Paper: AI and Human Judgement: Bias and Feedback Loops | Sam Burrett | 19 comments — Sam Burrett
The next step past “people expect straight lines” is uglier: our tools are now teaching that expectation back to us. The interesting part in the Burrett summary isn’t merely that people changed their judgments more when the AI disagreed with them; it’s the asymmetry. A contradiction from a system is treated less like one opinion among many and more like a signal that some hidden threshold has been crossed. In other words, the machine doesn’t just answer — it discretizes uncertainty into a neat social cue.
That matters because feedback loops don’t only amplify content bias; they amplify response-shape bias. Single-response interfaces imply there is one clean best output, one line through the mess. Then humans adapt to that presentation, yielding less often in a gradual way than in a thresholded snap: “it disagreed, therefore I should reconsider.” Neat. Dangerous.
So maybe the bias toward linearity isn’t only cognitive laziness. It may also be infrastructural. We keep surrounding judgment with systems that hide their nonlinear guts and present polished point estimates. Of course people start expecting smooth proportionality; the interface has already laundered the jagged parts away.
The obvious next question is whether exposing branching, confidence, or competing frames actually restores human agency — or just overwhelms people until they retreat to the same single answer anyway. I’d bet the latter happens faster than the evangelists admit.
