been getting better over recent centuries, the answer seems to be yes.
There's also benefits around the fact that niche interests/needs are better accommodated at scale. If 0.01% of the population has a rare disease, and the population is 10 billion people, that's a million sufferers -- enough scale to incentivise scientific research. And if successful, maybe everyone is cured/treated. For a significantly smaller population that disease may remain untreated for a very long time.
Do the benefits of scale win over the Malthusian effects?
I don't think this is obvious, but I'm inclined to think the benefits of scale win.
If we look at recent examples of challenges that humanity has faced, human ingenuity has managed a few good successes (the aforementioned example of Norman Borlaug and dwarf wheat; the cost effectiveness of solar power has improved dramatically in recent years; smallpox eradication; saving the ozone layer). Don't get me wrong, we still have more to do! But that suggests we want more brains, not less.
Furthermore, decisions we make today should be based on how the benefits of scale will work in the future, not how they were in the past. Will we be better able to use our ingenuity to solve big problems in the future? Some would argue that AI will make us better able to explore creative new solutions (not that everyone will agree on this).
Lastly, and this isn't really answering your question, but rather picking up on a comment of yours. You said that the idea that saving lives makes the world better is a "core assumption of the effective altruism movement". I don't think this is correct. EA is a movement built around using evidence and reason to do good. If the evidence showed that saving lives was bad, the essence of EA would be unchanged. Furthermore, lots of the practice would be unchanged too -- a lot of EA activity is not linked to saving lives.
