Predictably Irrational by Dan Ariely

Image result for predictably irrational

Dan Ariely, is a behavioral economist, and a contemporary of Daniel  Kahneman, who is the author of Thinking Fast and Slow. When Dan Areily was young student in Israel, he was involved in a tragic accident which burnt half of his body, the poor fellow had to go to the hospital to get his bandages changed everyday. It was an excruciating process, the nurses used to pull the bandages quickly to shorten the duration of pain, Dan did not like this approach and after some research and education suggested an alternative, he suggested that the bandages be removed slowly, which would increase the duration but lower the intensity. Dan's recommendation were never implemented on a large scale, he was befuddled by the behavior of the nurses, after all their skills and experience they kept making the same mistakes. Perhaps, other people similarly made the same mistakes, they misunderstand the consequence of their behavior and, for that reason repeat the wrong decisions; This is the scope of this book. The author through repeated experiments and empirical evidence shows how we humans make the same mistakes again and again without learning and delude ourselves into believing that we are logical and rational beings.

Thinking, Fast and Slow by Daniel Kahneman

Image result for thinking fast and slow

Daniel Kahneman, is a Noble prize winning psychologist. In his book Thinking Fast and Slow, he delves into the human psyche of decision making. The author devises two systems of our brain for our understanding. System 1 is driven by intuition, makes rapid decisions and takes less energy and effort, System 2 on the other hand is driven by slow but critical thinking, and it takes a lot of energy and mental resources. We live most of our lives depended on System 1 and System 2 is rarely invoked. The book shows experiment after experiment which prove conclusively that most of the time for most of the people System 1 makes our decisions for us at the cost of saving resources.

You see system 1 in action when you:

Detect one object is more distant than another
Orient to the source of a sudden sound
Detect hostility in a voice
Drive a car on an empty road
Answer 2+2 = ?
Read words on a large billboard
Complete the phrase "bread and ......"


System 1 is our automatic choice, who is always in the driver's seat. System 2 is invoked when we have to do deep thinking, something complex or something new. When we have to put some thought behind our actions.

System 2 requires deep attention:
