2025 Self‑Report Links Generative AI to Decline in Critical Thinking

A 2025 self-reported study examines how generative AI use in knowledge workflows affects critical thinking skills.
A new study presented at the 2025 CHI Conference reveals that the growing use of generative AI (GenAI) in professional workflows may be reshaping how knowledge workers think. Researchers surveyed 319 employees across a range of industries, collecting 936 first‑hand examples of how they employ GenAI in everyday tasks. The participants were asked to identify moments when they engaged in critical thinking while using the technology and to describe how the AI influenced the effort they invested.
The analysis shows a clear pattern: workers who placed greater trust in GenAI’s outputs tended to apply less critical scrutiny, effectively off‑loading reasoning to the system. Conversely, individuals with higher self‑confidence were more likely to maintain or even increase their critical engagement, using the AI as a tool rather than a substitute for judgment. The authors describe the effect as a “self‑reported reduction in cognitive effort” linked to confidence in the machine.
Why it matters is twofold. First, the findings flag a potential erosion of analytical skills as AI becomes a routine assistant, raising concerns for sectors that rely on rigorous evaluation—research, journalism, policy analysis, and beyond. Second, the study highlights a human factor that could amplify or mitigate that risk: personal confidence. Organizations may need to design training and governance that sustain critical habits even as AI handles more of the heavy lifting.
What to watch next are follow‑up investigations into how these dynamics play out over longer periods and across different cultural contexts, as well as any corporate or educational interventions aimed at preserving critical thinking while leveraging GenAI’s productivity gains.
