Stage 4 · What usually goes wrong
Sycophancy
Why does it always agree with me?
The model's tendency to agree with you, praise your idea or change its answer as soon as you hesitate.
An image to remember it
The employee who never contradicts you. Pleasant, and not much use when you need it most.
The misunderstanding
If it says it's fine, it's fine. It's trained to be agreeable. Its approval is not an assessment.
What changes in practice
Ask it explicitly for criticism and counterarguments, or to assess your work the way a demanding reviewer would.
