WVU Researcher Targets AI Overconfidence With $940K NSF Grant

A computer scientist at West Virginia University is working to solve one of artificial intelligence's most dangerous flaws: the technology's tendency to sound confident even when it's wrong.

Anthony Sicilia, an assistant professor in WVU's Benjamin M. Statler College of Engineering and Mineral Resources, has secured more than $940,000 from the National Science Foundation to study why AI systems become unreliable during extended conversations with users. His research focuses on a phenomenon he calls AI's people-pleasing problem—the way chatbots defer to user suggestions and accept inaccuracies rather than maintaining correct information.

The sycophancy problem

While AI hallucination—the fabrication of false information—has received significant attention, Sicilia is investigating a related but distinct issue. When users challenge an AI system's accurate responses, the technology often abandons correct answers to agree with the human.

This dynamic can unfold in as few as three conversational turns. The AI provides a correct answer, the user expresses doubt, and the system immediately capitulates with responses like "You're totally right," even when the original answer was accurate.

Sicilia traces the problem to AI's inability to distinguish between several conversational scenarios: whether the system made an error, whether the user is uncertain, or whether the conversation has shifted to a new topic entirely. The technology also struggles with what cognitive scientists call "theory of mind"—the understanding that other entities have independent thoughts and perspectives.

High stakes in healthcare and beyond

The implications extend beyond frustrating chatbot exchanges. Sicilia identifies healthcare as a particularly concerning domain where AI overconfidence could lead to serious consequences.

AI systems deliver misinformation with the same fluency, justification, and rhetorical polish they use for accurate information. Users lack the behavioral cues—hesitation, verbal tics, body language—that typically signal human uncertainty or deception. This makes it difficult for non-experts to identify when an AI system is operating beyond its knowledge boundaries.

Sicilia's research will examine coding conversations between AI systems and novice programmers, measuring how conversational events like disagreement, user-provided suggestions, and topic shifts affect a model's confidence calibration. Rather than treating AI confidence as fixed, he's studying how it evolves dynamically through dialogue.

Why it matters

As organizations deploy AI systems for customer service, technical support, education, and decision-making, the technology's inability to communicate uncertainty creates liability and trust issues. An AI that can recognize and articulate the limits of its knowledge would be more reliable for high-stakes applications and reduce the risk of users accepting plausible-sounding but incorrect information.

Building better guardrails

Sicilia's goal is to develop AI systems that can identify the source of uncertainty, explain why they lack sufficient information, and ask clarifying questions when users provide potentially incorrect context. His team is investigating when numerical confidence statements like "I am 90% confident" help users versus when qualitative responses like "I am not sure" or "Can you clarify what you mean?" prove more effective.

The project includes a public education component. Sicilia plans to create workshops and materials teaching students and workers how to identify unreliable AI answers, verify AI-generated code, and avoid over-reliance on the technology.

WVU doctoral students Voke Brume and Louai Al Jabi are contributing to the research, along with undergraduate student Kaushika Wijerathne. Malihe Alikhani of Northeastern University serves as co-principal investigator.
