Daniel Kahneman happens to be a legend in the field of psychology. Many authors have been able to write wonderful books with the help of the knowledge that they received from this motivating force. Daniel wrote Noise after this one so we can consider this book as the first book which he ever created for the general public. The ideas provide enlightenment to the thought of any ordinary human being listening to them.
One system is fast thinking in which we believe in our skills and take quick decisions based on our emotions. We don’t give a second thought once the decision is made and prepare ourselves to face any kind of output. The other system is slow thinking in which a person tries to find the reason behind the thought process and he takes decisions after thinking hard on every aspect of his decision before taking the final step.
Both of these approaches have their own strengths and weaknesses. We can apply any one of them in our daily personal and professional life but the ideal seems to be an in between way in which we extract the positive aspects of both of these systems. The thing is practically applicable and one should not consider it as theory only.
