Not All Trust is the Same: Effects of Decision Workflow and Explanations in Human-AI Decision Making
This study investigates the complex relationship between decision workflow (1-step vs. 2-step), AI explanations, and user characteristics on trust and reliance in AI-assisted decision making. We conducted an online study (N=300) in a fictional university student support scenario. Key findings indicate that self-reported trust and behavioral reliance are distinct constructs, only weakly correlated. Contrary to expectations, a 2-step setup increased overreliance. The effectiveness of explanations was context-dependent, boosting trust in a 2-step setup but lowering it in a 1-step setup. Domain knowledge also significantly influenced reported trust. These results highlight that trust in AI is not monolithic and its calibration requires careful consideration of workflow design and user context.

This study found only a weak correlation (r = .25) between self-reported trust (HCT questionnaire) and behavioral reliance (agreement rate or switch rate), indicating they are distinct constructs.
2-Step Decision Workflow Process
Contrary to previous suggestions, the 2-step decision setup significantly increased overreliance (accepting incorrect AI advice) compared to the 1-step setup (β = 0.46, p = .001), despite taking more time.
| Characteristic | 1-Step Workflow | 2-Step Workflow |
|---|---|---|
| AI Suggestion Timing | Immediate with Task | After User's Initial Decision |
| Reported Trust (with explanations) | Slightly Lower (M=3.09) | Higher (M=3.34) |
| Reported Trust (no explanations) | Slightly Higher (M=3.25) | Slightly Lower (M=3.20) |
| Overreliance Outcome | Lower | Significantly Higher |
| Avg. Time per Study | 13.8 minutes | 16.4 minutes |
| Switch Rate Measurable | No | Yes |
Explanations had a crossover interaction effect: they raised reported trust in a 2-step setup but lowered it in a 1-step setup. This suggests explanation impact is not universally positive and depends on the decision workflow.
University Student Support Task & User Characteristics
Scenario: Participants acted as student support officers, deciding the academic trajectory (graduate/dropout) of second-year university students based on provided data and AI predictions.
Key Findings:
- AI accuracy was 73%, matching human accuracy at 73%.
- Users with low domain knowledge reported significantly lower trust in the AI, though their behavioral reliance did not differ.
- Domain knowledge positively predicted reported trust (β = 0.24, p = .001).
- Interaction effects observed between workflow and domain knowledge on reported trust.
