Skill 3: LLM as Simulator（LLM模拟器思维）

Core Principle

Don't ask what the LLM thinks. Ask it to simulate what a diverse group of experts would argue.

LLMs are trained to please. A direct question gets a sycophantic answer. A simulation request gets a distribution of real perspectives — including the uncomfortable ones.

Karpathy's method: write a draft → ask LLM to argue the strongest possible opposite position → synthesize a better view.
