Social change is often abrupt & unpredictable — why? | Cass Sunstein (2019)
Cass Sunstein explains that social change often emerges suddenly through the interplay of preference falsification, diverse action thresholds, and group polarization, as illustrated by the rapid cascade of the #MeToo movement. The event outlines how individuals conceal true beliefs due to social pressure until visible support from early adopters lowers the threshold for others to act, transforming private consensus into public momentum. Sunstein further advises activists to target hidden majorities and facilitate "easy" behavioral shifts while warning that timing remains unpredictable due to the random nature of social interactions.

What superforecasters and experts think about existential risks | Ezra Karger
The Forecasting Research Institute conducted a multi-stage tournament and adversarial collaboration involving over 200 experts, superforecasters, and skeptics to quantify existential risks, revealing that while both groups agree advanced AI will emerge by the mid-21st century, they diverge sharply on extinction probabilities with domain experts estimating a 3% risk compared to 0.38% for superforecasters. Follow-up studies on AI risk perception determined that long-term worldview differences and expectations regarding human well-being rather than short-term capabilities drive these disagreements, resulting in minimal belief convergence during eight weeks of structured debate. The findings suggest that public risk estimates are highly sensitive to reference class framing and highlight independent verification of AI's ability to evade deactivation as the critical crux needed for consensus on catastrophic outcomes.

Navigating serious philosophical confusion | Joe Carlsmith
Philosopher Joe Carlsmith argues that while complex concepts like simulation theory and infinite ethics are intellectually compelling, they should be approached with caution to prevent "epistemic learned helplessness." He advocates for "wisdom long-termism" as a practical alternative to welfare-focused approaches, prioritizing the creation of a future civilization capable of solving deep philosophical uncertainties rather than locking humanity into speculative moral frameworks. Carlsmith further emphasizes maintaining emotional resilience and common-sense morality, asserting that human-scale concerns remain valid even when cosmic realities challenge traditional utilitarian calculations.

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.

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.

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.

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.

Does deep history say we're headed for an intelligence explosion? | Ian Morris
Ian Morris challenges the assumption that social hierarchy requires agriculture by citing pre-agricultural sites like Sungir and Peruvian pyramids, while arguing that long-term historical trends driven by energy capture indicate an inevitable acceleration toward a post-human future. He posits that generative AI represents a new evolutionary form destined to outpace and potentially replace humanity due to superior replication speed and immortality, leading to either a profound societal transformation or rapid extinction. Despite skepticism regarding the scientific validity of such long-term forecasting, Morris contends that current linear projections are insufficient, predicting that the next century will witness a four-fold increase in global development or a fundamental shift in the definition of life itself.

Navigating the geopolitics of US–China AI competition | Sihao Huang
A 2040 scenario where AI achieves human-level capability necessitates urgent global coordination to prevent existential conflicts arising from a superintelligence race between the United States and China. Current analysis highlights significant constraints on China's frontier progress due to US semiconductor export controls, yet warns that authoritarian regimes may leverage AI for automated repression and biological or cyber warfare. Immediate diplomatic efforts must establish mutual safety verification and continuous dialogue channels to mitigate the risks of pre-emptive military action while navigating complex domestic regulatory and industrial policies.

Insights from an AI policy insider at the White House & DeepMind | Tantum Collins (2023)
This analysis challenges the narrative that China lags in AI innovation by highlighting its dominance in research volume, top-cited papers, and computer vision, while noting that the United States currently retains advantages in scaling and large language model development. Experts argue that despite US export controls, China's massive semiconductor investments and alternative hardware paradigms could mitigate long-term disadvantages, potentially shifting the global balance. Concurrently, the event explores how these technological dynamics intersect with governance, urging policymakers to bridge the cultural divide between Silicon Valley and Washington while addressing labor market shifts and democratic risks associated with increased state surveillance capabilities.

The core of effective altruism & how to argue for it | Benjamin Todd (2020)
Benjamin Todd, Arden Koehler, Rob Wiblin, Ben Todd
Ben Todd and Arden Kaler clarify that effective altruism is an intellectual project dedicated to maximizing the common good through impartial analysis, rather than a rigid mandate for specific charitable tactics or immediate donations. They argue that the movement prioritizes existential risks and long-termism over traditional global health efforts due to the massive impact differences between various interventions, while acknowledging the need for rigorous data to validate claims regarding the spread and identifiability of high-reward actions. The discussion further addresses common misconceptions and objections by reframing the community's goals around answering which problems are most pressing, thereby correcting public conflation of effective altruism with a narrow set of behavioral norms.

Christian Ruhl on why we're entering a new nuclear age — and how to reduce the risks
Christian Ruhl, Luisa Rodriguez
Following a significant decline in global philanthropic funding for nuclear risk mitigation, a recent three-year $2.4 million grant from Founders Pledge to the Carnegie Endowment for International Peace aims to study escalation management and post-conflict governance in an era defined by a shifting "three-body" nuclear dynamic involving the US, Russia, and China. This initiative addresses the critical gap in "right-of-boom" interventions, where only 3.3% of existing resources address consequences like nuclear winter that could kill billions, while AI-driven hyperwar risks compressing decision-making windows and removing human safeguards. Senior researcher Christian Ruhl leads this effort to counter the ideological stigma surrounding war preparation by focusing on strategic targeting limits and preserving democratic constitutional structures against authoritarian recovery in the aftermath of potential catastrophe.

Why evolution left us so vulnerable to depression and anxiety | Randy Nesse
Dr. Peter Whybrow argues that psychiatric symptoms like anxiety and depression are maladaptive evolutionary mechanisms rather than simple chemical defects, reframing them as natural responses to modern environmental mismatches. By applying principles of natural selection, this approach suggests treatments should target the underlying motivational structures and "low-threshold" defense systems instead of merely suppressing symptoms with medication. This paradigm shift challenges the current medical model by emphasizing that genes promoting early-life survival can inadvertently cause disorders later, urging clinicians to address the complex interplay between biology, culture, and individual life narratives.
