#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.

#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.
