🔄FROM THE ARCHIVE: It's easy to overlook blatant, glaring aspects to our surroundings when we're hyper focused on a task. These neuroscience theories explain why.

of the world are constantly cross referenced with what our senses are telling us. This cross referencing inevitably leads to prediction errors, as our models don’t always neatly match up with what our senses tell us. These errors then play a vital role in helping the brain update it’s predictions, giving it more data to choose from for the next scenario in which it finds itself., Seth describes how generative models are the brain’s bank of perceivable content.

A high-level prediction like seeing a team of people passing a ball cascades down to lower level predictions like the type of clothing they are wearing, the kind of movements they are making, and the varying sounds that accompany them. These flow down to even lower level predictions about the shape of the ball, light bouncing off the floor, and the movement of these bodies in space.

If someone swivels their head around and catches a glance of a team passing a ball, then those visual sensory signals will have low reliability and won’t influence our perception as much as if we paused and stared at the team. Simply glancing at something will have the effect of down-weighting the estimated precision that those sensory signals have, and will therefore have less influence on our perceptual best guess.
