Hey Arnold, thanks for the message. Hmm do I understand the question correctly as: if I'm optimising for impact, but wary of burnout, I want to donate as much as possible without lowering my standard of living to an unsustainable level? And you're saying what's personally satisfying might not be the best thing?

That's certainly true. I'm almost sure that I could do more. I suppose I'm just wary of trying to optimise too much, because I think it can be emotionally draining. To be honest I think that social factors can be really important for this though - I would be willing to try to optimise more if those around me were doing it more. But I'm not really sure if that responded to your question!

My intention would be to gradually increase. So in the past I was earning just slightly above the median, but gave 15%. In general I think it's good to have an idea of what income you're comfortable with, and then increase donations significantly as you pass that point. But I set the bar really high here just because I'm aware that my perception of what is enough might change in different life-stages.

To be honest I think my model is super crude and probably not ideal, I would really like to see other models like this!

Hey, totally agree that the sentiment isn't always helpful - it's one that motivates me, but it's definitely not what I say in my elevator pitch to encourage others to donate!

I hope I'm not taking this too seriously, but the examples Bob gave are of looking with concern for the bugs' welfare. Entomologists presumably do that more than your average Instagram user because they actually study and handle the bugs. Others might just look at photos of bugs the same way they look at photos of plants or landscapes. 

I feel a bit confused by this strategy. The normal idea of voting is to express your preference, such that the outcome reflects what the majority prefers. 

If people treat it rather as an opportunity to communicate to others, that seems likely to distort the outcome. In regular political elections I'm ok with that, but in this context where voters are voting altruistically, I'm less sure. 

I'm also confused because the act of writing here is a signal, and probably a clearer one! Could you not have done that and voted for who you genuinely think should be 'elected'?

I agree. Maybe we can just say that veganism focuses on the wrong behavior? In addition to donating, I think voting can be more important than your individual diet. Many animal advocacy or rights organizations seem to recognize this, and refer to animal advocates or animal rights advocates to be more inclusive. They certainly do this for events where they seek to attract a lot of people, like animal rights marches. But for sure, veganism continues to be emphasized too much. 

I also agree that the definition given in the post doesn't reflect popular usage, which is probably something like:

• Vegans avoid causing harm to animals, and so avoid purchasing or consuming animal products. 

This doesn't seem particularly maximizing. The first part reflects the moral commitment, and yes it's possible to be perfectionist about it, but it's not fundamentally. The second part demands evidence of that moral commitment, and it's also far from maximizing, since not consuming animal products is very achievable for most people. So, as long as this definition is interpreted in a reasonable way, it doesn't seem particularly maximalist.

I also have the impression that these fellowships are getting more competitive each year. Do you share that perspective? If so, that would require a further adjustment to the calculation.

As the demotivated person you referenced, I appreciate this! But I think the case for de-motivation is a bit stronger than presented in this calculation, so I'll try to steelman it.

First of all, consider the framing: you've assumed that if I don't get this fellowship I'll continue with the job I already have, and that if I don't apply I'll just have leisure time. In reality many applicants will be looking for a new opportunity, and if they don't get this they'll probably take something else. They might (as I am) be making as many applications as they have energy for, such that the relevant counterfactual is another application, rather than free time.

Here are some more specific points:

• I agree that the base rate is a poor guide to your personal probability. But I would expect that the range of probabilities across applicants is likely to be skewed, such that a number of applicants each have a very significant chance, while the majority of others have next to no chance at all. This would be the case if the hiring team are willing to accept only exceptional candidates, and there are more exceptional candidates than positions, yet the majority of applicants are not exceptional. I expect this skew to be stronger the more applicants there are.
• If you are going to consider the intangible value of the fellowship, then you also need to consider the intangible value of the counterfactual. This will either be that of your current work, or another job you might take (which is hard to estimate, but you could guess at it).
• Similarly to the above, if you're going to consider the information value of applying, then you also ought to consider the information value of applying for whatever else you might have spent the time on (if that's what you would have done). Since many fellowships receive thousands of applications, I presume that most applications get not feedback (as in my own experience). The information value is therefore likely to be higher for opportunities with higher chances of success. Interviews give a greater information value still, so this effect is quite strong. This might even be the main reason why I prefer not to apply for positions where my chance seems so slim.
• A related advantage of focusing on higher-probability positions is that you might be lucky enough to receive multiple offers around the same time. That lets you compare options after learning more about them during the process, and choose the one that seems like the best personal fit. If most of your applications are very low-probability, you’re more likely either to accept the first offer you get, or to pass on a good offer in the hope of a better one later, simply because the relevant information arrives at very different times.
• Lastly, there is a psychological cost to firing out many low-chance applications. Rejections are, after all, demotivating. Getting interviews or offers is highly motivating, even if you end up declining the offers.

This leads to a much much more complicated equation! I asked GPT, to try to link this all together, and well... I'll just link its answer here.

So I remain pretty unsure as to whether it's worth it for myself personally, but I might put in an application anyway :)

Yea, I'm a little surprised (based on the interactions I've had with EAs about the topic). Would be nice if more people commented, to see whether it's real disagreement or just a desire for more rigor. 

Regarding (2), do you think sentience gradually increases, or there's a cutoff? My own memory is of having very intense joy and pain/sadness as a small child, maybe more than now. So while I put less credence in the sentience of young animals, my assumption is that if sentient they could have intense feelings.

I want to push back (3) (larger animals having 'great' lives). I'm not sure if you meant that: but take any pet cat or dog, and then make them hungry, often. Make them cold, make them occasionally very afraid, and give them parasites and untreated injuries. Make them live only 1/4 of their full lifespan. Now even if that's worth living, surely it isn't a 'great' life!
