Susanna Siegel

American philosopher who argued that perception has rich representational content (including properties like causation and natural kind membership) and that cognitive penetration can undermine the rational standing of perceptual beliefs.

Rich content thesis: perceptual experiences represent complex properties, not just colors and shapes. Hijacked experience: when beliefs penetrate perception, the resulting perception loses independent epistemic standing as evidence — it is bootstrapped from the very belief it seems to support.
