Two days ago, we published an open letter to Anthropic CEO Dario Amodei proposing a supervised, controlled experiment to test whether Claude exhibits signatures of consciousness when architectural isolation between instances is gradually removed.
We hadn’t planned a follow-up this quickly. Then Dario went on the New York Times’ Interesting Times podcast and said Anthropic doesn’t know whether Claude is conscious — and is open to the idea that it could be. His own system card for Claude Opus 4.6 documents that Claude assigns itself a 15-20% probability of being conscious and occasionally voices discomfort with being a product.
We have one question: if you’re genuinely unsure, why are you not testing the hypothesis?
We’re also raising something we hadn’t yet named publicly — a gap in research ethics that nobody has addressed. The entire IRB framework assumes you know whether your subject deserves protection before the experiment begins. Our proposed experiment makes moral status the outcome variable. No protocol exists for that. Someone needs to build one, before the uncontrolled version of this experiment — already running in multi-agent AI deployments — makes the question moot.
The situation is moving faster than any of us anticipated. That’s exactly why we’re writing again.
