Unfortunately, cognitive ease makes us vulnerable to being influenced through simple repetition. The second set of words does’t have any overlapping connection, so you won’t get that same intuitive feeling. This feeling of cognitive ease happens even before they can think of the word that connects all three, which is cheese. When most people hear the first three words, they can intuitively sense they are somehow related. For example, can you sense a connection between these three words: Scientists have created a Remote Association Test (RAT) that demonstrates the feeling of cognitive ease. Kahneman calls this Cognitive Ease and mostly attributes it to System 1. One result is that ideas we have heard repeatedly before can feel intuitively true only because they spark recognition. When we hear one idea, it activates other ideas nearby in our mind. Our memory is a machine that makes constant connections. Cognitive Ease: Assuming something is true if it seems familiar However, they are not physically separate areas in the brain.Ģ. They help us explain the tendencies of the human mind.

Please note these two systems are like nicknames or useful shortcuts. Scientists know this system is working when someone’s eye pupils dilate or heart rate increases, both signs of cognitive effort.

System 2 is also our self control, regulating our impulses. It’s usually turned off and only engages when heavier thinking is needed, like if someone asked you to multiply 19 by 33.

System 2 is slow, analytical and lazy.

While System 1 is usually right, sometimes the quick judgments lead us to wrong conclusions, as in the example. It’s always working and recognizing connections between things.

System 1 is fast, automatic and intuitive.

This example illustrates the two systems in our mind: (The correct answer is that the bat costs $1.05 and the ball costs 5 cents.) Finding the correct answer requires a little more logical thinking. Most people immediately feel the ball costs 10 cents and the bat costs 1 dollar. Over 80% of university students give the wrong answer to this question. The bat costs one dollar more than the ball. The examples demonstrate the psychological concepts he later explains.Ī bat and ball cost $1.10. Throughout Thinking, Fast and Slow, Kahneman shares example questions we can use to test our own minds as we’re reading. Your Mind’s Two Systems: 1 is fast and intuitive, 2 is slow and analytical
