Thinking, Fast and Slow by Daniel Kahneman (winner of the Nobel Prize) gives a detailed explanation of some very simple yet basic concepts with far-reaching results. This book will make you realise that you are not as free in your decision making as you think you are. Working on your subconscious, this book has the power to make a direct impact on your conscious thoughts thereby changing your perspective and altering the way you think. This book is aimed at helping you easily comprehend critical thinking processes like judgmental errors, decision making, perception, analytical thinking, and irrationality. The crux of this book is our intuition or 6th sense, as it is commonly called. Many times we tend to assume things without giving any proper thought to it or applying any logic or reasoning. Kahneman talks about mental processes using the terms System 1 and 2, which according to him, produce fast and slow thinking simultaneously. At large, the book deals with System 1 and its influences on System 2.
Key Takeaways
- How does the human mind make decisions?
- When do we take impulsive decisions and when do we indulge in deep thought before making decisions?
- Why does advertising work in terms of getting us to buy things or services?
- Why do we remember only painful memories, and forget the happy ones?
- How the human thinking process determines effective business models?
The two players inside our mind: Systems 1 & 2
A human mind can be divided into two major parts- System 1 and System 2. Though these terms are used in psychological studies, this book attempts to delve deeper into the subject and present the same as if they are two characters who are interacting with each other.
Ÿ System 1 is a quick and intuitive operator and has almost zero control, making its action automatic.
Ÿ System 2 concentrates on activities that demand attention, including analysis and calculations. This is also the system which deals with decision making in an individual's life.
System 1 is largely responsible for the subconscious mind, leading to the creation of what is otherwise called as the “gut” or “instinct”. There are instances where it can go wrong, but the fact that it can operate without much effort is a huge advantage. System 2, on the other hand, is responsible for analysis-driven decision making. Unlike going by intuition, System 2 needs a lot of effort to conclude things.

I can answer that in a second! But why?
At a glance, it does seem that System 2 is the core of it all. However, System 1 is where the main action is. While System 1 throws up complex ideas, System 2 ensures the orderly steps leading to it. A simple basic action like completing the sentence “Bread and --------“requires almost no effort on your part. This is something you can answer even in your sleep. On listening to loud music all of a sudden, your first action is invariably to try and find the source of the sound (System 1). Though a little while later, you consciously ignore the sound and proceed ahead with your work. The ignoring of the loud music is an action executed by System 2. The fill in the blank of “bread and butter” is an automatic task being done by System 1. But something as simple as giving your telephone number to someone cannot be done without System 2, as it requires attention to the task.
Why are some decisions taken from the gut?
Surprisingly enough, System 2 has the capacity to alter the functionalities of System 1. Multitasking is possible only if all, or at least a few, of those tasks are easily doable and do not demand your complete attention at any point in time. Whenever our mind is given a set of instructions to follow, we tend to set System 1 to work on it. Typically called being blind to the obvious, it emphasizes that we don't even realize when we turn a blind eye and to what. System 1 is where the belief of “feeling right” is born, which is not necessarily right. It could be over-confidence or just plain simple ignorance of many other existent factors. We need System 2 to help us take a rational decision.
How do the two systems work with each other?
System 2 is activated whenever System 1 finds itself in a situation which is beyond its call of “automatic” duty- like solving some difficult problems which might involve calculations or damage control. System 2 can also be called the monitor of System 1, responsible for the alertness while driving at night or asking us to be polite when we are angry. System 2 tries to curb the impulsiveness of System 1. Attention & effort go hand in hand, one often overriding the other, leading to relative decision making. In absence of rationality, the human mind tends to rely on intuition and believes it to be the ultimate truth.
Why are we seduced by advertising?
We tend to judge a person socially basis two things- One our own judgment in the initial meeting and two, the views of a person close to us who knows the other person as well. People tend to draw conclusions basis the skills and virtues listed by others rather than factors like luck and other things at work. When

Do you remember the picnic or the flat tyre?
The duration of an experience plays almost no role in creating an impact on either of the systems. Instead, what is important is the feeling that it invokes-leading to imprints on the systems. If I am out for a picnic and have enjoyed the whole day, but in the end came back with a flat tire- making me push the car for quite a distance- I would choose to remember the picnic bitterly rather than smile thinking about the fun I had during the day. The next time I plan a picnic, I will be more cautious about my planning, especially when it comes to the vehicle that I will use to go to the picnic. This is where System 2 becomes active as it stores such memories and thereby gives birth to a certain set of fears and beliefs.
Why do we doubt happiness?
Human lives are largely defined by experiences and incidents. Surprisingly enough, we tend to remember all the emotions we felt during those incidents or experiences and not just the conclusion. If it had a happy ending, the jubilation would be occupying a very small part of our System 1 but the feelings that those moments evoked would be etched very deeply in System 1. Whenever we tend to think about those moments, our mind invariably goes back to those feelings, and not the conclusion of it- triggering a plethora of emotions in System 1. When we don't pay attention to what we are doing and choose to go with the flow, we end up taking some very wrong decisions, as at that time we allow those emotions to rule our mind, and not System 2-which would have rather analyzed it in depth and in a better fashion.
Should you take quick decisions?
System 1 is not prone to doubt, and it believes without any logic or reasoning. Any ambiguity is suppressed by it unless there is something that comes across as immediately negative to the mind. And that is where System 2 comes into the picture, as it tends to doubt. But there are high chances that people tend to get overconfident believing that their intuition not only works very strongly but correctly too. Anyone depending on such decisions and executing them is taking huge risks. You are highly prone to make miscalculations, leading to incorrect decisions when it involves huge risks. But share brokers, bankers and other such people who have to take such decisions day in and day out get used to switching off that side of their mind and heavily rely on System 1 to make such decisions.
How human psychology helps build business models?
Analyzing the above we can conclude how these studies have directly or indirectly laid the foundation of insurance and banking sectors, paving way for the financial structure of our society today. The core of

every framework hence becomes human psychology and heavily involves our beliefs and emotions. Just like the law of diminishing need works on the first morsel of food consumed leading to satisfaction, it also works on materialistic things we gather. This is true for the single yet firm belief that the future is promising, as well. What looks very dependable for a moment changes into a doubtful thing right after someone is successful in triggering our System 2 and putting it on active mode.
Being deliberate in our decision making is an important human ability. Knowing that the System 2 is behind this thinking process further makes us aware of System 2. However, imagine if every decision requires System 2 to come into play? What if we think every time before we take a breath? The world requires us to use both Systems 1&2.
What we should aim at is applying System 2 to decision making that requires deep analysis. Otherwise we will be in a perennial 'analysis-paralysis' mode.
