Welcome to another enlightening episode of Decoding Academia. In this bonus preview of our highly secretive Patreon content, we are discussing a controversial paper by Dorsa Amir and Chaz Firestone that challenges the established notion of the Müller-Lyer illusion being a product of cultural environments.

Prepare yourself for some high-level discussions of the visual processes of guppy fish and bearded lizards, as well as the remarkable lengths that psychologists will go to in order to get people to complete their tests. Will our seasoned scholars unravel the illusion, or is this debate another eye-catching mirage?
