Donating more and better is the best strategy to maximise impact for the vast majority of people working in impact-focussed organisations?

If you believe donating to the most cost-effective organisation (at the margin) is over 100 times as cost-effective as donating to the one you work for, and that you are 10 % more cost-effective than the 2nd best candidate for your job, you can have more impact through donations than through work donating 0.1 % (= 1/100/10) more of your gross income to the most cost-effective organisation, and more than 10 (= 1/0.1) times as much impact through donations as through work donating 10 %. In this case, increasing your donations to the most cost-effectiveness organisation by x % would be 10 times as impactful as increasing the cost-effectiveness of your work by x %, which suggests focussing on donating more and better.

I think the most cost-effective organisation is over 100 times as cost-effective as the vast majority of impact-focussed organisations. My top candidates for the most cost-effective organisation are, ordered alphabetically, the Arthropoda Foundation, Shrimp Welfare Project (SWP), and Wild Animal Initiative (WAI). I believe any of these is:

So I conclude increasing the impact of donations via donating more and better is the best strategy to maximise impact for the vast majority of people working in impact-focussed organisations.

You may disagree with my estimates which suggest prioritising animal welfare. However, I would say increasing the impact of donations is also the best strategy to maximise impact for (random) people working in the area they consider most cost-effective. Benjamin Todd thinks â€śit’s defensible to say that the best of all interventions in an area are about 10 times more effective than [as effective as] the mean, and perhaps as much as 100 times”, which is in agreement with the cost-effectiveness of interventions following a heavy-tailed distribution. If so, jobs were uniformly distributed across interventions, and a person in a random job within an area were 10 % more cost-effective than the 2nd best candidate for their job, them donating 10 % more of their gross salary to the best interventions in the area could have 10 to 100 times as much impact through donations as through work. In reality, I assume there are more jobs in less cost-effective interventions, as the best interventions only account for a small fraction of the overall funding. Based on Ben’s numbers, if there are 10 times as many people in jobs as cost-effective as a random one as in the most-effective jobs, a person in a random job within an area who is 10 % more cost-effective than the 2nd best candidate for their job, and donates 10 % more of their gross salary to the best interventions in the area is 100 (= 10*10) to 1.00 k (= 100*10) times as impactful as a person in the same job not donating.

I think you are conflating your specific cause prioritisation and a general question of how people who care about impact should think. If someone held your course prioritisation then they should clearly work at one of those top organisations, otherwise help with the issues, or earn the highest salary they can and donate that. I.E earning to give. Working at other impact-focused organisations not focused on those top causes wouldn't make sense. I think that generally you should optimise for one thing rather than half-hardly optimising for several.

However, many people do not share your cause participation which leads to quite different conclusions. I have no regrets about doing direct work myself

So you think ppl doing direct work should quit and earn to give if they could thereby double their salary? Can't be the right recommendation for everyone!

Hi Tom,

It depends on the organisations which would receive the additional donations. If the person quitting their job is 10 % more cost-effective than the person who would replace them, donates 10 % of their gross annual salary to an organisation 10 times as cost-effective as their initial organisation, their donations doubled as a result of quitting, and there was no impact from direct work in the new organisation, their annual impact after quitting would become 1.82 (= (0 + 0.1*2*10)/(0.1*1 + 0.1*10)) times as large as their initial annual impact.

I think this question would have been b more effectively asked without going through your animal welfare argument for the upteenth time.

 If you're really asking a genuine and important question about the value of direct work vs donating, why not just keep the first paragraph which states your argument well enough, without your second paragraph (which contains most of the words in the question), which is a distraction from your main point which can easily alternate people like me and drag the discussion away from the question itself.
