This chapter delves into the concept of the predictive brain and its influence on how we think, feel, and behave. It draws from various sources including Malcolm Gladwell's 'Blink' and Lisa Feldman Barrett's 'How Emotions are Made' to explain how unconscious decisions shape our thoughts and actions. The brain uses past experiences to make predictions, impacting everything from eating a bagel for the first time to the way we perceive sensory inputs like sight and hearing. It explores phenomena such as blind spots in vision, the McGurk effect in auditory perception, and inattentional blindness demonstrated by the famous invisible gorilla experiment. The chapter emphasizes the interconnectedness of sensory systems and how our emotions can alter our perceptions, advocating for conscious awareness to improve our understanding of reality.
