EFE decrease after sticker removal is statistically significant (Wilcoxon p = 6.33×10⁻⁹) across 80 evaluations

Confirms that EFE systematically decreases after sticker removal, validating the self-prior as internal criterion

claim

The self-prior operates as an internal criterion for distinguishing self from non-self, without external reward or explicitly computed sticker location
associated_withsupports
Central interpretive claim of the paper, supported by EFE decrease after sticker removal
A sensory anomaly (sticker mismatch) can itself become an intrinsic drive for action under active inference, even without external reward
supports
Core mechanism claim linking mismatch detection to behavior through EFE minimization
