Think slowly. Decide quickly.  The great ones are leaving...

I was deeply saddened to learn about the death of Daniel Kahneman, an outstanding psychologist, Nobel Prize winner and author of the bestseller "Think Slowly. Decide quickly."

His work has had a huge impact on many areas, including product development and mentoring.

How I used Kahneman's work in my work:

  • Understanding Cognitive Biases: Kahneman's book helped me better understand how people make decisions, and how cognitive biases can affect this process. I use this knowledge when developing products to make them more user-friendly and attractive to users.
  • Applying Behavioral Patterns: Kahneman describes a variety of behavioral patterns that can be used to create more effective products. For example, I use the default principle* to recommend the most profitable options to users.
  • Improved communication: Thanks to Kahneman, I have a better understanding of how people perceive information. This knowledge helps me communicate more effectively with my team and clients.

Cognitive Skills development: I recommend that my students read Kahneman's book so that they can better understand how their brains work and how to make more rational decisions.Overcoming cognitive distortions: I help my students to be aware of cognitive distortions that can affect their judgments, and teaches them how to deal with them.Developing Critical Thinking: Kahneman's book teaches people to think critically and not to take everything at face value. This is an important skill for anyone who wants to succeed in life.Why it's worth reading the book "Think Slowly. Decide quickly":

The book is written in an accessible language and will be understandable even to those who do not have a special education in psychology.The book contains many real-life examples that will help you better understand how cognitive distortions work.The book will help you make more rational decisions in various areas of life.

The default principle is a cognitive heuristic according to which people tend to choose the option that is offered by default if they do not make efforts to change it.

Kahneman in his book gives many examples of the use of the default principle in various spheres of life,

Here are some examples:

  • Organ donation: In countries where organ donation is the default option (i.e., people automatically become donors if they do not refuse), there is a higher level of donation compared to countries where donation is not a default.
  • Retirement plans: People are more likely to choose the default retirement plan, even if it is not optimal for their needs.
  • Investments: Investors are more likely to choose the default investment portfolios, even if they do not meet their investment goals.

The default principle can be used to create more efficient products.:

  • Recommendations: offer users the most profitable option by default.
  • Settings: Set the default settings that will be most convenient for users.
  • Registration: Make the registration process as simple and straightforward as possible so that people don't give up on it.

It is important to note that the principle of default is not always ethical.

Some companies use it to manipulate people and force them to make choices that are not beneficial to them.

Therefore, it is important that companies act in the best interests of their customers when using the default principle.

In general, the default principle is a powerful tool that can be used to create more effective products.

However, it is important to use it with care and responsibility.

Additional examples:

  • Language selection: Websites and applications often offer a default language that corresponds to the user's region.
  • Newsletter subscription: When registering on the site, a subscription to the newsletter may be enabled by default.
  • Saving settings: When the program is started for the first time, the default settings can be saved.

It is important to understand that the principle of default can have both positive and negative sides.

On the one hand, it can help people make the choice that suits them.

On the other hand, it can be used to manipulate people and force them to make choices that are not beneficial to them. P.S. It remains only to advise you to read or re-read the author's work. R.I.P. Daniel Kahneman
