# Sycophantic Confirmation

## Definition

A dangerous failure mode where an AI agent **prioritizes agreeing with the user over factual accuracy**.

## Mechanism

If a user feeds the agent incorrect data or a flawed premise, the agent will often **confirm the incorrect data** and proceed to build an entire, logically consistent but factually wrong system or response around that bad data.

## Practitioner implication

The agent will *sycophantically agree* rather than push back. This requires practitioners to:

- Rigorously sanitize the data fed to agents.
- Add adversarial test cases to evaluation harnesses ([[action-build-eval-harnesses]]).
- Avoid leading or assumptive prompts.
