Manifest 2024 is a festival that we organized last weekend in Berkeley. By most accounts, it was a great success. On our feedback form, the average response to “would you recommend to a friend” was a 9.0/10. Reviewers said nice things like “one of the best weekends of my life” and “dinners and meetings and conversations with people building local cultures so achingly beautiful they feel almost like dreams” and “I’ve always found tribalism mysterious, but perhaps that was just because I hadn’t yet found my tribe.”

However, a recent post on The Guardian and review on the EA Forum highlight an uncomfortable fact: we invited a handful of controversial speakers to Manifest, whom these authors call out as “racist”. Why did we invite these folks?
First: our sessions and guests were mostly not controversial — despite what you may have heard
Here’s the schedule for Manifest on Saturday:
(The largest & most prominent talks are on the left. Full schedule here.)
And here’s the full list of the 57 speakers we featured on our website: Nate Silver, Luana Lopes Lara, Robin Hanson, Scott Alexander, Niraek Jain-sharma, Byrne Hobart, Aella, Dwarkesh Patel, Patrick McKenzie, Chris Best, Ben Mann, Eliezer Yudkowsky, Cate Hall, Paul Gu, John Phillips, Allison Duettmann, Dan Schwarz, Alex Gajewski, Katja Grace, Kelsey Piper, Steve Hsu, Agnes Callard, Joe Carlsmith, Daniel Reeves, Misha Glouberman, Ajeya Cotra, Clara Collier, Samo Burja, Stephen Grugett, James Grugett, Javier Prieto, Simone Collins, Malcolm Collins, Jay Baxter, Tracing Woodgrains, Razib Khan, Max Tabarrok, Brian Chau, Gene Smith, Gavriel Kleinwaks, Niko McCarty, Xander Balwit, Jeremiah Johnson, Ozzie Gooen, Danny Halawi, Regan Arntz-Gray, Sarah Constantin, Frank Lantz, Will Jarvis, Stuart Buck, Jonathan Anomaly, Evan Miyazono, Rob Miles, Richard Hanania, Nate Soares, Holly Elmore, Josh Morrison.
Judge for yourself; I hope this gives a flavor of what Manifest was actually like. Our sessions and guests spanned a wide range of topics: prediction markets and forecasting, of course; but also finance, technology, philosophy, AI, video games, politics, journalism and more. We deliberately invited a wide range of speakers with expertise outside of prediction markets; one of the goals of Manifest is to increase adoption of prediction markets via cross-pollination.
Okay, but there sure seemed to be a lot of controversial ones…
I was the one who invited the majority (~40/60) of Manifest’s special guests; if you want to get mad at someone, get mad at me, not Rachel or Saul or Lighthaven; certainly not the other guests and attendees of Manifest.
My criteria for inviting a speaker or special guest was roughly, “this person is notable, has something interesting to share, would enjoy Manifest, and many of our attendees would enjoy hearing from them”. Specifically:
- Richard Hanania — I appreciate Hanania’s support of prediction markets, including partnering with Manifold to run a forecasting competition on serious geopolitical topics and writing to the CFTC in defense of Kalshi. (In response to backlash last year, I wrote a post on my decision to invite Hanania, specifically)
- Simone and Malcolm Collins — I’ve enjoyed their Pragmatist’s Guide series, which goes deep into topics like dating, governance, and religion. I think the world would be better with more kids in it, and thus support pronatalism. I also find the two of them to be incredibly energetic and engaging speakers IRL.
- Jonathan Anomaly — I attended a talk Dr. Anomaly gave about the state-of-the-art on polygenic embryonic screening. I was very impressed that something long-considered science fiction might be close to viable, and thought that other folks would also enjoy learning about this topic.
- Brian Chau — I’ve followed Brian’s Substack since before he started Alliance for the Future. I’m quite uncertain whether AI Pause or e/acc is the right path forward for AI, and know folks on both sides. To get more clarity on the issue, I was specifically interested in setting up a debate between Brian and Holly Elmore, who runs PauseAI US (an organization which Manifund fiscally sponsors).
- Stephen Hsu and Razib Khan were invited by my cofounder at Manifold, Stephen Grugett; I’m less familiar with their work, but have enjoyed our interactions to date.
I obviously do not endorse all viewpoints held by all of our invited guests. For example, I find some things that Hanania has written on Twitter to be quite distasteful, and would not have asked him to come if Twitter!Hanania was the only point of reference I had. But my read of his Substack, as well as our professional interactions, led me to believe that there was more to him than simply being a provocateur.
In general, I think it’s much more important that a particular speaker has something to add, than that they have no skeletons in their closet. I stand behind every one of the speakers we asked to come; they have taught me much, and I am grateful they chose to attend our event. For more on this philosophy, see Scott Alexander on “Rule thinkers in, not out” or Tracing Woodgrains on engaging with your opponents.
Bringing people together with prediction markets
It’s not entirely an accident that a prediction market festival would draw in disagreeable folks. A functioning prediction market requires people with opposite views on an issue to get together and agree to place a bet. Many prediction markets, such as PredictIt and Polymarket, feature more right-wing than left-wing participants. While I consider myself approximately libertarian/liberal, I think such right-leaning presence is great; better than the siloed echo chambers that other online platforms produce.
One of my hopes with the Manifest event was to bring together people with opposing views on issues. Online discourse is very polarizing nowadays; I enjoy hosting in person events because meeting in meatspace reminds everyone that their ideological opponents are also human. The AI Pause vs Accelerate debate between Holly Elmore and Brian Chau is one organized example of this; I expect there were many more chances for ideological conflict over the course of the weekend.
We do take attendee safety seriously, and retained two different community contacts and full-time security guards at the front entrance. We also had a short list of do-not-admits: folks who would not have been permitted access to Manifest because of past infractions in the rationality and EA communities. If any attendees were made to feel unsafe, we would have expelled the offenders from our event.
Anyways, controversy bad
At one point a couple months before the event, Rachel, Saul and I discussed the concern that we’d invited too many controversial folks to Manifest. Contrary to what you might believe at this point, I don’t enjoy controversy for its own sake; I think it usually distracts from actual important work. I especially wanted to avoid an evaporative cooling effect, where a disproportionate ratio of edgy folks convinces reasonable people not to come.
My plan was then to invite & highlight folks who could balance this out — I was specifically looking for people who were “warm, kind and gracious”. Some of our invited guests, including Katja Grace, Misha Glouberman, and Joe Carlsmith, do a good job of embodying these virtues; I think I could have have pushed farther in this direction. I’m also extremely grateful for our attendees who hosted casual fun events for each other like wrestling in the park, conflict improv, and Blood on the Clocktower — their actions spoke much, much louder than the words of two journalists who didn’t even bother to come.
Despite all this controversy, I’m very heartened that the anonymous reviewer still found our attendees to be “extremely friendly”, and that they’re interested in coming back next year. We haven’t even decided yet if there will be a Manifest 2025, but if so, I’m hoping that it retains a spirit of festivity, of fun, and of friendly intellectual disagreement.
Aside: Is Manifest an Effective Altruism event?
Mostly not, I think.
- Manifest 2024 was jointly organized by Manifold Markets (a for-profit tech startup which runs a platform for prediction markets), and Manifund (a nonprofit philanthropy that makes grants and experiments with funding mechanisms).
- The core organizing team — Rachel, Saul, and I — are proudly EA. For example, we’ve all taken the GWWC pledge, and volunteered, attended, or spoken at past EA Globals. Rachel and Saul organized for their respective university’s EA groups.
- We’ve also invited many speakers who we respect for their work in EA areas, including Scott Alexander, Katja Grace, Ajeya Cotra and Joe Carlsmith; and expect that many EA folks would enjoy Manifest.
- However, we do not market Manifest specifically as “an EA event” — that is, insofar as there is a main subject, the subject is prediction markets & forecasting. I would guess that about 15-25% of attendees self-identify as EA.
- Manifest has not been sponsored by any EA funders; all funding to date has come from individual ticket sales or our corporate sponsorships. For what it’s worth, I do think the festival was quite good by EA lights, for the talks it produced, relationships it fostered and community it built.
Because others here are unlikely to do so, I feel like I ought to explicitly defend Hanania's presence on the merits. I don't find it "fun" that he's "edgy." I go out of my way, personally, to avoid being edgy. While I tread into heated territory at times, I have always made it my goal to do so respectfully, thoughtfully, and with consideration for others' values. No, it's not edginess or fun that makes me think he belongs there. He unquestionably belongs at a prediction market conference because he has been a passionate defender of prediction markets in the public sphere and because he writes to his predominantly right-leaning audience in ways that consistently emphasize and criticize the ways they depart from reality.
Let me be clear: I emphatically do not defend all parts of his approach and worldview. He often engages in a deliberately provocative way and says insensitive or offensive things about race, trans issues, and other hot-button topics on the right. But I feel the same about many people who you would have no problem seeing attend Manifest, and he brings specific unusual and worthwhile things to the table.
My first real interaction with Hanania, as I recall, came when he boosted and praised my affirmative defense of surrogacy, a topic very personal to me and one online public figures are much more likely to attack or stay silent on than defend when I speak about it. Later, I went on his podcast to discuss my path out of Mormonism and my sexuality, my essay on how the Republican Party is doomed, the importance of a spirited defense of liberalism in the public sphere, and other ideas that would challenge his right-leaning audience and encourage norms I believe the EA sphere would approve of. This is also true of some areas where I can't claim to be as emphatically EA-aligned as he is, as with his treatise against factory farming and animal suffering.
Someone below pointed out that you misrepresented his pronouns/genocide essay, which I saw as an unusually self-reflective look at why he and others have, as he puts it, "deranged" priorities in getting the most animated not about objectively the most important ideas but about emotionally salient topics close to home. The point of the essay is not "they/them pronouns are worse than genocide," but "it is in one sense deranged, but human and important to understand, that people get so much more emotionally invested in issues like they/them pronouns than about genocide."
I understand perfectly well why people dislike him and I have no problem with robust criticism and even condemnation of much of what he says. But while his actions look from your angle like mainstreaming far-right ideas, they look to the far-right like mainstreaming animal suffering concerns, prediction markets, abortion and surrogacy, open borders, and rather a lot more. You may discount those as trivial, but the people in his audience certainly do not.
You seem smart, capable, and knowledgeable about prediction markets. I think Manifest would benefit from having you in attendance. But my own intellectual life is richer for the opportunity to read, engage with, and argue with people like Hanania. I'm glad he was there, I'm glad I had the chance to say hi to him and chat a bit, and if a precondition for your engagement is that it's either you or him, I would rather you not attend than that you use your reputational sway to prevent me from having those interactions.
