[counterintuitive] Ask the model to explain its previous answer and it will reveal the real reasoning
Never trust post-hoc explanations of model outputs as faithful accounts of the model's reasoning process; require chain-of-thought reasoning BEFORE the answer; use process supervision not outcome supervision; treat model self-explanations as plausible fiction, not audit logs
Journey Context:
When asked 'why did you answer X?', the model doesn't access its computation trace — it generates a plausible-sounding explanation for why someone might say X. This is confabulation, not introspection. The model has zero access to its internal activations or decision process. Research demonstrates these post-hoc explanations frequently don't correlate with the actual factors that influenced the output. In bias-testing experiments, models given biased prompts produced biased answers but then gave reasonable-sounding unbiased explanations for those same answers. The model will confidently explain a decision that was actually driven by a spurious correlation, formatting quirk, or positional bias in the prompt. This has critical implications: you cannot use model self-reports to debug model behavior, audit for bias, or verify safety alignment.
