LessOnline
31 May - 2 June, 2024
Lighthaven Campus, Berkeley, CA
The goal is to bring together a "mostly-online subculture of people trying to work together to figure out how to distinguish truth from falsehood using insights from probability theory, cognitive science, and AI." [1]
The weekend will be filled with talks, workshops, puzzle-hunts, dance parties, and late-night conversations around the fireside. If you have a session or activity you might like to run at LessOnline, let us know!
Lighthaven felt rambly and wondrous and fun without being pretentious? Felt like an incredibly-well-executed, 11-of-10 house party venue (laudatory) crossed with Disneyland.

Manifest 2024
Manifest (Fri Jun 7 - Sun Jun 9) is a festival for forecasting and prediction markets, hosted by Manifold and Manifund.
It's happening one week after LessOnline, both at Lighthaven.
So we're teaming up with Manifest to offer a discounted ticket to both events, as well as a weeklong Summer Camp in between the two.
If you'd like to pay for your Manifest ticket in mana, Manifold is offering various discounts; see their ticketing site for more details.
