Mechanistic interpretability methods lack statistical robustness, study finds

A new research paper argues that mechanistic interpretability (MI), a field focused on reverse-engineering AI models, suffers from fundamental instability. The authors contend that MI is essentially a statistical estimation problem, and current methods for identifying functional sub-networks within models are highly susceptible to variance. This means that small changes in data or hyperparameters can lead to significantly different interpretations of a model's internal workings, highlighting a need for more robust MI practices and stability metrics.
