Humans tend to either overuse or underuse robotic systems, particularly under high workload conditions, leading to potential negative outcomes. This human factors research insight is drawn from a 2018 study published in Studies in systems, decision and control. Using Literature review, researchers explored how this design variable affects real-world outcomes. The key design takeaway: Design robotic systems with mechanisms that actively guide users towards appropriate levels of trust and interaction, rather than assuming users will self-regulate effectively.
Over-reliance on robots increases risk, even for experienced users.

Key Findings
- 01Humans exhibit a tendency to either overuse or underuse robotic systems.
- 02High workload exacerbates the tendency for overuse of automation.
- 03This behavior is observed in both novice and experienced users.
- 04Robots are increasingly envisioned as teammates, adding complexity to trust dynamics.
Application
Design takeaway
Design robotic systems with mechanisms that actively guide users towards appropriate levels of trust and interaction, rather than assuming users will self-regulate effectively.
How to apply
When designing any system involving automation or robotics, anticipate potential user over- or under-reliance and build in features to mitigate these risks, such as explicit status indicators or advisory prompts.
Project actions
- 01When researching user interaction with a robot, specifically look for instances of over- or under-reliance.
- 02Consider how workload might affect user trust and interaction with your design.
Method & Evidence
Variables
Strengths & Limitations
Strengths
- +Highlights a critical, often overlooked, aspect of HRI: user trust dynamics.
- +Synthesizes existing knowledge to provide a broad overview of the problem.
Limitations
It can be difficult to accurately measure 'trust' in a user study; often, it's inferred from behavior.
Reliability & validity
The reliability of findings from a literature review depends on the quality and consistency of the studies reviewed. Validity is enhanced by the breadth of sources examined.
Think critically
How can designers proactively build systems that foster appropriate levels of trust, rather than leaving it to the user's potentially flawed judgment?
Design Principles
"Design for appropriate trust calibration: provide clear feedback and context to help users accurately assess system capabilities and limitations."
This tendency impacts the safe and effective integration of robots into various work environments. Designers must consider how to mitigate these trust-related pitfalls to ensure users interact with robotic systems appropriately, rather than with blind faith or complete skepticism.
What This Means for Your Design
People don't always use robots the right way – they might trust them too much or not enough, especially when they're busy. This can cause problems.

Paragraph starter
Research indicates that human interaction with robotic systems is often characterized by a tendency towards either over-reliance or under-reliance, particularly under conditions of high user workload. This phenomenon is not limited to novice users and poses significant challenges for the safe and effective deployment of robots, especially as they are increasingly designed to function as collaborative teammates.
