The 3 Pillars of Neural Hallucination
1. Maximum Likelihood Bias

Neural LLMs are trained to maximize $P(w_t \mid w_{

2. Autoregressive Exposure Trap

During generation, every sampled token is appended to the prompt as ground truth without back-tracking. If sampling noise ($T>0$) picks a distractor token $w_k$, the model conditions all future tokens on that fiction, creating an inescapable confabulation chain.

3. Uncalibrated Manifold Voids

In high-dimensional spaces ($d \approx 4096$), true training samples occupy a thin curved submanifold. In between factual clusters lies immense empty space where softmax extrapolates arbitrary smooth probability gradients, rendering the model blindly overconfident.
