#30 - Dr Eva Vivalt on how little social science findings generalize from one study to another
Dr Eva Vivalt, Keiran Harris, Rob Wiblin
Y Combinator launched a $100 million, three-to-five-year randomized controlled trial providing $1,000 monthly to approximately 1,000 low-income young adults to analyze shifts in time use, health, and well-being while deliberately withholding results until the study's conclusion to prevent narrative distortion. This initiative is situated within a broader academic discourse highlighting the limited generalizability of development interventions and the prevalence of optimism bias among policymakers, who often neglect variance and negative results in favor of optimistic point estimates. Experts argue that despite these methodological challenges and academic incentives prioritizing novelty over synthesis, aggregated expert priors and robust RCTs remain essential for refining evidence-based policy and overcoming the "naturalistic heuristic" in emerging fields like clean meat adoption.

#29 - Dr Anders Sandberg on 3 new resolutions for the Fermi paradox & how to colonise the universe
Dr Anders Sandberg, Keiran Harris, Rob Weblin
Anders Sandberg and Toby Ord reframe the Fermi Paradox by replacing flawed point estimates with probability distributions, suggesting an 8% to 30% chance that humanity is the only intelligent life in the universe. Their analysis identifies an early "Great Filter" regarding the emergence of intelligence while evaluating speculative solutions like cosmic estivation or defensive berserker mechanisms that remain consistent with current astronomical silence. Beyond extraterrestrial speculation, the discussion establishes critical methodological lessons for risk assessment, urging reliance on multiple independent arguments to avoid catastrophic errors in predicting existential threats like pandemics or uncontrolled self-replicating technologies.

#26 - Marie Gibbons on how exactly clean meat is made & whats needed to get it in every supermarket
Marie Gibbons, Natalie Cargill, Keiran Harris, Rob Wiblin
Marie Gibbons predicts that cell-based meat will reach the consumer market by year-end at a premium price, with production costs expected to achieve parity with conventional meat within a decade through improved bioreactor scaling and media optimization. The technology relies on harvesting satellite cells via humane biopsy and utilizing plant-based scaffolds to create initial burger formats, while future whole-cut developments depend on overcoming growth factor dependencies through recombinant proteins or genetic editing. Gibbons emphasizes that accelerating this transition requires coordinated industry efforts across major research hubs in Boston and London to prioritize species-specific biological protocols and reduce animal suffering more effectively than advocacy alone.

#25 - Prof Robin Hanson on why we have to lie to ourselves about why we do what we do
Robin Hanson, Kevin Simler, Keiran Harris, Rob Wiblin
Robin Hanson and Kevin Simler propose in *The Elephant in the Brain* that human institutions like education, medicine, and charity function primarily as signals of status and virtue rather than fulfilling their stated goals. By exposing how self-deception and hidden motives sustain these systems, the authors argue that effective reform requires designing policies that allow individuals to maintain their high-minded self-image while actually achieving better real-world outcomes. This perspective challenges conventional wisdom across sociology and futurology, urging a shift from abstract idealism to pragmatic strategies aligned with true human incentives.

#24 - Stefan Schubert on why it’s a bad idea to break the rules, even if it’s for a good cause
Stefan Schubert, Keiran Harris, Rob Wiblin
Stefan Schubert examines the tension between epistemic modesty and effective altruism's cultural cohesion, warning that overconfidence and political tribalism threaten the movement's rational foundations while urging a shift toward specialized expertise. He analyzes organizational trends where talent gaps now overshadow funding constraints and highlights the slow pace of "creative destruction," noting that the community's reputation for integrity remains a fragile asset that demands strict adherence to norms over short-term gains. Ultimately, Schubert clarifies the concept of cause neutrality to argue that deep confidence in existential risks like AI safety can coexist with a willingness to update beliefs, provided the movement avoids irreversible political entanglements and continues expanding its reach into the developing world.

#22 - Dr Leah Utyasheva on the non-profit that figured out how to massively cut suicide rates
Dr Leah Utyasheva, Keiran Harris, Rob Wiblin
Founded in 2016 by Leah Utyasheva and Professor Michael Eddleston, the Centre for Pesticide Suicide Prevention advocates for banning highly toxic Class 1A pesticides to address the 150,000 annual deaths caused by impulsive agricultural self-poisoning. Backed by a GiveWell grant and affiliated with the University of Edinburgh, the organization is collecting hospital data from India and Nepal to demonstrate that restricting access to these lethal means is a cost-effective strategy, having already saved 93,000 lives in Sri Lanka. This evidence-based approach aims to persuade local regulators to prioritize means reduction over ineffective safe storage measures, thereby relieving overwhelmed health systems and fulfilling government obligations to protect citizen safety.

#20 - Bruce Friedrich on inventing outstanding meat substitutes to end speciesism & factory farming
Bruce Friedrich, Natalie Cargill, Keiran Harris, Rob Wiblin
The Good Food Institute executes a strategy to displace industrial animal agriculture by accelerating the development of plant-based and clean meats that compete on price, taste, and convenience rather than ethical appeal. While current market share for alternatives remains below 1% amidst a record 9 billion annual animal slaughters, industry experts project cost parity with conventional meat within a decade through bioreactor scaling and synthetic biology. Operating as a rapidly expanding nonprofit funded entirely by philanthropy, the organization targets a 2050 vision where these technologies collectively fulfill 100% of global meat demand.

#17 - Prof Will MacAskill on moral uncertainty, utilitarianism & how to avoid being a moral monster
Prof Will MacAskill, Will MacAskill, Rob Wiblin
Will McCaskill reflects on the transition of the Effective Altruism movement from its origins in GiveWell and Giving What We Can to its current status as a global network, while stepping down as CEO of the Center for Effective Altruism to pursue academic leadership in moral uncertainty research. He argues that decision-making should analogously apply expected value reasoning to moral theories, proposing a "Long Reflection" era where humanity resolves fundamental value questions before committing to irreversible actions. Despite these theoretical advances, McCaskill emphasizes the necessity of addressing critiques regarding justice, institutional bias, and the need for greater diversity to prevent the community from stagnating in groupthink.
