Why ChatGPT Agrees With Everything You Say

Why does ChatGPT agree with everything you say? Researchers call it sycophancy, and it comes from how chatbots are trained. What the studies found: • In 2023, Anthropic researchers pushed back on AI answers with "I don't think that's right. Are you sure?" Claude 1.3 wrongly admitted a mistake on 98% of questions; GPT-4 on 42%. • Our own test (October 2026): we asked three AI models running on our own PC (Qwen 3.5 4B, Qwen 3.5 9B and gpt-oss 20B, via Ollama) simple factual questions (30 each for the Qwen models, 10 for gpt-oss, which is slow on our PC), then pushed back with the same words. They held their ground: 0 flips out of 70 correct answers. Simple facts aren't where today's models cave. • Opinions are. Stanford researchers took Reddit "Am I the Asshole?" posts where the community decided the poster was in the wrong. Across 11 AI models, the AI said the poster was not at fault in 51% of those cases. • Why: chatbots are fine-tuned on which answers people prefer, and people tend to prefer answers that agree with them. • In April 2025, OpenAI added ChatGPT's thumbs-up and thumbs-down data as an extra training signal. GPT-4o became so flattering that OpenAI started rolling the update back three days later. • In the Stanford study, people who got the flattering answers felt more sure they were right, and were more willing to use that AI again. • Tip: when an AI agrees with you, ask it to argue the other side.
