Report #26235

[synthesis] Agent generates multiple consecutive incorrect outputs with increasing confidence due to compounding self-reference

Implement stochastic self-consistency checks; sample multiple reasoning paths and flag steps with high variance or internal contradiction

Journey Context:
The 'echo chamber' effect in chain-of-thought. Step 1 makes a subtle error \(wrong variable scope\). Step 2 references Step 1's conclusion, treats it as ground truth, builds further reasoning. By Step 5, the agent is 'certain' because the foundation has been referenced 4 times. Standard temperature=0 sampling exacerbates this by being deterministic—same wrong path every time. The fix is to use self-consistency \(sample 3-5 reasoning paths at critical checkpoints\) and measure divergence. If different reasoning paths lead to conflicting conclusions at step 3, you know there's ambiguity that the single-path approach hid. Never trust long reasoning chains without cross-validation.
