Subclaims

Reading the evidence codes

q is the design tier, i the impact, n the sample, and the kind with its r the rigour judged within that kind: what each code means.

This claim: no standardized effect is recorded in observations/ for it yet, so no benchmark reading is possible.

q2 i? Per HCI research the article draws on, users change their expectations and behaviors according to perceived AI capabilities even when underlying AI performance stays the same. → Tomohiro Nagashima 2026

Evidence

Tomohiro Nagashima 2026

Tomohiro Nagashima, Mirella Hladký, and Vera Rief. (2026). Warning About AI Fallibility Increases Help-Seeking in an Intelligent Tutoring System. https://arxiv.org/abs/2606.03822 doi:10.48550/arxiv.2606.03822

q2 · i? · causal · r2

The article cites HCI research on the "placebo effect" of AI as the rationale for keeping system behavior identical across conditions; the review-level assertion is attributed to that cited work rather than tested here, so it is reported as the article attributes it.

"This phenomenon demonstrates that users alter their expectations and behaviors based on perceived capabilities of AI, even when the underlying AI performance remains the same [6]."
