## Summary

A new study reveals that automated interpretability scores for sparse-autoencoder features can be calculated without actually reading the explanations. Researchers found that over 90% of activating examples are cropped with the center token, and a simple rule based on this information achieves high accuracy. The study also shows that scoring rules can vary across different evaluation data pipelines, impacting their effectiveness. By analyzing these patterns, researchers have developed closed-form equations for what such rules can score, which could help improve automated interpretability methods.

## Key points

- 91.3% of activating examples are cropped with the center token
- A simple rule based on this information achieves balanced accuracy of 0.979
- Scoring rules vary across different evaluation data pipelines

## Why it matters

This research could help improve automated interpretability methods by providing insights into how scoring rules work and their effectiveness.
