Your brain doesn't wait patiently for all the information to arrive before deciding what you're looking at.
According to Anil Seth's explanation of predictive processing in Being You, it's constantly generating its best guesses about what's around you and comparing those predictions with incoming sensory information.
Most of the time, those predictions are good enough that we don't even realise it's happening.
But when something unexpected appears — an unfamiliar shape in the dark, a noise you weren't expecting, something that looks "wrong" for a split second — your brain has to update its prediction.
It gives a very different picture of perception.
Rather than your brain simply receiving information from the world, it's actively involved in creating the experience you have of it.
🧠 Have you ever been absolutely convinced you'd seen or heard something, only to realise a second later that your brain had got it wrong?
