What would your AI red lines be? Decide now what would make you act on AI, and what you'd do. Then share it. + Another line Your name (optional) What you do (optional) Share without my name You've changed your red lines since you shared them. Share your red lines Sharing gives you a link and an image to post. Your red lines go on this page's public wall once you copy your link or post them. No account needed.

You may also get one when something happens that may cross one of them. Your address is kept only for this and never shown, and every email has a link to stop.

Skip for now Where the evidence comes from From a 2016 review of 138 trials with 19,951 people (Harkin and others, Psychological Bulletin ). In each trial, some people were prompted to keep track of a goal and others weren't. On average, the people who were prompted did better at reaching it. Keeping track helped more when other people could see it (0.55) or when it was reported to someone (0.47) than when it stayed private (0.19). It helped more when people kept a written record (0.43) than when they didn't (0.29). The numbers are effect sizes: bigger means it helped more. Nearly all the trials were about health goals, like weight or blood pressure. Nobody has tested red lines for AI, so read this as a guide, not a promise.

In 1944 he went to Los Alamos with the British team on the Manhattan Project. He had one reason for being there: the fear that Nazi Germany would build an atomic bomb first. By the end of 1944 it was clear Germany would not. The reason he had come no longer held, so he resigned and went back to Liverpool. He is the only scientist known to have left the project on grounds of conscience. Most of us never write down why we're somewhere. When things change slowly, nothing tells us to stop. Rotblat had that moment because he knew his reason. This page started as The Rotblat Line, to help you write down yours: the specific things that would make you act, and what you'd do, whether that's quitting, speaking up or finally getting involved. He was born on 4 November, so that's the day it suggests re-reading your red lines each year. 1908 Born in Warsaw on 4 November 1944 Joins Los Alamos, and leaves before the year is out 1957 Co-founds the Pugwash Conferences 1995 Shares the Nobel Peace Prize with Pugwash 2005 Dies in London, aged 96 Write your red lines
