Charitable Giving
In 2010, as a graduate student, I took the🔸10% Pledge (to give 10% of my income to the most effective charities I can find), and haven't regretted it for a moment. It's very easy to acclimatize to a 10% change in income, especially if you start early in your career — no radical lifestyle changes are required — and in return you get to achieve an incredible amount of good, helping those who need it most.
Brainstorm how you could do the most good for the least effort or sacrifice on your part. I suspect that the 10% pledge would top the (ratio-ordered) list for many people. But whatever turns out to be the most efficient use of your moral efforts, I encourage you to do that first.
If you're curious about where best to donate, GiveWell's Top Charities are a safe bet for the risk-averse. But if you're willing to balance higher uncertainty for higher potential reward, I know of no better options than the EA Funds.
Finally, I encourage you to give publicly! People are more likely to give to charity when they see that others around them are doing so. I've been excited to see Giving What We Can grow to over 10,000 pledgers. Maybe you'll be next?
