Is AI Making Us Dumber? Why Smart People Stop Thinking With AI

AI isn't exactly making us dumber. It makes it very easy to stop thinking without noticing. Four views on the research, and the habits all four agree on.

What the file found

  1. Failed

    Wharton: with AI, people scored 25 points higher when it was right, 15 lower when wrong, and grew more confident.

  2. Failed

    Anthropic's trial: engineers who learned with AI averaged 50% on the quiz, the hand coders 67%.

  3. Failed

    Turkey: plain ChatGPT lifted practice scores 48%, then students did 17% worse once it was taken away.

  4. Held

    AI set up as a tutor, hints not answers: practice scores up 127%, and most of the harm was gone.

The test to run this week

Before you trust an answer, ask: could I explain this and defend it without the AI in the room?
