Our brains are biologically designed to save energy, which often leads to “cutting corners” in our thinking. As popularized by Daniel Kahneman, we have two modes of thought: System 1 and System 2. System 1 is “fast”—it’s instinctive, automatic, and emotional. While great for riding a bike, it’s “dumb” and prone to cognitive biases.
System 2, conversely, is “slow,” analytical, and deliberate. It’s the “cautious lawyer” you use when buying a car or solving complex problems. Because System 2 is mentally draining, we often default back to the impulsive System 1. To think clearly, you must gain awareness of when you are reacting purely on instinct and force yourself to “jump immediately” to the more rigorous, logical System 2.
