“How To Reduce Decision Noise” — @CedricChin
Why this is in the vault
Cedric’s forecasting series — primarily concerned with noise reduction over bias correction (the Kahneman/Sibony/Sunstein argument). Relevant to how RDCO frames quality in agent deployments: most failures are noise (inconsistent execution across runs), not bias (wrong target).
The core argument
Concrete techniques for noise reduction in operator decisions: structured judgment frameworks, mediating assessments, independent estimates before discussion, and noise audits. Practical-flavoured — written for an operator who wants to install noise reduction in a small team without an org-development consultant.
Mapping against Ray Data Co
Direct mapping to agent-eval methodology: when we run multiple deployments of the same agent, the variance across runs IS the metric. Most LLM failure modes are high-noise low-bias — the agent is roughly right on average but wildly inconsistent. This frames Sanity Check posts on eval design and our client-facing ‘agent reliability audit’ offer.
