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

Decoding the Gurus

In this academic-themed interview episode of Decoding the Gurus, 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.

We also learn about the dangers of being STUPID: Studying Topics Uninformed by Prior Investigations in the Discipline, and attempt to uncover just how much Chaz enjoys popping balloons.

A fun one that might even leave you a little bit more optimistic than usual!
