Release Date: May 30, 2025
Host: Kevin Frazier
Guest: Josh Batson, Research Scientist at Anthropic

Introduction

In this episode of The Lawfare Podcast, host Kevin Frazier engages in a comprehensive discussion with Josh Batson, a research scientist at Anthropic, focusing on the intricate workings of Artificial Intelligence (AI) models. The conversation delves into the concepts of AI interpretability and explainability, exploring how understanding these elements is crucial as AI becomes increasingly integrated into sensitive decision-making processes such as hiring, admissions, and medical diagnoses.

AI as a Black Box

Timestamp [03:11]
Josh Batson begins by addressing the prevalent notion of AI as a "black box." Unlike traditional software, where every line of code is transparent and understandable, AI models operate through complex neural networks that resemble biological systems. Batson analogizes AI models to trained horses—predictable to an extent but not entirely comprehensible in their decision-making processes.

“AI models aren't like that. They're almost like biological systems... And in the same way that you can train a horse or something, the horse is something of a black box.”
— Josh Batson [03:11]

Interpretability vs. Explainability

Timestamp [04:38]
The discussion distinguishes between interpretability and explainability:

• Interpretability involves understanding the step-by-step mechanisms of how an AI model processes information and arrives at decisions.
• Explainability, on the other hand, refers to providing explanations that make sense to humans, which may not delve into the mechanistic details.

Batson uses the example of a sports commentator explaining a missed shot by Serena Williams, which provides a plausible but not mechanistic explanation, contrasting it with a detailed biomechanical analysis.

“Explainability is... an account that makes sense to you... whereas interpretability, I think we prioritize things that are almost like mechanistically correct.”
— Josh Batson [05:00]

Importance of Understanding AI Strategies

Timestamp [07:14]
Batson emphasizes the necessity of understanding AI models beyond treating them as black boxes. This understanding allows stakeholders to:

1. Predict Performance: Knowing the strengths and limitations of AI models helps in anticipating how they perform in various scenarios.
2. Enhance Safety: Understanding the internal mechanisms aids in making AI systems safer and more reliable.
3. Improve Models: Insights into AI strategies can lead to the development of more advanced and efficient models.

He draws parallels with biomedicine, where understanding the active compounds in aspirin has led to broader medical advancements.

Recent Research and Case Studies

1. Poetry Generation Case Study

Timestamp [15:32]
Batson discusses a study where AI was tasked with writing a rhyming couplet. The model demonstrated forward planning by considering possible rhyming words early in the generation process, rather than deciding solely at the end.

“The model... was thinking about a place to go. And... it was thinking about a few options... influences the direction of the whole next line.”
— Josh Batson [16:47]

This finding challenges the "stochastic parrot" theory, suggesting that AI models possess emergent planning capabilities.

2. Mathematics Case Study

Timestamp [20:36]
In exploring how AI handles mathematical calculations, Batson reveals that models employ unconventional methods, integrating parallel processing pathways instead of traditional step-by-step calculations taught in schools.

“It was looking at the rough size, you know, ballparking it, right?... And so it had learned during training another way of doing addition.”
— Josh Batson [21:20]

This approach highlights AI's ability to develop unique problem-solving strategies that diverge from human methodologies.

3. CBRN Risks and AI Safety

Timestamp [30:08]
Addressing concerns about AI being used to develop chemical, biological, radiological, and nuclear (CBRN) weapons, Batson explains Anthropic's efforts to identify and prevent such misuse. The discussion covers "jailbreaks," where users manipulate prompts to elicit harmful responses from AI models.

“We could see that it didn't even know it was going to say bomb until the word came out of its mouth.”
— Josh Batson [31:16]

This case study underscores the challenges in ensuring AI systems adhere to safety protocols even under coercive attempts.

Implications for Policy and Decision-Making

Timestamp [37:07]
Frazier and Batson explore the integration of AI into judicial systems, comparing AI judges to human judges. They discuss the potential benefits of AI in providing consistent and unbiased rulings, while also addressing concerns about the lack of transparent reasoning behind AI decisions.

“We should be holding humans to at least the standard of what the AIs can do in terms of the quality of their written opinions.”
— Josh Batson [42:10]

Batson suggests a dual-model approach, where one model generates rulings and another reviews them, enhancing accountability and reducing biases.

Current State and Future of AI Interpretability

Timestamp [44:13]
Batson provides an overview of the progress in AI interpretability, likening the field to being in "elementary school" with substantial advancements being made rapidly. He anticipates significant breakthroughs in understanding AI mechanisms within the next few years, driven by continuous research and the development of new tools.

“We can expect to have much better accountings of this, you know, another year or two, right, we'll have some traction.”
— Josh Batson [45:06]

Batson acknowledges that while complete interpretability is unattainable—comparable to solving biology or law—the strides made thus far offer promising avenues for deeper understanding.

Conclusion

The episode concludes with Batson emphasizing the critical role of interpretability and explainability in fostering public trust and facilitating the responsible adoption of AI technologies in decision-making processes. Frazier underscores the importance of these advancements in informing policy and ensuring AI systems are transparent and accountable.

“With better interpretability and explainability, that's only going to accelerate adoption.”
— Kevin Frazier [46:23]

Batson commits to continuing his research, highlighting the ongoing effort required to unravel the complexities of AI models.

Key Takeaways

• AI as a Black Box: Unlike traditional software, AI models operate through complex, less transparent neural networks, making their decision-making processes harder to decipher.

• Interpretability vs. Explainability: Understanding AI requires both mechanistic insights (interpretability) and user-friendly explanations (explainability).

• Emergent Capabilities: AI models demonstrate unexpected strategies, such as forward planning in poetry generation and unconventional problem-solving in mathematics.

• Safety and Misuse Prevention: Continuous efforts are needed to safeguard AI systems from being manipulated for harmful purposes, such as developing weapons.

• Policy Implications: Integrating AI into sensitive areas like the judiciary necessitates robust interpretability to ensure fairness, consistency, and accountability.

• Ongoing Research: The field of AI interpretability is rapidly evolving, with significant progress anticipated in the near future to enhance our understanding of AI mechanisms.

This episode offers a deep dive into the complexities of AI interpretability, highlighting both the advancements made and the challenges that lie ahead. For policymakers, technologists, and the general public, understanding these dynamics is essential as AI continues to shape various facets of society.
