Validation of genuine cognitive mechanisms versus spurious shortcuts
Develop validation methodologies that determine whether observed reasoning patterns in large language model traces reflect genuine cognitive mechanisms rather than spurious reasoning shortcuts or memorization.

Overall, our analyses expose fundamental gaps: we cannot know which training produces which cognitive capabilities a priori, cannot ensure behaviors transfer beyond training distributions, and cannot validate whether observed patterns reflect genuine cognitive mechanisms or spurious reasoning shortcuts.
Several of these datasets are public (HCP, OpenNeuro), so a frontier model may have encountered the associated published findings during training; we cannot rule out memorization, which is a further reason not to treat these results as novel detections.
The current experiment cannot distinguish these explanations, and a minimal-sufficient-evidence ablation would be required to do so.
Because our black-box design cannot directly observe training weights, attention mechanisms, or retrieval rankings, we cannot establish this as the underlying causal mechanism. Rather, the observed error pattern suggests a systematic tendency to reproduce pre-amendment legal reasoning in scenarios requiring recognition of subsequent statutory change.
So the classifier is directional only; it cannot attribute Qwen's higher flag count to genuine process differences, a reading we leave open (\hyperref[sec:limitations]{Limitations}).
However, we conjecture that these traces still provide evidence for examining model behavior.
Do these transitions constitute emergence''? Both the notion ofemergence'' itself and whether transitions such as these constitute emergence remain debated \citep[inter alia]{weiEmergentAbilitiesLarge2022, schaefferAreEmergentAbilities2023,niuIllusionAlgorithmInvestigating2025}.
