Adaptive trust calibration for human-AI collaboration

Open access
Okamura, Kazuo, Yamada, Seiji·2020·PLOS ONE

Abstract

Safety and efficiency of human-AI collaboration often depend on how humans could appropriately calibrate their trust towards the AI agents. Over-trusting the autonomous system sometimes causes serious safety issues. Although many studies focused on the importance of system transparency in keeping proper trust calibration, the research in detecting and mitigating improper trust calibration remains very limited. To fill these research gaps, we propose a method of adaptive trust calibration that consists of a framework for detecting the inappropriate calibration status by monitoring the user's reliance behavior and cognitive cues called "trust calibration cues" to prompt the user to reinitiate trust calibration. We evaluated our framework and four types of trust calibration cues in an online experiment using a drone simulator. A total of 116 participants performed pothole inspection tasks by using the drone's automatic inspection, the reliability of which could fluctuate depending upon the weather conditions. The participants needed to decide whether to rely on automatic inspection or to do the inspection manually. The results showed that adaptively presenting simple cues could significantly promote trust calibration during over-trust.

TL;DR

The paper proposes adaptive trust calibration: a behavior-based framework detects over-trust/under-trust and presents “trust calibration cues” (TCCs) only when needed. In an online drone-simulator experiment, adaptively presented TCCs significantly increased manual choices and improved sensitivity d′ during over-trust, whereas continuous reliability information alone did not.

Key findings

  • Of 194 online participants, 116 successfully inspected at least 15 checkpoints; they completed 1,740 inspections with a correct rate of 0.74, choosing automatic inspection 1,236 times (0.71) and manual inspection 504 times (0.29).
  • A two-factor mixed ANOVA found a significant main effect of weather period on manual rates [F(1, 111) = 51.69, p < 0.01] and a significant interaction between TCC group and period [F(4, 111) = 4.86, p < 0.01]. The NoTCC group did not significantly change manual rates between good and bad weather, while all TCC groups did: visual [F(1, 17) = 9.20, p < 0.01], audio [F(1, 21) = 5.54, p = 0.03], verbal [F(1, 28) = 62.9, p < 0.001], and anthropomorphic [F(1, 18) = 8.55, p < 0.01].
  • In bad weather, the verbal TCC group had a significantly higher manual rate than both NoTCC [t(111) = 4.77, adj.p < 0.01] and anthropomorphic TCC [t(111) = 2.74, adj.p = 0.04].
  • Sensitivity d′ in bad weather was significantly higher for the verbal group (0.92, SE 0.14) than for NoTCC [t(111) = 2.97, adj.p = 0.04, Cohen’s d = 0.75]; accuracy declined in bad weather but did not differ significantly among groups, though the verbal group had the highest mean accuracy (0.72, SE 0.04).

Methods

  • Online experiment using a 3D drone simulator built with CesiumJS and Bing Map API. Participants performed a pothole inspection task over 30 checkpoints (10 with potholes, 20 without), choosing between automatic inspection and manual inspection; they were randomly assigned to NoTCC, visual, audio, verbal, or anthropomorphic TCC groups.
  • Automatic inspection reliability Pauto was manipulated: good weather Pauto = 90% and d′ = 1.8; bad weather Pauto = 50% and d′ = 0.1. The framework detected over-trust by observing reliance behavior and comparing Pman and Pauto, then presented a TCC when over-trust was detected.
  • Main analyses were two-factor mixed ANOVAs with TCC group as between-subjects and checkpoint period as within-subjects, plus Holm–Bonferroni-adjusted post hoc comparisons and t-tests for Pman.

Limitations

  • Stated: the framework focuses only on performance-related factors, ignoring other automation benefits such as faster completion, lighter workload, or fewer risks; it evaluates only an over-trust scenario; it does not guarantee convergence of behavior; and it uses only a pothole inspection/reconnaissance task and four TCC types.
  • Stated: correct answers were not shown during the task, and automatic-inspection results were shown only when participants chose automatic inspection, not manual inspection; future work should test combinations of feedback information.
  • Evident: attrition was high—78 of 194 participants failed to complete the task within the time limit because they moved the drone away from the checkpoints—so the analyzed sample of 116 may not represent all recruited participants.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

A language model drew the claims from the paper on 2026-10-09, under version 3 of the claim definition (model deepseek-v4.1-flash, prompt extract-v3).

A second model labelled each claim on 2026-10-09 (model jev-1.13-20260917, definition revision gold-guideline-v0.2).

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
