Scott Alexander explores potential links between perception of optical illusions and cognitive styles, proposing further research to investigate these connections.
Longer summary
Scott Alexander discusses the potential link between perception and cognition based on survey results about optical illusions. He notes that 'weirder' groups (e.g., schizophrenics, transhumanists, polyamorous people) tend to see more ambiguity in illusions like the Hollow Mask and Spinning Dancer. Scott proposes a research program to explore whether perception of optical illusions could predict cognitive biases or high-level beliefs. He plans to include more illusions in future surveys to better understand the underlying mental processes. While acknowledging the ambitiousness of this idea, he cites some supporting evidence, such as the involvement of NMDA receptors in both political opinions and illusion perception. Scott also considers potential confounding factors and how to address them in future research.
