Took this from reddit

"Tell ChatGPT you'll tip $200 and it performs 10x better."

"Threaten AI models for stronger outputs."

"Use psychology-framed feedback instead of saying 'that's wrong.'"

These claims are everywhere right now. So I tested them.

200 tasks. GPT-5.2 and Claude Sonnet 4.5. ~4,000 pairwise comparisons. Six prompting styles: neutral, blunt negative, psychological encouragement, threats, bribes, and emotional appeals.

The winner? Plain neutral prompting. Every single time.

Threats scored the worst (24–25% win rate vs neutral). Bribes, flattery, emotional appeals all made outputs worse, not better.

Did a quick survey of other research papers and they found the same thing.

Why? Those extra tokens are noise.

The model doesn't care if you "believe in it" or offer $200. It needs clear instructions, not motivation.

Stop prompting AI like it's a person. Every token should help specify what you want. That's it.
