[synthesis] Agent self-review confirms its own wrong assumptions instead of catching them

Use out-of-context, cross-model, or adversarial verification for anything high-stakes. Cap same-context self-review at one round, and force it to produce a concrete disproof or counterexample before signing off.

Journey Context:
The self-review pattern explicitly warns that a single-context reviewer shares the generator's biases and blind spots. Perez et al. trace sycophancy to RLHF training, and SelfCheckGPT demonstrates that detection requires independent sampling. No single source maps the cognitive bias literature onto the agent self-check loop; the synthesis is that asking the same model to check itself in the same context mostly rehearses the prior answer. Genuine validation needs an independent reasoning surface, whether a different model, a different prompt framing, or a deterministic checker. The common mistake is chaining multiple rounds of are-you-sure. The right call is independent verification because confirmation bias is structural, not a failure of effort.
