What they did

Researchers at Microsoft Research and Carnegie Mellon University surveyed 319 knowledge workers, people whose jobs are mostly thinking work, about 936 real examples of using generative AI at work. For each example, people described how much critical thinking they did and how confident they felt, both in the AI and in themselves.

What they found

People who trusted the AI more reported doing less critical thinking on the task. People who were more confident in their own abilities reported doing more.

“Higher confidence in GenAI is associated with less critical thinking, while higher self-confidence is associated with more critical thinking.”

What it doesn't show

  • It is self-reported. People described their own thinking; nobody measured it directly.
  • It is correlational. It shows that trust in AI and less critical thinking go together, not that one causes the other.
  • It covers knowledge workers using AI at their jobs, not students.

How MindMargin relates

The study links self-confidence with more critical thinking. MindMargin is built to give you small, regular wins you earned yourself: a word you recalled, a card you got right before the AI finished. It is a small way to keep your own skills, and your trust in them, in use.

All four studies, and what they add up to
