[synthesis] Agent's confidence increases with each step in a wrong reasoning chain, making the most dangerous states the ones where the agent is most certain

Decouple confidence from reasoning chain length. Implement a confidence calibration rule: confidence must decrease monotonically with the number of steps since the last external validation. Never allow an agent to report high confidence on a long chain without independent verification checkpoints.

Journey Context:
LLM confidence correlates with the coherence and length of the reasoning chain, not with correctness. A long chain of wrong-but-internally-consistent steps produces higher expressed confidence than a short chain with a correct but uncertain conclusion. This is because the model's confidence mechanism is essentially 'does this follow from what came before,' not 'is this actually true.' The compounding effect: each step in a wrong chain makes the next step feel more supported, which makes the agent more confident, which makes it less likely to question its assumptions. By the time the agent reaches a catastrophic decision, it may report 95% confidence. This inverts the safety assumption that high-confidence outputs are more reliable. The synthesis requires holding LLM calibration research alongside agent orchestration patterns: no single source identifies this inversion because calibration research studies single-turn Q&A while agent research assumes confidence is a useful signal. The fix—confidence decay without external validation—breaks the compounding loop by making the agent's own confidence a signal that verification is overdue, not that the answer is correct.
