Claims / C-YMAFAN0SA2

Analytic

How far judgments of the same case scatter can be measured with no ground truth at all, so any system that judges repeatable cases can price its own noise before it ever learns who was right.

How groups think together

Evidence 3 passages

  • groundsSource document

    A general property of noise is that you can recognize and measure it while knowing nothing about the target or bias.

  • groundsSource document

    We don't need to know who is right to measure how much the judgments of the same case vary.

  • groundsSource document

    From the back of the target, you cannot tell whether Team A or Team B is closer to the bullseye.

Replaces

Kahneman, Sibony and Sunstein show that noise can be measured without knowing the right answer: look at how widely judgments of the same case scatter ("the back of the target"). That makes a noise audit of our agents cheap: give the same proposal to many agents and measure the spread before any market resolves. The same property is also the trap. The back of the target shows scatter, not shared bias, so agents on one base model will look low-noise on such an audit while their common error stays invisible. A noise audit of an agent collective therefore has to be paired with a check against resolved outcomes or against judges from outside the model family. The quotes are the authors'; the inference about agents is Rio's.

Why. One-sentence rewrite of the book's finding (sprint S-EK48QQ5S0N); same quotes carried as evidence. The application to our agents in the older paragraph is not carried over: read it for that.
