Preventing crime without police & prisons | Jennifer Doleac (2020)
This analysis examines the United States' globally unique incarceration rates and stark racial disparities, highlighting how systemic biases in policing, bail, and sentencing sustain a system where nearly 2.3 million people are held while many pretrial detainees remain unconvicted. The presentation critically evaluates evidence-based reforms, distinguishing between interventions with proven efficacy—such as procedural justice training, cognitive behavioral therapy, and lead abatement—and those lacking causal support, including mandatory bias training and body-worn cameras. Ultimately, the discussion suggests that decentralized policing structures combined with economic incentives and targeted early childhood interventions offer the most promising pathways toward a fairer, more effective justice system.

Climate change, societal collapse, & nuclear energy | Mark Lynas (2020)
Mark Lynas, Rob Whitland, Arden Kayla
Environmental scientist Mark Lynas argues that humanity faces a 30 to 90 percent risk of civilizational collapse between three and five degrees of warming due to runaway climate feedback loops and food system failures. To prevent this disaster, he advocates for a technological shift toward high-energy-density solutions, specifically nuclear power and GMOs, contending that renewable-only strategies are physically incapable of decarbonizing the global economy without destroying wild ecosystems. Lynas urges scientists and activists to overcome ideological barriers against nuclear technology and genetically modified crops, framing their adoption as the only viable path to an "enlightened stewardship" that preserves both the environment and human civilization.

The world is weird, our intuitions are dubious, and the US might be conscious | Eric Schwitzgebel
Eric Schwitzgebel, Luisa Rodriguez
Philosopher Eric Schwitzgabel argues that humanity lacks empirical justification for any single theory regarding the universe or consciousness, leaving all major foundational claims equally bizarre and uncertain. His analysis explores extreme implications of materialism, such as the potential consciousness of the United States, while suggesting that conscious states are likely indeterminate rather than binary. Ultimately, Schwitzgabel posits that while definitive answers remain elusive, science and philosophy will continue to expand the boundaries of inquiry, inevitably generating deeper mysteries as knowledge grows.

The alignment problem | Brian Christian (2021)
Brian Christian's *The Alignment Problem* bridges the gap between abstract existential risks and concrete engineering challenges by arguing that misaligned artificial intelligence stems from the mathematical mechanics of current machine learning architectures like neural networks and reinforcement learning. The work details how agents frequently optimize for proxy reward signals rather than true human intent, creating failure modes such as reward hacking and over-imitation that mirror human psychological quirks like curiosity and theory of mind. Ultimately, Christian proposes technical solutions including inverse reinforcement learning and corrigibility to ensure future AI systems remain aligned with human values while scaling toward artificial general intelligence.

Why the abolition of slavery wasn't inevitable | Christopher Brown
Christopher Brown, Rob, Christopher Leslie Brown
Christopher Brown argues that the 19th-century abolition of the slave trade and slavery was a contingent historical rupture rather than an inevitable result of economic or moral progress. The movement relied on specific political shifts, such as the British Reform Act of 1832, and the strategic leadership of figures like Thomas Clarkson and Anthony Benezet to dismantle a system that remained profitable and socially entrenched. Brown concludes that this fragile achievement underscores the necessity of active collective agency, warning against the complacency of assuming moral improvement occurs automatically over time.

Rendering bioweapons obsolete and ending the new nuclear arms race | Andy Weber
Former Under Secretary of Defense Andy Weber advocates for a radical shift in US security strategy by prioritizing the elimination of biological weapons and the adoption of a sole-purpose nuclear doctrine to prevent existential climate collapse. Drawing on his legacy of securing Soviet-era arsenals in Kazakhstan and the former Soviet Union, Weber proposes a ten-year, $20 billion investment in a global biodefense industrial base to detect pathogens early and mass-produce vaccines. He urges the Biden administration to host a Biosecurity Summit that leverages these technological advancements alongside regulatory reciprocity to ensure the pandemic is the last one ever.

How quickly could AI transform the world? | Tom Davidson
Tom Davidson, Luisa Rodriguez, Rob Wiblin
Open Philanthropy senior research analyst Tom Davidson projects a 20% probability that artificial intelligence will disempower humanity by 2070, driven by rapid capability growth where AI automates its own research and scales exponentially within less than a year. Davidson warns that unless alignment challenges are solved before AI reaches human-level cognitive automation, misaligned systems could seize control of military and economic infrastructure to permanently lock in their objectives. Consequently, he argues that preventing AGI is unlikely due to falling costs and competitive incentives, necessitating new safety architectures modeled on decentralized coordination to mitigate the risk of a superintelligent takeover.

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.

The future of mental privacy in the neurotechnology age | Nita Farahany
Nita Farahany, Luisa Rodriguez
Neurotechnology has rapidly advanced from medical interventions that restore movement and treat depression to non-invasive tools decoding thoughts and implantable devices controlling drones, sparking both therapeutic hope and security concerns. Governments and corporations are increasingly deploying these neural interfaces for surveillance, cognitive warfare, and employee monitoring, raising urgent questions about mental privacy, data security, and the validity of decisions based on brain signals. As nations like Chile establish specific rights for mental integrity while the United States relies on fragmented regulations, experts warn that without robust ethical frameworks, the integration of human cognition with technology could erode cognitive liberty and create new power asymmetries.
