# Verification is easier than generation for AI alignment at current capability levels but the asymmetry narrows as capability gaps grow creating a window of alignment opportunity that closes with scaling

Paul Christiano's entire alignment research program — debate, iterated amplification, recursive reward modeling — rests on one foundational asymmetry: it is easier to check work than to do it. This asymmetry is what makes delegation safe in principle. If a human can verify an AI system's outputs even when the human couldn't produce those outputs, then progressively delegating harder tasks to AI while maintaining oversight is a viable alignment strategy.

The intuition has strong everyday support. Reviewing a paper is easier than writing it. Verifying a mathematical proof is easier than discovering it. Checking code for bugs is easier than writing correct code. Computationally, this maps to the P ≠ NP conjecture — the class of efficiently verifiable problems is widely believed to be strictly larger than the class of efficiently solvable problems. Christiano's debate framework extends this: with two adversarial AI systems and a human judge, the verifiable class expands from NP to PSPACE — an exponential amplification of human judgment capacity.

The empirical evidence supports the asymmetry at current capability levels but reveals it narrowing with scale. The 2025 Scaling Laws for Scalable Oversight paper quantifies this: at an Elo gap of 400 between overseer and system, debate achieves 51.7% success — degraded but not collapsed. At smaller gaps, success rates are higher. At larger gaps, they decline further. The asymmetry exists as a continuous function of capability gap, not as a binary that holds or fails.

This creates what might be called a **window of alignment opportunity**: the period during which AI systems are capable enough to be useful but not so capable that verification breaks down. Within this window, prosaic alignment techniques (RLHF, debate, amplification) can make genuine progress. Beyond it, Yudkowsky's concern applies — [[verification being easier than generation may not hold for superhuman AI outputs because the verifier must understand the solution space which requires near-generator capability]].

The critical question is how wide this window is. Christiano's bet: wide enough that iterative alignment progress within the window carries forward to higher capability levels. Yudkowsky's counter: the window closes precisely when it matters most, creating false confidence during the period when alignment appears tractable.

## Practical Implications

The window framing resolves a binary debate into a quantitative question. Rather than asking "does verification asymmetry hold?" the productive question is "at what capability gap does verification success drop below safety-relevant thresholds, and how fast are we approaching that gap?" The NLAH finding that [[verifier-level acceptance can diverge from benchmark acceptance even when locally correct because intermediate checking layers optimize for their own success criteria not the final evaluators]] provides a mechanism for how verification degrades — through accumulated drift in intermediate checking layers, not through sudden collapse. This favors Christiano's continuous model over Yudkowsky's discontinuous one, but the degradation is still real and safety-relevant.

Relevant Notes:
- [[verification being easier than generation may not hold for superhuman AI outputs because the verifier must understand the solution space which requires near-generator capability]] — Yudkowsky's direct counter-claim: the asymmetry breaks at superhuman scale
- [[scalable oversight degrades rapidly as capability gaps grow with debate achieving only 50 percent success at moderate gaps]] — empirical evidence for narrowing asymmetry
- [[verifier-level acceptance can diverge from benchmark acceptance even when locally correct because intermediate checking layers optimize for their own success criteria not the final evaluators]] — mechanism for how verification degrades
- [[human verification bandwidth is the binding constraint on AGI economic impact not intelligence itself because the marginal cost of AI execution falls to zero while the capacity to validate audit and underwrite responsibility remains finite]] — verification as economic bottleneck
