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.
