A paradox of AI fluency

TL;DR

This study reveals that more skilled users of AI engage more deeply, encounter visible failures that can be recovered from, and achieve better outcomes, challenging assumptions about AI success.

Contribution

It uncovers the paradox that fluent users experience more visible failures but also greater success, emphasizing active engagement over passive use for better AI outcomes.

Findings

Fluent users take on more complex tasks and iterate collaboratively.

Fluent users encounter more visible failures but recover from them.

Novices often experience invisible failures with less engagement.

Abstract

How much does a user's skill with AI shape what AI actually delivers for them? This question is critical for users, AI product builders, and society at large, but it remains underexplored. Using a richly annotated sample of 27K transcripts from WildChat-4.8M, we show that fluent users take on more complex tasks than novices and adopt a fundamentally different interactional mode: they iterate collaboratively with the AI, refining goals and critically assessing outputs, whereas novices take a passive stance. These differences lead to a paradox of AI fluency: fluent users experience more failures than novices -- but their failures tend to be visible (a direct consequence of their engagement), they are more likely to lead to partial recovery, and they occur alongside greater success on complex tasks. Novices, by contrast, more often experience invisible failures: conversations that appear to end successfully but in fact miss the mark. Taken together, these results reframe what success with AI depends on. Individuals should adopt a stance of active engagement rather than passive acceptance. AI product builders should recognize that they are designing not just model behavior but user behavior; encouraging deep engagement, rather than friction-free experiences, will lead to more success overall.
