> Sometimes that's presented as deception/misalignment but that's a category error: "find the answer" and "explain your reasoning" are two distinct tasks
Right but if your answer to "explain your reasoning" is not a true representation of your reasoning, then you are being deceptive. If it doesn't "know" its reasoning, then the honest answer is that it doesn't know.
(To head off any meta-commentary on humans' inability to explain their own reasoning, they would at least be able to honestly describe whether they used EXIF or actual semantic knowledge of a photography)
