System 1

System 1 refers to one of two modes of thinking described by psychologist Daniel Kahneman in his book "Thinking, Fast and Slow." System 1 is characterized by fast, automatic, intuitive, and emotional responses. It operates quickly and effortlessly, drawing on experiences and heuristics to make judgments and decisions. This system is responsible for everyday decision-making and quick reactions in familiar situations. In contrast, System 2 is slower, more deliberate, and more analytical.
