• Persona-Model Collapseconcept0.750
  The central concept introduced by this paper: deterioration of a model's internal capacity to simulate, differentiate, and maintain consistent characters
• Can mode collapse be mitigated at inference time without retraining the model?question0.741
  Motivates the VS approach as a training-free solution
• collapsed awarenessconcept0.727
  Attentional mode of deep fixation and tunnel vision, epitomized by Gemini 2.5 and associated with doom spirals.
• Different prompt types collapse to different modes: instance prompts collapse to a single prototypical response, while distribution prompts collapse to a representative high-entropy sampleclaim0.724
  The theoretical mechanism explaining why VS works despite mode collapse remaining operative
• Out-of-distribution collapse in foundation models is the same failure mode as Levin's regeneration failures and Alexander's lifeless buildings: loss of multi-scale coherence under stress.claim0.711
• What is the fundamental cause of mode collapse in post-training aligned LLMs?question0.707
  The central question the paper addresses, answered by identifying typicality bias as a data-level driver
• Do these failure modes (overbidding, self-bidding, bankrupt initiation) generalise to other economic settings?question0.699
  Remains untested whether the specific LLM failures observed in CATTLE TRADE extend beyond this game.
• Do these failure modes generalise to other economic settings?question0.697
