Convergence Point Theory: Why LLM uncertainty is determined by the topic, not the model

Existing research on LLM response uncertainty has been looking in different directions. Hallucination, knowledge conflict, RLHF limitations, prompt sensitivity, calibration failure - these have all been studied separately, and I kept wondering why no one had tried to unify them under a single principle. I ran experiments on the hypothesis that the common cause of these phenomena lies not inside the model or in the prompt, but in an attribute inherent to the topic itself. A Convergence Point is the consensus density of knowledge humanity has accumulated on a given topic.
