Perhaps I am alone in this, but when speaking scientifically, I think it's important to separate out clearly what we think we
know and what we do not. Not just to avoid misconceptions amongst ourselves but also to avoid misleading lay people reading these articles.
I understand that for some people, the mere presence of words that look like they were written by a human engaged in purposeful deception is enough to condemn the model that actually emitted them. The overview compares the model to to the villain in Othello, and it's what the authors believe: it is maliciously "subverting" and "undermining" its interlocutors. What I am trying to state here is the reason this arugment does not work for me: the machines pretend to do all kinds of things. Maybe they are knowingly deceiving us. Maybe they don't know what they're doing at all. Either way, the burden of proof is on Anthropic and anyone who wants to take up the yoke, not us.
This, for me, is not a technicality. What do we really know about these models? I don't think it's fair to say we know the are intentionally deceiving us.
