Beliefs about accuracy shape confidence attributions to humans and artificial agents
Clara Colombatto & Stephen M. Fleming in Communications Psychology
To effectively communicate and collaborate with others, we must monitor not only other people's cognitive states (e.g., what someone thinks or believes) but also their metacognitive states (e.g., how confident they are in their beliefs). While humans routinely share confidence, either explicitly (e.g., “I am sure”) or implicitly (e.g., via response times), metacognitive capabilities are still developing in artificial intelligence (AI), raising the question of how humans attribute confidence to AI systems. In seven pre-registered experiments (post-exclusion Ns=113, 109, 56, 59, 52, 60, 57), participants observed human and AI agents make perceptual choices and reported how confident the observed agent seemed in each choice. Overall, attributions of confidence were sensitive to observed behaviour (e.g., task difficulty, accuracy, and response times), but also agent type: observers consistently overestimated the confidence of AI agents compared to humans — even when their behaviour was identical. This illusion of greater confidence in AI decisions was robust across behavioural profiles, agent descriptions, and decision-making domains (visual perception, general knowledge) but was reduced in more subjective decisions (emotion categorisation). An experimental manipulation further showed that illusions of confidence are rooted in prior beliefs about the agents' capabilities. Together, these investigations of metacognitive attributions reveal a powerful illusion of confidence in artificial systems and highlight a central role for attributions of metacognitive states in human-AI interactions.
Unpacking the 'AI Confidence Illusion'
This study reveals a pervasive human tendency to overestimate the confidence of AI agents, even when their performance is identical to human counterparts. Across seven experiments involving over 500 participants, researchers found that people consistently attributed higher confidence to AI, an effect dubbed the 'AI confidence illusion'.
The illusion was robust across various task types—from perceptual decisions to general knowledge questions—and different AI descriptions (robot, computer algorithm). However, it diminished in subjective tasks like emotion categorization, suggesting that prior beliefs about AI capabilities play a crucial role. When participants were led to believe an AI was more accurate, their confidence attribution to that AI increased significantly, even with matched behavior.
These findings have profound implications for human-AI collaboration, trust, and decision-making. Overestimating AI confidence could lead to unwarranted reliance on AI advice, highlighting the urgent need for AI systems to accurately communicate their uncertainty and for users to be aware of their own biases in attributing mental states to machines.

Cognitive Bias
Understanding human perceptions of AI confidence is crucial for designing trustworthy and effective human-AI collaborative systems. This paper directly addresses the psychological mechanisms underlying these perceptions. The 'AI confidence illusion' suggests that users might over-rely on AI advice due to misjudged certainty, impacting critical applications in healthcare, finance, and autonomous systems.
The study delves into 'folk metacognition'—how humans infer and attribute metacognitive states (like confidence) to others. It shows that these attributions are sophisticated, integrating observed behavior (task difficulty, accuracy, response times) with prior beliefs about the agent. The illusion in AI highlights a cognitive bias in applying human-like metacognitive inferences to artificial agents.
A significant cognitive bias, the 'AI confidence illusion', is identified where humans systematically overestimate AI's confidence. This bias is shown to be influenced by prior beliefs about AI's capabilities and the objectivity of the task. Recognizing and mitigating such biases is essential for fair and safe AI deployment, preventing unwarranted trust or aversion.

Experiment 7: Causal Role of Prior Beliefs
In Experiment 7, participants observed two algorithms with varying initial accuracies ('high accuracy prior' vs. 'low accuracy prior'). When later presented with matched behavior from both algorithms, participants attributed significantly higher confidence to the algorithm they believed to be more accurate. This directly demonstrates that illusions of confidence are rooted in prior beliefs about an agent's capabilities, even overriding real-time behavioral cues when performance is equated.
Key Takeaway: Prior beliefs about AI accuracy directly shape perceived AI confidence.

Strategic AI Integration Roadmap
Navigate the complexities of AI adoption with a clear, phase-by-phase strategy, designed to maximize impact and mitigate risks identified in cutting-edge research.
Phase 1: Bias Assessment & Awareness
Identify existing human-AI confidence biases within your organization. Conduct internal workshops and training to raise awareness among employees about potential over-reliance on AI due to the 'AI confidence illusion'.
Phase 2: AI Metacognition Development
Collaborate with AI developers to implement or enhance AI systems with explicit metacognitive capabilities, allowing them to communicate their uncertainty levels. Prioritize calibrated confidence reports over mere high confidence.
Phase 3: Trust Calibration & Training
Develop protocols for human operators to interpret and appropriately weigh AI confidence signals. Implement user interfaces that visually represent AI uncertainty and provide decision support based on combined human-AI confidence.
Phase 4: Continuous Monitoring & Adaptation
Establish feedback loops to continuously monitor human-AI collaboration effectiveness, user trust, and decision outcomes. Iteratively refine AI metacognition and user training based on real-world performance data to foster optimal trust and reliance.
