How this node ties into the rest of the map, and the evidence behind each link.
Systematic probabilistic reasoning failures in LLMs motivate studying training dynamics to understand why these biases emerge and persist.
+4 growthFinding that LLM reasoning is driven by attention-head pattern-matching rather than abstract world models explains probabilistic reasoning limitations.
