Microsoft Researchers Find AI Affects Our Critical Thinking

A new study from Microsoft Research and Carnegie Mellon University reveals how AI tools are reshaping critical thinking in the workplace. While AI makes tasks easier, it may also be quietly eroding one of the most valuable skills we bring to our jobs: the ability to think critically.

Details:

  • The researchers sampled 319 knowledge workers across professions in computer science, education, entertainment/media, administration, and financial and business services. 

  • They found that the more people trust AI, the less likely they are to think critically about its outputs. However, workers confident in their own skills engage more critically with AI—even if it requires extra effort.

  • AI is changing critical thinking in three fundamental ways:

    • From gathering information to verifying it.

    • From solving problems to adapting AI solutions to specific needs.

    • From executing tasks to overseeing AI task completion.

  • Companies may need to create roles focused on AI oversight and provide workers with more opportunities to practice critical thinking, as automating routine cognitive tasks inadvertently reduces everyday opportunities to develop these skills.

AI isn’t replacing critical thinking—it’s changing how we apply it. To thrive in an AI-driven workplace, workers must balance trust in AI with thoughtful oversight. Success will belong to those who combine domain expertise with the ability to evaluate and refine AI outputs carefully.
