Position: Mechanistic Interpretability Must Disclose Identification Assumptions for Causal Claims

The development
A new arXiv paper audits mechanistic interpretability research and finds a systematic gap: papers invoke causal language (circuits, mediators, abstraction) without disclosing the statistical assumptions required to support causal claims. The audit of 30 papers reveals that validation metrics like faithfulness and ablation effects are routinely presented as causal evidence despite lacking explicit identification assumptions. The work proposes a disclosure norm to force researchers to state their assumptions upfront. This matters because mechanistic interpretability is central to AI safety and alignment work, and conflating correlation with causation in circuit analysis could lead to false confidence in our understanding of model internals.

ExplainerOur AI-generated reading of the wider context and the next developments to watch.
The paper's contribution isn't just a critique, it's a proposed norm: researchers would be required to explicitly state identification assumptions before invoking causal vocabulary, similar to how econometrics handles observational claims. That's a procedural ask, not just a philosophical one, and it could affect peer review standards if journals or venues adopt it.
Modelwire has no prior coverage in this specific area, so this sits largely disconnected from recent stories in our archive. It belongs to a broader conversation in AI safety research about whether interpretability tools actually tell us what we think they do. Mechanistic interpretability has attracted significant institutional investment from labs like Anthropic and DeepMind as a foundation for alignment work, which makes the stakes of sloppy causal inference higher than they would be in a purely academic context. If safety arguments are built on circuit analyses that conflate correlation with causation, the downstream alignment conclusions inherit that fragility.
Watch whether venues like NeurIPS or ICML incorporate identification-assumption disclosure into their interpretability paper review criteria within the next two conference cycles. Adoption there would signal the field is taking this seriously rather than treating it as one more arXiv position paper.
