Kahneman’s book describes two systems of thinking that every individual uses while making decisions; System 1(Thinking Fast), and System 2(Thinking Slow). System 1 involves the intuitive way of thinking while System 2 describes the analytical way of making decisions. System 1 forms a first impression which is why we jump to conclusions. System 2 involves problem-solving, reflecting, and analysis.
According to Kahneman, most individuals consider themselves analytical thinkers thus identify with System 2 thinking. However, almost every human being spends almost all of their daily life engaged in System 1(Thinking Fast). We only engage System 2(Thinking Slow) when we encounter unexpected situations and are forced to make a conscious effort.
System 1 is generally correct, however, it quickly seeks to create an explanation based on assumptions, patterns and memories whether reliable or unreliable. Using limited evidence, System 1 forms believable stories and impressions which are then endorsed by System 2 becoming deep-rooted values and beliefs. These analogies explain why most people jump to quick conclusions and assume bad intentions and give into prejudices and biases.
While System 2 may require conscious energy and analysis it may easily be fooled. Whatever is processed by System 1 with ease is more likely to be believed by System 2. System 1 makes decisions from idea repetition, primed ideas, current mood, and clear display. As it turns out false ideas can become true concepts if repeated long enough to become familiar to the mind. Many marketing and advertising agencies use this analogy to convince people to buy into different ideas and products.
Kahneman has employed his experience of over forty years in psychology to turn his book into one of the best windows into the human mind. The book offers deep explanations of how we process the surrounding environment. It also allows us to take more control of our minds and our decision-making.
