Scott Alexander's experiment tested how different essays affect people's concerns about AI risk, finding a modest but persistent increase in concern after reading. Longer summary
Scott Alexander conducted an experiment to test the effectiveness of different essays in persuading people about AI risk. Participants were assigned one of five essays to read, including a control essay unrelated to AI. The main outcome was participants' level of concern about AI risk on a 1-10 scale. Results showed that reading the AI-related essays increased concern by an average of 0.5 points, with no significant differences between the four AI essays. The effect persisted at about two-thirds strength after one month. The experiment also looked at secondary outcomes related to specific AI risk questions and analyzed differences based on prior familiarity with the topic. Overall, the study suggests a modest but useful effect from trying to persuade people through essays on this topic. Shorter summary

Scott explores the implications of Sean Carroll's argument against the simulation hypothesis, suggesting that our inability to explain consciousness might indicate we're in a 'ground-level' simulation. Longer summary
Scott Alexander discusses Sean Carroll's argument against the simulation hypothesis, exploring the implications if Carroll's reasoning is correct. He posits that a 'ground-level' universe, incapable of simulating other universes, would have to be strange, potentially banning Turing machines while still allowing for conscious observers. Scott then considers a version of anthropics conditioned on consciousness, suggesting that in a ground-level simulation, consciousness would remain inexplicable to its inhabitants despite their ability to understand all other aspects of their universe. He concludes that if Carroll's deconstruction is correct, our difficulty in explaining consciousness might indicate we're in a ground-level simulation. Shorter summary
