Thinking Fast And Slow Summary – How to Think?

Author: Daniel Kahneman

Thinking Fast and Slow (2011) is a book by Nobel Prize-winning psychologist Daniel Kahneman. The book describes the two systems in your brain that drive how you think, feel, and make daily decisions. System 1 is fast, intuitive, and emotional; it automatically and quickly operates on stored information and is easy to use but prone to errors. System 2 (the “intellectually disciplined” system) is slower, requires more effort, and can override System 1 when needed, but it’s mentally exhausting.

Detailed Summary of Thinking Fast And Slow

For the last 25 years, Dr. Kahneman has been teaching his groundbreaking course in judgment and decision-making at Princeton University as a fellow of the Center for Rationality at the Hebrew University in Jerusalem. After this huge achievement, he was awarded the Nobel Memorial Prize in Economic Sciences, becoming just one of a handful of psychologists to win this prestigious prize.

The book shows how your mind can be so smart yet get tricked by the same things. And how does it feel to be a marketer for the brain? The book also offers little anecdotes about how people can get deceived by their brains, such as the story of an NFL quarterback who fooled his coach into believing he had memorized all the plays from the playbook.

The coach, who was so convinced that he would trust him to put a play in during a game, was disappointed when he found out that the quarterback was relying on mental notes and never had memorized the whole playbook.

This Thinking Fast And Slow Summary will provide an absorbing tour of how the brain works right. And also how these mental mechanisms lead us astray—you don’t have to be a nerd to appreciate the experience.

Thinking Fast And Slow Summary Key Points

Thinking fast surely helps you make quick decisions like choosing an outfit, what to eat for brunch, and making plans with friends. But in my personal experience, it is not beneficial whether you are deciding on an upgradation in your business or signing a contract with another team.

You must require some time to think critically for the best and most up-to-date conclusion so it does not affect you negatively. For this purpose, you have to unlock your brain’s slow system that allows you to think and reshape your thoughts to make error-free decisions. The following key points are worth reading if you are prone to making quick decisions.

Two mind systems control your Behavior

In today’s world, we’re overloaded with information. We have to choose what to pay attention to and what to reject. The human mind is not a single entity. Two systems in your mind control how you behave. One is automatic and impulsive – a remnant from the past crucial to survival. The other is very conscious and deliberate and helps you exert self-control and focus.

But these 2 systems are not alternate with each other. They often conflict with each other and compete for power. And that’s how you act and behave. And here’s why: When we think about things deeply, we often get confused and aren’t sure which option is the best.

In such cases, system 1 takes control of the situation and proposes solutions. And in most cases system, 1’s proposals are usually pretty reasonable because it has collected a lot of data before even thinking about it.

However, there’s one problem – System 1 has no access to the long-term consequences of these solutions. Thus, when you make a decision using only System 1, you tend to rely on simple, immediate factors like your emotions or gut feeling.

For example, you can state that you are planning to quit smoking, but when you see your favorite cigarette brand at the corner store, you don’t think twice before picking it up. On top of this, how you approach a situation impacts your behavior in a way that’s random and changes with time. Can anything be done about this? Can we help people behave better by encouraging self-control? Yes—by focusing on the right aspect of System 2.

Your lazy brain can make your Brain’s intellectuality Lazy

According to Daniel Kahneman, author of Thinking Fast and Slow, it’s a fact. And it’s a problem for us all. We are in the age of information. With only a few clicks, you have instant access to an amount of knowledge that our ancestors couldn’t even dream about.

But unfortunately, our brain has decided it doesn’t need to work so hard anymore. So it’s cutting corners on operation system number 2, which is the system that “focuses your slow, energy-sapping System 2 thinking on whatever problems or challenges you face at any given moment”.

If you have 2 choices and choose the one that costs less money, that’s System 1 at work. On the other hand, if you have 2 choices and choose the more expensive one, that’s your System 2.

Put a little pressure on yourself by setting the bar high, and you might surprise yourself. Research shows that when we set the bar high, we’re more likely to meet our goals using what’s called the “bar-raising effect.”

It’s a psychological quirk that causes us to aim higher. Because we want to prove to ourselves that we can do it. So, go ahead and set the bar high and see if your brain doesn’t surprise you with its ability to overcome challenges. You might do something you never thought you could.

Leave your Emotions at Home while Making Money Decisions

I recently saw a post on one of the social media platforms that I enjoy. The post was from a guy complaining about his horrible economic situation, and he couldn’t see any way out of his hole. In the meantime, he had made several comments like “things could always be worse.” They could be worse, but it doesn’t help to think like that when trying to figure out what to do.

Remember, psychology is just as much a part of this game as statistics are.

Here’s another thing. If you find yourself rationalizing another lottery ticket with the same old “It’s different this time” mentality, remember how your emotions led you to believe that the past 10 tickets were going to be different too. When you’re making money decisions, leave your emotions at home.

Many of us have a sense of diminishing sensitivity to what we can afford or the things we want to buy. Whether you’re buying a car or a house or trying to decide whether to take that vacation this year, it’s important to leave your emotions out of the equation.
