The most common misconceptions about nuclear war | Jeffrey Lewis (2022)
Jeffrey Lewis critically reinterprets US nuclear strategy as a system driven by bureaucratic pathologies and intra-service rivalry rather than coherent game theory, exposing the obsolescence of Cold War concepts like Mutual Assured Destruction in modern policy. He advocates for specific reforms including a presidential declaration restricting nuclear use to situations where conventional weapons fail, ratification of the Comprehensive Nuclear Test Ban Treaty, and limits on missile defenses to stabilize strategic relations with China. Lewis urges the effective altruism community to apply quantitative rigor and open-source intelligence to these issues while avoiding partisan disarmament frames that hinder progress on reducing existential nuclear risks.

Highlights: Edge cases of sentience & acting ethically despite massive uncertainty | Jonathan Birch
Philosophy professor Dr. Jonathan Birch presents *The Edge of Sentience*, a work analyzing how "inductive risk" has historically led medical and scientific experts to undervalue potential suffering in neonates, vegetative patients, and animals due to overconfidence in current consciousness models. Drawing on cases like Jill Lawson's advocacy and Adrian Owen's fMRI research, Birch highlights the dangers of relying solely on expert consensus by proposing that citizens' assemblies should complement scientific input when setting bioethics policies for emerging technologies like neural organoids and artificial general intelligence. The book further argues for separating the legal right to abortion from debates on fetal sentience to prevent future scientific advancements from eroding bodily autonomy protections.

SB 1047: California's AI bill & its potential to shape US AI policy | Nathan Calvin
Nathan Calvin, Luisa Rodriguez
California Senate Bill 1047 mandates that developers of AI models requiring over $100 million in compute resources implement rigorous safety assessments, third-party audits, and emergency shutdown protocols to mitigate critical harms defined as mass casualties or damages exceeding $500 million. Sponsored by Senator Scott Weiner with backing from prominent safety researchers and labor unions, the legislation codifies a negligence-based liability framework that forces covered entities to publish test results and maintain guardrails without creating a new regulatory agency. Although opposed by major industry players and some politicians who fear stifling innovation or interfering with federal authority, the bill leverages California's market size to establish a global standard for accountable AI development before potential federal action occurs.

Air pollution is responsible for ~12% of global deaths. What can we do? | Santosh Harish (2023)
Air pollution in South Asia, particularly India, causes approximately 6.67 million global deaths annually and reduces life expectancy by three years, primarily driven by household solid fuel combustion, vehicular emissions, and transboundary atmospheric conditions trapping smog over the Indo-Gangetic Plain. Despite the severe health and economic impacts, governance has failed due to outdated 1980s legislation, under-resourced enforcement agencies, and a lack of rural monitoring data, while current mitigation efforts often rely on politically visible but scientifically ineffective measures like smog towers. Open Philanthropy addresses this neglect by funding technical assistance, low-cost sensor networks, and simplified modeling tools to help policymakers overcome capacity gaps and implement cost-effective, evidence-based interventions.

Is lazy parenting OK? | Bryan Caplan (2022)
Philosopher and author Brian Kaplan discusses his upcoming graphic novel on housing deregulation and presents a comprehensive argument that voter behavior is driven by group identity rather than material self-interest. He challenges conventional economic wisdom by asserting that parental influence on adult outcomes is largely negligible due to genetics, while immigration provides significant net benefits through cultural assimilation and labor market efficiency. Furthermore, Kaplan critiques modern effective altruism for falling prey to social desirability bias and defends a "weak deontological" framework that prioritizes individual autonomy against state paternalism.

China & AI: What we get wrong | Jeffrey Ding (2020)
Jeffrey Ding, lead China researcher at the Center for the Governance of AI at Oxford, challenges prevailing Western narratives by arguing that perceptions of China's AI dominance, a monolithic state apparatus, and an emerging AI arms race are often detached from empirical reality. Ding highlights that while the U.S. maintains strategic advantages in foundational research and open-source software, China's development follows a distinct historical trajectory shaped by fragmented local interests, specific industrial policies like the "Industrial Internet," and genuine domestic debates on AI safety and ethics. The analysis concludes that framing U.S.-China relations as a zero-sum cold war risks accelerating harmful decoupling and obscuring the complex, cross-border innovation networks that currently drive technological progress in both nations.

Edge cases of sentience & how to act ethically despite massive uncertainty | Jonathan Birch
Jonathan Birch, Luisa Rodriguez
Philosopher Jonathan Birch presents a precautionary framework in *The Edge of Sentience* that mandates proportionate moral action based on the realistic possibility of suffering in beings ranging from human fetuses and invertebrates to neural organoids and advanced AI. Drawing on evidence of diagnostic errors in disorders of consciousness and the suffering of species like octopuses and bees, Birch argues for abandoning rigid classifications in favor of a duty to avoid gratuitous harm even amidst scientific uncertainty. This approach has already influenced UK legislation to include crustaceans and cephalopods in welfare protections while recommending a shift toward citizen-led deliberation and proactive regulation for emerging technologies like brain emulation.

Unfashionable climate interventions that work & fashionable ones that don’t | Johannes Ackva (2023)
This presentation argues that climate philanthropy must shift focus from near-term emission reductions to reducing expected long-term damage by funding neglected technologies like advanced nuclear and super-hot rock geothermal to hedge against high-warming scenarios. The speakers advocate prioritizing regions with significant carbon lock-in risks, such as China and India, while directing innovation capital toward the US and EU to accelerate cost reductions in hard-to-abate sectors. By emphasizing allocative efficiency in policy advocacy and targeting early-stage innovation rather than mature deployment, the event outlines a strategy to maximize the marginal impact of limited charitable resources.

How to regulate cutting-edge AI models | Markus Anderljung (2023)
Markus Anderljung, Luisa Rodriguez, Rob, Marcus Andrew Young
The Center for the Governance of AI is mobilizing to address critical risks in frontier AI systems, such as emergent capabilities and autonomous agent loops, by advocating for a mandatory three-pillar regulatory framework covering licensing, external red-teaming, and compute governance. Driven by urgent momentum from major tech leaders and government bodies, this initiative proposes a flexible regime that mandates risk assessments and licensing for high-compute training to prevent dangerous deployment. Simultaneously, the organization is expanding its workforce by seeking interdisciplinary experts in policy, economics, and technical fields to help implement these safeguards and influence global standards.

Alex Lawsen on avoiding 10 mistakes people make when pursuing a high impact career
Alex Lawson, an advising manager from 80,000 Hours, joins host Luis Rodriguez to outline ten common cognitive traps that hinder high-impact career decisions, ranging from blindly following ranked lists to misinterpreting short AI timelines. The discussion reframes these errors as correctable patterns of thought rather than moral failures, offering evidence-based strategies for optimizing career capital, resisting the urge to switch paths, and validating personal fit through intense experimentation. By integrating insights on cause prioritization and the value of conventional mentorship, the conversation provides a framework for navigating uncertainty and maximizing long-term contribution without succumbing to moral perfectionism.

Do unconditional cash transfers cause economic growth in low-income countries? | Paul Niehaus (2023)
Paul Niehaus and USAID advocate for cash transfers as the default development strategy, supported by evidence that recipients in extreme poverty outperform traditional aid programs in asset accumulation, income generation, and subjective well-being. Recent large-scale experiments, including a UBI trial in Kenya, demonstrate a 2.5x economic multiplier effect and prove that unconditional cash does not discourage work while significantly reducing food insecurity. Although operational risks like fraud exist, organizations like GiveDirectly are addressing these through enhanced protocols and transparency, ultimately positioning cash transfers as a scalable, autonomy-respecting benchmark that forces the broader aid sector to improve its efficacy.

Altruistic perfectionism is self-defeating | Tim LeBon
This event addresses the etiology of dysfunctional and moral perfectionism within communities like effective altruism, where rigid self-worth tied to achievement fosters burnout through identity fusion and catastrophic fear. It details evidence-based Cognitive Behavioral Therapy techniques and the therapeutic application of Stoicism's dichotomy of control to reframe values and break cycles of avoidance. By contrasting outcome-focused utilitarianism with process-oriented virtue ethics, the discussion provides clinicians and individuals with structured strategies to mitigate low self-esteem and imposter syndrome while promoting sustainable well-being.

Highlights: Lewis Bollard on the 7 best ways to end factory farming
Lewis Bollard, Luisa Rodriguez
Philosopher Roger Scruton and advocate Lewis Bollard underscore a growing global consensus that factory farming is ethically indefensible, driving a shift toward pragmatic incremental reforms rather than revolutionary abolition. These strategic efforts have mobilized over 3,000 companies to adopt cage-free supply chains, currently benefiting approximately 200 million hens with a projected increase to 450 million, while simultaneously addressing the severe welfare crises facing fish and aquaculture industries. This momentum is further solidified by a recent bipartisan US Supreme Court ruling upholding California Proposition 12, which establishes a critical legal precedent allowing states to ban the sale of products from cruelly confined animals across the nation.

AI doesn't need to be 'superintelligent' to take over + AI safety playbook | Holden Karnofsky (2023)
Holden Karnofsky, currently on leave from Open Philanthropy, argues that AI safety risks stem from explosive acceleration and the ability of numerous human-level agents to outcompete humanity rather than a single superintelligent event. To counter this, he proposes a four-part intervention strategy focusing on threat assessment research, mandatory safety evaluations for model deployment, internal lab advocacy, and enhanced information security against theft. While rejecting both absolute doomerism and the notion that alignment alone solves all risks, Karnofsky advocates for flexible regulatory frameworks and a subjectivist ethical approach that balances urgent AI risks with broader moral values.
