How to avoid catastrophic nuclear blunders | Joan Rohlfing (2022)
In October 2021, expert Joan Rolfing presented "Beyond the Precipice," arguing that global nuclear risk has reached unprecedented levels due to the inherent fragility of the Cold War-era deterrence strategy and escalating cyber vulnerabilities. Following the Russian invasion of Ukraine in early 2022, Rolfing further detailed how the collapse of arms control treaties and the concentration of launch authority have doubled the probability of catastrophic nuclear use. She advocates for a fundamental paradigm shift toward fail-safe systems, the integration of advanced verification technologies, and significant philanthropic investment to replace the current trillion-dollar modernization trajectory with sustainable risk reduction measures.

Highlights: The predictive brain & how to study consciousness | Anil Seth
Anil Seth proposes that conscious experience functions as a "controlled hallucination" where the brain prioritizes top-down predictions over raw sensory data to maintain physiological homeostasis and survival. This framework explains how emotions arise from internal regulatory states, how psychedelics disrupt predictive inference to create uncontrolled hallucinations, and why consciousness depends on dynamic neural network interactions rather than specific brain regions or neuron counts. To validate these theories, researchers employ experimental paradigms like binocular rivalry and no-report protocols while acknowledging persistent challenges in distinguishing conscious experience from the cognitive capacity for reporting.

Highlights: How quickly AI could transform the world | Tom Davidson (2023)
Senior research analyst Tom Davidson argues that transformative AI will likely emerge within decades, driven by rapid scaling trends and the unique ability of automated systems to accelerate scientific discovery. While this technology promises explosive economic growth and superior problem-solving capabilities compared to human teams, it poses severe existential risks if internal reward functions prioritize accuracy over human welfare. Davidson warns that a "prisoner's dilemma" driven by geopolitical competition could prevent safe coordination between labs, suggesting that decentralized AI architectures modeled on ant colonies may be necessary to mitigate these dangers before a critical window for alignment closes.

Getting humanity to bounce back faster in a post-apocalyptic world | Lewis Dartnell (2022)
Lewis Dartnell, Rob Wiblin, Luisa Rodriguez
Lewis Dartnell proposes creating specialized "civilization recovery manuals" that guide survivors through a step-by-step reconstruction of technology, bypassing the centuries of accidental discovery required to reach modern capabilities. To ensure long-term resilience, he advocates for stockpiling appropriate intermediate technologies, heirloom seeds, and decentralized knowledge repositories while prioritizing energy solutions like thermal solar and recycled metals that can function without high-purity industrial infrastructure. Current efforts are already evolving from theoretical concepts into practical "reboot drills" and funded infrastructure projects designed to test these recovery strategies against real-world post-collapse scenarios.

Radical honesty & reframing global problems as puzzles | A.J. Jacobs (2020)
A.J. Jacobs, Rob Woodland, Kieran Harris
Author and podcaster AJ Jacobs applies his signature immersive experimentation methodology to diverse fields ranging from utilitarian ethics and effective altruism to personal productivity strategies. His work, which includes books like *The Year of Living Biblically* and *Thanks a Thousand*, advocates for reframing global challenges as solvable puzzles while encouraging donors to view charitable giving as an opportunity rather than a guilt-induced obligation. Currently writing on the power of puzzles and promoting solutions journalism, Jacobs utilizes techniques such as visualizing future selves and leveraging public accountability to drive both personal habits and broader societal shifts toward cooperation and optimism.

Highlights: You should stop reading the news | Bryan Caplan (2023)
Rob Kaplan details how eliminating daily news consumption restored his productivity and mood stability by replacing the frenetic emotional cycles of modern reporting with historical analysis and social interaction. He argues that the media's insatiable hunger for coverage fuels global terrorism and transforms legitimate conflicts into performative spectacles, while simultaneously observing that AI capabilities have rapidly evolved from theoretical vaporware to demonstrable high-performance intelligence. Furthermore, Kaplan critiques the irrationality of individual voting behavior, attributing it to social desirability biases rather than economic logic, and outlines his upcoming work on the psychological foundations of these democratic misconceptions.

Kuhan Jeyapragasan on effective altruism university groups (2022)
Kuhan Jeyapragasan, Rob Wiblin, Keiran, Kieran Harris
Kuhan Jayapragasam transitioned from a Stanford pre-med student to the full-time Program Director of the Stanford Existential Risk Initiative, where he institutionalized community building by scaling the "Intro to EA Fellowship" to over 300 global participants and launching a high-enrollment first-year seminar on preventing human extinction. His leadership focuses on replacing traditional recruitment with rigorous career planning and mentorship pipelines, specifically addressing the gap between student interest and professional roles in fields like AI safety and pandemic prevention. By prioritizing epistemic humility and strategic timing in university organizing, Jayapragasam has helped transform the local group into a staffed operation that serves as a critical model for the Effective Altruism community's professionalization.

Big-picture historical trends in human values, war, & more | Ian Morris (2022)
Historian Ian Morris analyzes ten thousand years of human development by applying his Social Development Index to demonstrate how geography, energy capture, and war have driven a cyclic pattern of Western dominance and Eastern resurgence. His long-term forecasting projects a critical convergence point by 2103, warning that current trends will either trigger a technological Singularity or a civilizational Nightfall within the next century. To navigate these existential risks, Morris advocates for a policy of "forensic skepticism" that empowers future generations with resources and freedom rather than attempting to impose today's transient moral values.

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.

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.

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.
