Background: I've been donating since 2018, but I only signed the giving pledge last week. Thanks to @Amalie Farestvedt 🔸 from GWWC, Anthony Wong and others for helping me with the decision.

My reasons for donating

1. Like most EAs, I want to do good, and recognize that my money can go a hell of a way to helping other people, animals, or preventing bad things from happening. I'm so grateful that there are incredibly impactful opportunities out there.
2. But, less commonly in EA, I also think... that I shouldn't have as much money as I do. I think the world is built on inequalities - and sure, the division of labour is powerful, bringing me the laptop that I'm writing on, but I think a lot of what I have is also only possible due to the exploitation of other people and animals. For the record, I don't come from old money. I just grew up in a privileged enough environment to go to a good school, have a supporting family and one that could push me in the right directions. But these things were already only possible because of advantages that depended on historical injustices. In this sense, I don't think I'm just lucky to have what I have, I also think it's not rightfully mine, and I ought to try to correct those injustices by giving.

Where I donate

Most recently I've donated to:

1. Wild Animal Initiative. I think that wild animal suffering is by far the biggest source of suffering in the world today, it is incredibly neglected, and the main challenge for tractability is getting the ball rolling - which is exactly what WAI are doing.
2. Effektiv Spenden's AI safety fund. I wish there were a GiveWell for AI safety. I find it very hard to judge for myself which AI safety orgs are the most effective, so I simply choose to defer to others for this one.

My income-dynamic pledge

Just last week I took the trial pledge, to give 1% of my income for 5 years, and to give 10% after that.
But I also pledged the following:

To

- always give at least 1% of my expenditure. 

- give 10% of my net income once I earn the median income in my city

- give 60% of my net income once I earn double the median income in my city

This is, in essence, a dynamic pledge. Here are my reasons for this set up:

1. I think donating 10% of your income can actually be hard if your income is low. If, with a given standard and cost of living, you are only able to save 10% of what you earn, then 10% donations might prevent you from saving. But I think saving is important for personal security, which is in turn important to allow you to be flexible in terms of changing location or career. Having a low salary can even be a desirable thing, e.g. if you want to spend a significant amount of time doing high-impact volunteering.
2. Despite the above, I think it's good to keep the habit of donating even if you can't donate much at all (and even if you don't have a meaningful income).
3. The further pledge reflects better how I think it is morally correct to donate - i.e. to set a ceiling above which you donate all additional money that you earn. This allows people to be comfortable/live well, but says that you don't need more than that, and would do better to donate it. The only problem is... what is 'enough' isn't totally clear, and your perception of it might change over time. Also, if you reach that threshold, you might lose any incentive to work for a pay rise, thereby donating less than the counterfactual. Lastly, I think that our perception of what's enough is highly dependant both on the cost of living and the relative wealth of those around us (it feels bad to be comparatively poor, even if you live in a wealthy place). For that reason I based the thresholds on the median income of the city.
4. The 10% pledge is normally defined as 10% of gross income (i.e. before tax). Net income (after tax) seems far preferable to me - I have no control over that money that I give up to tax, and tax rates vary greatly between countries and states. In a high-tax area 10% of your income could be quite a lot.
5. I fear regret, so I made a pledge which I consider quite conservative. I expect to donate more than I've pledged, but I feel confident that I will do at least this and won't come to regret it. I'm also confident that when the trial period runs out, my income will be high enough that I'll be giving 10% anyway.

In short: I think that dynamic pledges are both less demanding for the pledger at a low income, and more morally correct at high incomes. I would be excited if GWWC made an official option for a pledge of this form, and would like to hear if other people have made similar kinds of pledges.
