Episode notes
Müller-Lyer Illusion in Animals
- Guppies and other animals like pigeons, horses, and bearded dragons perceive the Müller-Lyer illusion.
- These findings challenge the idea that the illusion depends on human cultural environments.
Illusion Exists Beyond Carpentered Spaces
- The geometric optical properties underlying the illusion appear in both natural and artificial environments.
- Thus, the illusion does not rely on exposure to modern carpentered spaces exclusively.

- Müller-Lyer illusions occur even without straight lines or arrowheads, demonstrated with curved lines and face patterns.
- This indicates the illusion does not depend on culturally common architectural features.
