The origin of Petrov Day, as an idea for an actual holiday, is this post by Eliezer Yudkowsky. Arkhipov got a shout-out in the comments almost immediately, but “Petrov Day” was the post title, and it’s one syllable shorter.
There are many other things like Petrov Day, in this and every culture — arbitrary decisions that became tradition.
But of course, “started for no good reason” doesn’t have to mean “continued for no good reason”. Norms that survive tend to survive because people find them valuable. And there are plenty of things that used to be EA/rationalist norms that are now much less influential than they were, or even mostly forgotten. The first examples that come to mind for me:
Early EA groups sometimes did “live below the line” events where participants would try to live on a dollar a day (or some other small amount) for a time. This didn’t last long, because there were a bunch of problems with the idea and its implementation, and the whole thing faded out of EA pretty quickly (though it still exists elsewhere).
The Giving What We Can pledge used to be a central focus of student EA groups; it was thought to be really important and valuable to get your members to sign up. Over time, people realized this led students to feel pressure to make a lifelong decision too early on, some of whom regretted the decision later. The pledge gradually attained an (IMO) healthier status — a cool part of EA that lots of people are happy to take part in, but not an “EA default” that people implicitly expect you to do.
