Good quality. Reputable source with community review or editorial standards, but less rigorous than peer-reviewed venues.

Rating inherited from publication venue: Alignment Forum

A critical editorial by Stephen Casper (scasper) assessing Anthropic's 2024 scaling monosemanticity SAE paper; notable for articulating the 'safety washing' concern about high-profile interpretability research that lacks concrete safety applications.

Importance: 58/100blog postcommentary

Summary

Stephen Casper evaluates Anthropic's May 2024 sparse autoencoder (SAE) paper against 10 prior predictions, concluding the paper accomplished only predictions 1-3 while falling short on 4-10. He argues Anthropic's interpretability research may be better characterized as 'safety washing' than practical safety work, as it demonstrates capability without solving concrete safety problems.

Key Points

  • •Author scored Anthropic's SAE paper -0.74 against his predictions, indicating systematic underperformance relative to expected safety-relevant outputs.
  • •Paper found 'safety-relevant features' but failed to competitively identify and remove harmful behaviors actually represented in training data.
  • •Raises concern that high-profile mechanistic interpretability research prioritizes demonstrating technical elegance over solving actionable safety problems.
  • •Part of the 'Engineer's Interpretability Sequence,' a recurring critical examination of interpretability research from a practical safety standpoint.
  • •Distinguishes between proofs-of-concept for useful tasks (achieved) and real-world deployment of interpretability for harm mitigation (not achieved).

# TL;DR

On May 5, 2024, [I made a set of 10 predictions](https://x.com/StephenLCasper/status/1787270794017702045) about what the next sparse autoencoder (SAE) paper from Anthropic would and wouldn’t do. [Today’s new SAE paper from Anthropic](https://transformer-circuits.pub/2024/scaling-monosemanticity/index.html) was full of brilliant experiments and interesting insights, but it underperformed my expectations. I am beginning to be concerned that Anthropic’s recent approach to interpretability research might be better explained by safety washing than practical safety work.

Think of this post as a curt editorial instead of a technical piece. I hope to revisit my predictions and this post in light of future updates.

# Reflecting on predictions

[See my original post](https://x.com/StephenLCasper/status/1787270794017702045) for 10 specific predictions about what [today’s paper](https://transformer-circuits.pub/2024/scaling-monosemanticity/index.html) would and wouldn’t accomplish. I think that Anthropic obviously did 1 and 2 and obviously did not do 4, 5, 7, 8, 9, and 10. Meanwhile, I think that their experiments to identify [specific](https://transformer-circuits.pub/2024/scaling-monosemanticity/index.html#searching) and [safety-relevant](https://transformer-circuits.pub/2024/scaling-monosemanticity/index.html#safety-relevant) features should count f
