Welcome to The Nonlinear Library, where we use Text-to-Speech software to convert the best writing from the Rationalist and EA communities into audio. This is: Examples of someone admitting an error or changing a key conclusion, published by Lizka on June 27, 2022 on The Effective Altruism Forum. I think that changing our minds and owning up to past mistakes are two of the key virtues of effective altruism. I’d love to acknowledge instances of this and try to collect such stories as examples to follow. Here are some examples to start with: Hauke Hillebrandt: [updated] Global development interventions are generally more effective than climate change interventions David Manheim: A Personal (Interim) COVID-19 Postmortem Holden Karnofsky: Three Key Issues I've Changed My Mind About Many organizations in effective altruism have pages about their past mistakes Andrew Gelman: I was looking through the wrong end of the telescope (this one isn’t about EA) Do you know of others? Please feel free to share examples of yourself doing this. I think the best examples would have the following properties: An important error or mind-change A public change of conclusion or explanation of the error In a context or conversation that’s relevant to effective altruism Also relevant: How we can make it easier to change your mind about cause areas Epistemic Legibility - EA Forum Six Ways To Get Along With People Who Are Totally Wrong If you don't have good evidence one thing is better than another, don't pretend you do Discussion norms (topic page on the Forum) P.S. This is partially prompted by the Criticisms Contest. I’d be excited to see people engage with criticisms or red teaming of their work — especially when this leads to real changes of position or conclusion. Thanks for listening.
