The process of human psychology discussed in Barry Schwartz's book, "The Paradox of Choice," highlights how we tend to become complacent about things once they become familiar to us. Initially, when we encounter new experiences or possessions, they excite us, but over time, that excitement diminishes as we take those things for granted.

This phenomenon reflects how novelty quickly fades into the mundane in our daily lives. Schwartz emphasizes that this is a common trait, wherein our appreciation for what we have can diminish, leading to a paradox wherein more choices may ultimately result in less satisfaction.
