How often do we really think we are making the right decision? Or, do we really think that whatever we have assumed or professed as true indeed? What about all those decisions we have made all these years? Does it always make us more contented that we’ve made them or was there any slight doubt that we would’ve thought a moment before we made that decision? Does being regretful is anywhere related to the decision we make or does that not at all related to our thinking minds? There are thousands questions for a questioning mind when you begin to read this book. In first few pages itself all our so called beliefs that we held dear to us all these years will be shattered brick by brick. That doesn’t mean that, this is a book that changes your thinking overnight and you can be more assertive and cognitive in an instant.

A book like “Thinking, Fast and Slow” is not a one time affair to read end to end. It has more to do with the assessing our minds in each page we turn. The decisions we make consciously or unconsciously have a profound impact on the overall journey of our life. Daniel Kahneman, a Nobel laureate, has crafted a well analyzed, well researched, well documented book. Each and every experiment or survey that he has conducted throughout his life about decision making, cognitive assessment, character forming, opinions that we have on all and sundry has been articulated exceptionally in this book.

One such example where I liked the most is, when the author and his associates conducted a survey on “was Gandhi older or younger than 144 years when he died?” Obviously, the answer the public gave was less than 144 years. When the same set of people asked a different aspect of this question like “how old they thought when Gandhi died?” and this time people picked up the answers as between 80’s and 90’s. On the next attempt when the people were asked “if Gandhi was older than 44 when he was died?” the expected answer was older. When he asked “how old Gandhi was when he died?” most of the people picked up the answers in late 50’s and 60’s. This particular experiment shows that, people tend to come up with their own set of beliefs in answering a question that had nothing to do with the reality and certainly had no impact on their choices. This is just a tip of the ice berg when it comes to convincing people. The people at marketing department knew the nerve of people and they try every way to manipulate its target customers by feeding information subtly and manipulate them into making decisions in favor of them.

There are sections from the book where the author deals with the concepts of forming an opinion on persons. What do we really think when we decide about a person as so and so? Do we really care about going to the deeper level of research before deciding the character of a person or do we just form an opinion with the vague information that is available before us? One such example that we can read from the book is about a female who is banker and a feminist. So most of the opinions formed on this particular case are, either the woman is a banker or a feminist. The question of she being a feminist banker seems an absurd opinion. But why do we make such assumptions? What runs in our mind when we read bits of information on a person and we have a picture of themselves with all the characters that we assumed that fits into that person? Author expressed his opinion that, most of us will use limited information to make decisions on someone. The questions we ask ourselves most of the time is, “Can we trust them?” “Are they friendly enough?” “Are they going to be a good human being?” “Are they competent enough?” etc…

This brings us to the main argument. Are we really making our decisions emotionally rather than rationally? Author explains in simple two system concept. System 1, in which a person reacts to almost everything instantly. It is devoid of mind body co-ordination. This is explained with a simple 2X2 multiplication. And, there is System 2, which is more rational and laid back. It never responds to events in a jiffy. It consents our mind before blurting out the response. A simpler example to this is, computing the results for 17X34. System 2 always monitors the System 1.

In conclusion, reading this book has shaken me greatly. I am convinced by the vast amount of research work about the psychology of the decision making that most of my choices so far in life have been taken without having a second thought. “What if?” reactions were always ringing in my mind while I was rummaging through the pages. Taking a decision in haste and try to rationalize it later is what we have practiced in all our lives. We try to come to terms with it than to analyze in the beginning.

Author was right on when he convinces his argument that people are incredibly quick to jump to conclusions, make decisions without enough information, and have their decisions greatly influenced by the bits of information they have in their hands. This book will certainly makes you think twice about how you make the decisions. Slowing down the process and thinking right is the one take away from this book while you read and savor it.

My Rating:
