What is Community Notes and how does it work?
the work that you guys do has had such a tremendous impact on the way the world works i want to start with just giving people a brief understanding
of what is community notes someone on x can see a post if they think it's misleading they can propose a note that they think other people might find informative other people can then
rate that note we actually look for agreement from people who have disagreed in the past and and what we see is when people actually have that sort of surprising agreement That's what makes the notes so neutral and accurate and well-written, really, overall.
There's many people that are very polarized. How do you deal with people that are like super anti-vax, super Jan 6?
One philosophical thing that's important is that we want all of humanity to participate. And sometimes people are surprised by that. We have all of humanity. We then have the data to understand what notes will be helpful to actual humanity. Every post is eligible for notes. We shouldn't exempt Elon. We shouldn't exempt government figures. We should be like everyone. Even advertisers can get notes.
There have been external studies run by people totally independent of us who have found that if you take a post with or without a community note, that actually people's agreement with the court claims in the post does change if they see it with the note versus without.
Is there anything else along the lines of just working for Elon within an org Elon runs that might surprise people?
If I were to start a company in a company, it would be even leaner than I would have made it before. I've been amazed with just how much the team is able to accomplish with a small group, and I think because of a small group.
Today, my guests are Keith Coleman, product lead for Community Notes, and Jay Baxter, founding ML engineer and researcher for Community Notes. This conversation may be my newest favorite podcast episode so far. Community Notes is one of the most impactful and clever and also underappreciated products in the world right now. If you ever use x slash twitter and you see a note underneath a tweet correcting the misinformation in that tweet, that is community notes. I've never heard a deep dive into the story behind the product and the team that built it, and I'm excited to bring you just that. We get into the surprising origin story of the product, how the algorithm actually works, how the algorithm emerged out of an internal contest within Twitter, the principles behind community notes and why staying true to them has been so key to its success, also how it survived four different leaders including Elon and Jack, and why it's now a big part of the solution to solving misinformation on the internet, including recently being adopted by Meta as their main fact-checking tool.
