The Center for Applied Rationality's in-practice corporate culture, by virtue of literally every person in the building being an explicit rationalist, has an even more powerful and valuable property - people know they won't be punished for changing their minds or admitting they were wrong. Plus you can say "Value of information!" to justify trying-at-least-once something that most people think won't work, since nobody's going to stick to it due to the sunk cost fallacy afterward.
Despite everything I knew in theory about the virtue of being able to change one's mind, including having written a major blog post Sequence about it, my ability to do so in practice took a substantial leap after the Center for Applied Rationality came together, I spent a lot of time coworking with some of the people, and my monkey brain got to see that other people actually were implementing that thing I'd written about where people were allowed to change their minds, and they were getting high-fives and not being punished for it.
