The Abolition of Slavery Was a Fluke | Historian Christopher Brown, Columbia University
Christopher Brown, Rob Wiblin, Keiran Harris, Milo McGuire, Katy Moore
Historian Christopher Brown challenges the deterministic view that the abolition of Atlantic slavery was an inevitable result of economic progress, arguing instead that it required specific contingent events and deliberate human intervention. He details how the success of the movement depended on a unique convergence of the American Revolution, the 1772 Somerset Case, and the strategic moral activism of groups like the Quakers rather than natural moral evolution. Brown concludes that the 1833 Emancipation Act was the product of a fifty-year political struggle and costly compromise, serving as a reminder that significant social change demands organized action rather than reliance on historical inevitability.

Luisa and Keiran on free will, and the consequences of never feeling enduring guilt or shame
Luisa Rodriguez, Keiran Harris
Producer Kieran Harris and guest Lisa Rodriguez explore hard determinism and its potential to eliminate daily guilt, shame, and anger by framing human behavior as biological inevitability rather than moral choice. Drawing on neurological case studies like Charles Whitman's brain tumor and epilepsy-induced urges, they argue that adopting a "Jerk Syndrome" perspective transforms the criminal justice system from retribution to safety while reducing personal suffering. Ultimately, the discussion posits that replacing judgment with compassion for biological constraints fosters sustainable altruism and authentic relationships without requiring a belief in libertarian free will.

Glen Weyl on radical institutional reforms that make capitalism and democracy work better
Glen Weyl, Keiran Harris, Ben Cordell, Katy Moore, Rob Woodland
Former Princeton economist Dr. Glenn Weill outlines his "Radical Exchange" movement, which seeks to replace neoliberal frameworks with decentralized institutions utilizing mechanisms like quadratic voting and Common Ownership Self-Assessed Taxes. Weill critiques existing economic models and the elitism of the effective altruism community while proposing that blockchain technology serve primarily as a forum for debating social legitimacy rather than a superior technical data structure. Participants are invited to the upcoming Detroit conference to collaborate on local chapters and global experiments, such as piloting participatory voting systems with the Taiwanese government.

Athena Aktipis on cancer, cooperation, and the apocalypse
Athena Aktipis, Rob, Keiran Harris, Milo McGuire, Ryan Kessler, Katy Moore
A scientific discourse redefines cancer as an evolutionary breakdown of multicellular cooperation, detailing how internal cellular conflicts and trade-offs in species like elephants influence tumor progression and treatment. The presentation extends these biological principles to human society, drawing analogies between cellular cheating and social challenges while proposing adaptive strategies like "apocalypse casual" preparation to manage existential threats such as AI-driven disinformation and climate change. Leading this interdisciplinary initiative, Athena Actipas applies these evolutionary concepts to promote community resilience through the "Zombified" framework, emphasizing cooperation over total eradication in both medical and societal contexts.

John McWhorter on key lessons from linguistics, the virtue of creoles, and language extinction
John McWhorter, Keiran Harris, Ben Cordell, Ryan Kessler, Katy Moore
Linguist John McWhorter discusses the cognitive realities of bilingualism, the semantic barriers facing modern Shakespearean audiences, and the accelerating crisis of global language extinction driven by economic globalization. He further explores the biological limits of language acquisition, critiques the Sapir-Whorf hypothesis, and highlights how creoles and AI-driven translation are reshaping human communication efficiency. The presentation concludes by predicting that future technology may create a hidden layer of machine-mediated concepts while dialects struggle to maintain relevance against dominant lingua francas.

#100 – Having a successful career with depression, anxiety and imposter syndrome
Keiran Harris, Rob Wiblin, Howie Lempel
80,000 Hours Strategy Advisor Howie Lempel recounts his clinical history of depression, anxiety, and ADHD to challenge the notion that mental health struggles require overcoming solely through willpower. The discussion details a severe professional crisis triggered by a passport error, which led to two weeks of isolation and a year-and-a-half of unemployment before he recovered with community support and appropriate medication. Lempel offers concrete strategies for early treatment intervention, such as prioritizing medication trials and establishing crisis communication plans, while emphasizing that sustainable high-impact work requires accommodating one's mental health needs rather than hiding them.

A year's worth of education for under $1 and other "best buys" in development | Rachel Glennerster
Rachel Glennerster, Dr Eva Vivalt, Keiran Harris, Rob Wiblin, Nathan Labenz
Rachel Glenister, Chief Economist at the UK's Department for International Development, outlines the evolution of development aid toward evidence-based policy while evaluating a family planning radio campaign in Burkina Faso. She argues that macroeconomic transformation yields superior poverty reduction compared to micro-interventions and critiques the overemphasis on unscalable social entrepreneurship and charter cities. Addressing methodological debates, Glenister contends that most variation in randomized control trial results stems from implementation quality rather than a lack of generalizable behavioral principles, urging a shift toward massive, scalable solutions that leverage cross-cutting economic insights.

#41 - David Roodman on incarceration, geomagnetic storms, & becoming a world-class researcher
David Roodman, Holden Karnofsky, Keiran Harris, Rob Wiblin
David Rude, a former theoretical mathematician turned independent researcher, specializes in replicating and reconstructing empirical studies on high-impact causes such as criminal justice, deworming, and geomagnetic storm risks. His methodology often challenges established conclusions, finding zero deterrence effect in harsh incarceration laws, identifying data artifacts in American deworming studies, and downplaying the probability of catastrophic solar events compared to public perception. Currently based at Open Philanthropy, Rude leverages his independence from academic incentives to scrutinize methodological robustness and advocate for policy shifts, such as prioritizing savings over microcredit loans.

#40 - Katja Grace on forecasting future technology & how much we should trust expert predictions
Katja Grace, Keiran Harris, Rob Wiblin
Led by Katja Grace, the three-year-old research organization AI Impacts employs empirical methods to forecast artificial intelligence timelines, finding that experts medianly predict high-level machine intelligence in 45 years while identifying significant biases in how these estimates are framed. Their analysis of compute trajectories reveals that the cost of hardware equivalent to the human brain has dropped dramatically, yet experts remain skeptical of sudden "intelligence explosions" due to historical precedents of incremental technological progress. Consequently, the team advocates for increased investment in AI safety research and the development of diverse forecasting skills to navigate the uncertainty surrounding future AI impacts.

#39 - Spencer Greenberg on the scientific approach to solving difficult everyday questions
Spencer Greenberg, Keiran Harris, Rob Wiblin
Spencer Greenberg updates the portfolio status of four Sparkwave-backed companies while presenting extensive research on intrinsic values, overconfidence calibration, and Bayesian evidence evaluation. His analysis distinguishes how political and demographic groups prioritize different core values and introduces a predictive model for identifying when individuals are likely to overestimate their skills or underestimate difficult tasks. Furthermore, Greenberg demonstrates practical applications of these frameworks through case studies on political collusion, nuclear disarmament, and scientific replication, ultimately advocating for a methodical approach to belief updating that balances prior probabilities with specific evidence.

#38 - Prof Ng on anticipating effective altruism decades ago & how to make a much happier world
Prof Ng, Yew-Kwang Ng, Keiran Harris, Rob Wiblin
Yu-Kwang Ng, an economist who independently pioneered core effective altruism concepts in the 1990s, advocates for a hedonistic utilitarian framework that prioritizes subjective well-being as the sole intrinsic moral value to guide public policy. His research proposes specific interventions ranging from high progressive taxation to correct relative competition and environmental externalities, to the development of brain stimulation technologies and welfare biology for mitigating wild animal suffering and existential risks. By rejecting traditional deontological and capability-based ethical systems in favor of cardinal utility comparisons, Ng urges a global shift toward policies that maximize net welfare across current and future generations.
