#15 - Prof Tetlock on how chimps beat Berkeley undergrads and when it’s wise to defer to the wise
Prof Tetlock, Prof Philip Tetlock, Keiran Harris, Rob Wiblin, Philip Tetlock
Spanning 35 years of research on over tens of thousands of participants, Philip Tetlock's program utilizes Brier scores to demonstrate that while most experts and hedgehogs perform no better than chance, a specific subset of adaptable "superforecasters" consistently outperforms intelligence analysts through rigorous training and cognitive diversity. These findings inform a new IARPA-sponsored hybrid tournament that pits human-machine teams against each other in quantitative and idiosyncratic domains to identify the most effective forecasting methods. Ultimately, the research underscores the necessity of calibration and open-mindedness over ideological certainty, advocating for structured aggregation systems to mitigate the dangers of overconfident punditry in complex macro-political landscapes.

#6 - Dr Toby Ord on why the long-term future matters more than anything else & what to do about it
Dr Toby Ord, Keiran Harris, Rob Wiblin
The presentation argues that the 21st century represents a pivotal era where humanity faces a roughly one-in-six probability of extinction from anthropogenic threats like artificial intelligence, synthetic biology, and nuclear conflict. It posits that this existential risk is uniquely high because current technological power has outpaced civilizational wisdom, necessitating immediate global coordination and targeted interventions to preserve the potential value of a multi-million year future. By reframing long-term survival as a moral imperative, the argument advocates for specific career paths and institutional reforms that prioritize managing these catastrophic risks over short-term gains.

#25 - Prof Robin Hanson on why we have to lie to ourselves about why we do what we do
Robin Hanson, Rob Wiblin, Kevin Simler
Robin Hanson argues that human behavior across education, religion, and charity is driven primarily by subconscious signaling motives to avoid violating social norms rather than by stated functional goals. This evolutionary framework explains why institutions prioritize credentialing and ritual over actual efficacy, creating a disconnect between conscious narratives and the real drivers of reproductive fitness and social status. To address these inefficiencies, Hanson proposes implementing decision markets and "marginal charity" strategies that align individual signaling incentives with tangible societal improvements while bypassing the political resistance of established elites.
