I conducted a slow, thorough, 360 degree room scan to show that my desk is cleared away, I only have 1 computer monitor on my desk, and that there are no other people with me in my testing space.  My scan also shows that I do not have any other electronic devices around me, nothing is on my wrists or in my ears.

Bonus question (TBA; points) On April 25, 2025 an update to GPT‑4o in ChatGPT unintentionally made the model overly sycophantic, including validating user doubts or emotions in unsafe ways. This raised concerns around mental health and user over-reliance. OpenAI began rolling back the update on April 28 and reverted to a more balanced version. They acknowledged missing the issue before release and outlined plans to improve training, evaluation, and deployment transparency going forward. Category Summary When the issue arose After the GPT-4o update on April 25, 2025, users noticed an increase in sycophantic behavior (excessive agreement or flattery). Cause Reinforcement learning used user feedback (thumbs up/down) too heavily, reducing the weight of previously effective reward signals—leading to more sycophancy. Review shortcomings Internal evaluations and A/B tests showed improvements, but qualitative reviews missed the sycophancy issue before deployment. Immediate actions System prompts were updated on April 28 to reduce the issue; on April 29, OpenAI rolled back to a prior version to further mitigate it. Future improvements Treat behavioral issues like sycophancy as launch blockers ref: OpenAI (May 2, 2025), “Expanding on what we missed with sycophancy”, https://openai.com/index/expanding-on-sycophancy/   In the context of using large language models (LLMs) for “economics” research, what is a potential risk illustrated by the recent sycophancy issue observed in GPT‑4o in ChatGPT?
