Scott argues that taking the Giving What We Can Pledge to donate a fixed percentage of income is the single most impactful decision most people can make, eliminating donation stress while maximizing charitable impact. Longer summary

Scott advocates for taking the Giving What We Can Pledge, arguing that committing to donate a fixed percentage of income (typically 10%) to effective charities is one of the most impactful decisions someone can make. He describes how he used to feel stressed and irrational about charitable giving before discovering the pledge, and explains that having a predetermined commitment eliminates the guilt and decision fatigue of responding to individual fundraising appeals. The post emphasizes that for most people, financial donations are their most powerful tool for changing the world, and that making a binding pledge - rather than relying on willpower for each donation - is the key to actually following through on altruistic values.

Scott Alexander argues that military interventions can potentially be a cost-effective way to help foreigners, contrary to a Slate article's claim. Longer summary

Scott Alexander critiques a Slate article arguing that military interventions are an expensive way to help foreigners. He argues that comparing interventions to GiveWell's top charities is flawed reasoning, and presents a cost-effectiveness analysis of the 2011 Libya intervention. Using quality-adjusted life years (QALYs) as a metric, he calculates that the Libya intervention cost about $65 per QALY, which is slightly more cost-effective than donations to the Against Malaria Foundation at $75 per QALY. Scott emphasizes that both figures are extremely low compared to typical healthcare interventions. He concludes that military interventions can potentially be very cost-effective for humanitarian goals, though they come with risks and unpredictable consequences. Shorter summary
