Establish the validity of human-trust proxies

Establish whether the subjective and behavioral signals used by CRiDiT provide valid and reliable proxies for human trust perception when compared with objective measures of system trustworthiness.

Background

CRiDiT compares a machine-side estimate derived from objective performance and risk evidence with a human-side estimate derived from behavioral adoption decisions and subjective self-reports. The paper notes that these inputs differ in scope and evidential status.

Because the validity of the human-side proxies remains unresolved, an observed calibration gap may represent incompatibility between the measurement schemes rather than genuine misalignment between human trust and system trustworthiness.

References

System trustworthiness is evaluated through a wide range of performance and risk metrics, whereas human trust perception relies on a narrower set of signals whose validity as proxies remains open.
