Join the 13th LessWrong Community Weekend (LWCW) in Berlin - one of the world’s largest rationalist social gathering which brings together 250+ aspiring rationalists from across Europe and beyond for 4 days of intellectual exploration, socialising and fun.

We will be taking over the whole hostel with a huge variety of spaces inside and outside to talk, relax, dance, play, learn, teach, connect, cuddle, practice, share... simply enjoy time together our way.

The whole event will be participant-driven in an unconference style: shortly before, and any time during, the weekend, a digital event schedule is filled with 100+ workshops, talks and activities by the attendees.

LWCW is family & LGBTQIA+ friendly. After past years' amazing experiences we are increasing our effort into creating a diverse event where people of all ages, genders, backgrounds and experiences feel at home. Three things bring us together:
1. The curiosity for new perspectives to gain a truthful understanding of the universe and its inhabitants.
2. A passion for developing practices that achieve our personal goals, and as such, those of humanity at large.
3. Caring for empathetic relationships that support and inspire us on our journey.

This event has a special place in our hearts and we truly think there’s nothing else quite like it. It’s where so many of us made friends with whom we have more in common than each of us would’ve thought to be possible. It’s where new ideas have altered our opinions or even changed the course of our life - in the best possible way.
