How Does Consciousness Work? | Anil Seth

Perception Creation

Perception is not merely a passive reception of sensory information but an active process of prediction and construction. Anil Seth explains that our brains are constantly making predictions about the world and using sensory signals to update these predictions, creating a balance between inputs and outputs 1. This process results in a unique interpretation of reality for each individual, leading to perceptual diversity.

Perception is as much a creative act of writing as it is of reading.

--- Anil Seth

This diversity is evident in phenomena like the viral dress image, where people saw different colors, highlighting how our brains project perceptions based on individual differences 2.

   

Illusions & Reality

Illusions reveal the discrepancy between perception and reality, showcasing the brain's predictive nature. Alex J O'Connor and Anil discuss how illusions like Adelson's checkerboard demonstrate that our brains are not designed to perceive reality accurately but to interpret sensory information in a way that aids survival 3. This cognitive impenetrability means that even when we know an illusion's trick, we can't unsee it.

Our eyes and brains were not intended to be light meters. They're intended to figure out most likely what's actually going on.

--- Anil Seth

Such illusions suggest that our perception is more about navigating the world effectively than seeing it as it truly is, raising questions about the nature of truth and reality 4.
