Mind, Culture & Visual Illusions: Dorsa Amir and Chaz Firestone on Visual Illusions

Matt and Chris sit down to chat with Dorsa Amir and Chaz Firestone (@chazfirestone) about their recent paper 'Is Visual Perception WEIRD? The Müller-Lyer Illusion and the Cultural Byproduct Hypothesis.' In a conversation that serves as a welcome tonic to the endless lamentations of the gurus about academic groupthink and closed-minded silos, Dorsa and Chaz discuss the interdisciplinary nature of their work, debates around universal vs. culturally specific psychology, and the strength of evidence that visual perception varies between cultures. A fun one that might even leave you a little bit more optimistic than usual!
