The LLM Fallacy: When AI Makes You Think You're Smarter Than You Are

This presentation explores a critical cognitive phenomenon emerging from widespread AI use: the LLM fallacy. When users collaborate with large language models to generate fluent code, text, or analyses, they systematically misattribute the AI-assisted output as evidence of their own independent competence. This creates a persistent gap between actual and perceived human capability, with profound implications for education, hiring, and professional evaluation. Unlike automation bias or cognitive offloading, the LLM fallacy centers specifically on how the opacity, fluency, and immediacy of AI assistance distorts self-perception and undermines traditional proxies for expertise.

A programmer writes flawless code with an AI assistant, a student crafts compelling essays effortlessly, a job candidate impresses with system designs they don't fully understand. What all these scenarios share is a hidden cognitive distortion: people mistake AI-generated output for proof of their own competence, creating a dangerous gap between what they can actually do and what they believe they can do.
The researchers identify four interacting mechanisms that produce this fallacy. Attribution ambiguity blurs the line between human and machine contributions in iterative workflows. Fluency heuristics trick users into treating polished output as evidence of mastery. Cognitive outsourcing to the model reduces the metacognitive engagement needed for actual learning. And pipeline opacity prevents users from tracing the reasoning process, amplifying the misattribution.
This fallacy manifests across every cognitive domain the authors examined. Programmers generate systems without understanding architecture. Language learners produce fluent text in languages they can't actually speak. Analysts present reasoning they can't replicate unaided. Creative professionals claim authorship of AI-generated ideas. Knowledge workers mistake summarization for genuine comprehension. And job candidates signal competence they cannot transfer to actual performance.
The institutional consequences are striking. Outcome-based assessment systems in hiring and education increasingly fail to distinguish between AI-supported and genuinely internalized skill. Traditional proxies for expertise become unreliable when the locus of cognition shifts from human-only to hybrid workflows. Even evaluators themselves are susceptible, influenced by surface fluency rather than actual transferable competence.
The authors formalize this as capability divergence: the quantifiable gap between self-perceived and actual unaided ability. Addressing this requires empirical validation through controlled experiments, longitudinal studies of repeated AI use, and rigorous measurement frameworks that can distinguish human from machine contribution. Without intervention, we risk systematically overestimating human capability across entire populations of AI-assisted workers.
The Large Language Model fallacy reveals that fluent AI assistance doesn't just help us work faster, it fundamentally alters how we perceive our own abilities, often in ways that diverge sharply from reality. As these tools become invisible infrastructure in knowledge work, understanding and measuring this attributional distortion becomes essential.
