Thinking Fast and Slow by Daniel Kahneman

The book tells us that our mind combines two systems: System 1, the fast-thinking mode, operates effortlessly and instinctively, relying on intuition and past experiences. In contrast, System 2, the slow-thinking mode, engages in deliberate, logical analysis, often requiring more effort.

Kahneman highlights the “Law of Least Effort”; the human mind is programmed to take the path of least resistance, and solvingcomplex problems depletes our mental capacity for thinking. This explains why we can’t often think deeply when tired or stressed.

He also explains how both systems function simultaneously to affect our perceptions and decision-making. Humans require both systems, and the key is to become aware of how we think so we can avoid significant mistakes when the stakes are high.
