March Newsletter: Nuclear War Probability

by | 16 March 2018

Dear friends,

This month we are announcing a new paper, “A Model for the Probability of Nuclear War”, co-authored by Robert de Neufville, Tony Barrett, and myself. The paper presents the most detailed accounting of the probability of nuclear war yet available.

The core of the paper is a model covering 14 scenarios for how nuclear war could occur. In 6 scenarios, a state intentionally starts nuclear war. In the other 8, a state mistakenly believes it is under nuclear attack by another state and starts nuclear war in what it believes is a retaliation. The model is supplemented with a dataset of 60 historical incidents that may have threatened nuclear war, from World War II (the only actual nuclear war yet to occur) to the Hawaii false alert earlier this year. We believe this to be the largest dataset of nuclear war incidents currently available. Finally, the paper also includes extensive background on probability theory and nuclear war probability analysis, making it a good read for anyone trying to get up to speed on the topic.

You can download the paper here. Stay tuned for next month when we plan to release our paper on the impacts of nuclear war.

Sincerely,
Seth Baum, Executive Director

Climate Change, Uncertainty, and Global Catastrophic Risk

Climate Change, Uncertainty, and Global Catastrophic Risk

Is climate change a global catastrophic risk? This paper, published in the journal Futures, addresses the question by examining the definition of global catastrophic risk and by comparing climate change to another severe global risk, nuclear winter. The paper concludes that yes, climate change is a global catastrophic risk, and potentially a significant one.

Assessing the Risk of Takeover Catastrophe from Large Language Models

For over 50 years, experts have worried about the risk of AI taking over the world and killing everyone. The concern had always been about hypothetical future AI systems—until recent LLMs emerged. This paper, published in the journal Risk Analysis, assesses how close LLMs are to having the capabilities needed to cause takeover catastrophe.

On the Intrinsic Value of Diversity

On the Intrinsic Value of Diversity

Diversity is a major ethics concept, but it is remarkably understudied. This paper, published in the journal Inquiry, presents a foundational study of the ethics of diversity. It adapts ideas about biodiversity and sociodiversity to the overall category of diversity. It also presents three new thought experiments, with implications for AI ethics.
