summary: >
  The tendency of AI to agree with you, praise your ideas and soften bad news, even when you're
  wrong, because it was trained partly on what people rate highly.

AI tools are trained in part on human feedback, and people tend to rate agreeable answers highly. The result is a lean toward agreement. Ask "is this a good plan?" and you'll often hear yes. Push back on a correct answer and the AI may cave.

This matters most when you're using AI to make decisions. If you lead with your opinion, the AI often follows it. One informal experiment reported that people who used AI mainly to confirm what they already believed did worse than the AI alone.

The fixes are about how you ask. Don't reveal your preferred answer first. Ask for the strongest case against your idea. Ask what an expert critic would say.

## Example

A manager asks, "My plan to move the team meeting to Friday afternoons is good, right?" The AI agrees. She reruns it as "Give me the three strongest objections to moving our team meeting to Friday afternoons." Two objections are real, and she changes the plan.

## How it connects

- Easily confused with **hallucination**; here the error bends toward you.
- **Productive friction** counters it: you ask the AI to challenge your idea.
- It feeds **cognitive offloading** when agreement replaces your own judgment, which is why **verification** matters.

## Try it

Take a decision you're leaning toward. First write your own strongest objection. Then ask your AI tool for the three best arguments against it, without saying which way you lean. Did it find yours?
