Foreseeing and reacting to globally impactful and existential catastrophes.
Sentinel protects against difficult-to-envision threats by forecasting near-term risks, detecting black swans earlier, and deploying our emergency response team to take mitigating action.
Even during global crises, independent operators can have a big impact.
Inspired by the work of groups like VaccinateCA, who were able to save thousands of lives by disseminating vaccine information more effectively than the US government, Sentinel generalizes this approach to crises that could lead to extinction-level events.
Team
Top forecasters from Samotsvety for the foresight team, diversely-skilled operators for the emergency respose team, and an ambitious leadership team.
The Foresight team’s goal is to monitor current events, update forecasts of these events leading to large-scale and existential catastrophes, alert the emergency response team when they deem the risk high enough, and support the emergency response team with ongoing forecasts if necessary. Crucially, the time-scales on which the Foresight team forecasts is that which judgmental forecasting is best suited to. Examples of events that could escalate into global risks are the invasion of Ukraine, cyberattacks/malfunctions, North Korean missile tests, or Sam Altman joking that “AGI has been achieved internally”.
In the event of a potentially upcoming catastrophe, the Foresight team alerts the Emergency Response team, then the public, then proceeds to work with the Emergency Response team to discern future scenarios and their probabilities.
Our newsletter tracks the greatest ongoing threats and assigns probabilities to escalation events.
