LessWrong Community Weekend 2025

Join us for the 12th LessWrong Community Weekend (LWCW) in Berlin! This is one of the world's largest rationalist gatherings, bringing together 250+ curious minds from across the globe for four days of deep conversations, learning, and genuine connection.

We're taking over an entire hostel with diverse spaces—both indoor and outdoor—perfect for talking, relaxing, dancing, playing games, learning new things, teaching others, connecting with like-minded people, and simply enjoying life together in our own unique way.
