• Emotion subspace overlap (SVD-based)method0.838
  Metric measuring how much of an SAE feature vector lies within the 171-dimensional subspace spanned by emotion probes, via SVD orthogonalization
• SAE emotion subspace overlap correlates with variance-residualized persistence in Cogito: Spearman +0.413, p = 4.4e-196.finding0.809
  Strong positive relationship between emotion alignment and SAE feature persistence in Cogito
• SAE Feature #11100 associated with panic, 93rd percentile emotion subspace fractionfinding0.798
  Shows high emotion subspace overlap for a specific negative emotion feature
• Text-based and self-steered emotionality ratings for SAE features are correlated at only ρ = +0.051 (n.s.).finding0.771
  Shows low agreement between the two evaluation modalities
• The correlation between emotion subspace fraction and self-evaluated emotionality validates that emotion probe concepts somewhat overlap with the model's self-reported internal emotions.claim0.760
  Claim supporting the validity of the probe construction method via cross-validation with self-report
• 17 of 83 emotions tested show significant associations between SAE feature self-evaluation transcripts mentioning the emotion word and higher cosine similarity to that emotion probe; 67 of 83 have positive associations.finding0.753
  Demonstrates partial but reliable validity of self-evaluation for measuring probe emotionality
• SAE features that the model self-describes as more emotional tend to be more persistent than variance-matched SAE features.claim0.753
  Novel finding that agentic self-evaluation of emotionality correlates with feature persistence
• Self-evaluated emotionality and textual evaluation of SAE features predict persistence in opposite directions.claim0.753
  Surprising finding that the two evaluation methods diverge in their relationship with persistence
