Thinking is most beautiful ability of human being. Human mind developed that ability during the course of evolution. How our decisions, policies, bias, judgements forms? We will find that today. No worries I will not use those Hard words which are complex to understanding. Using simple examples and images you will get to know that.
Let’s simply take example what is 2+2=? Instantly answer comes in your mind without thinking was 4 but now what about 97 + 19? Is it requiring some mental effort to calculate? The addition 2 + 2=4 was repeated much more times in our daily life that it requires no mental effort such a type of thinking is called as fast thinking or system 1 thinking. The system which requires mental effort is as system 2 Or slow thinking. This both systems require for our mind. Each thinking types has its own pros and cons.
