Critical thinking for better rational decisions

As per my knowledge, what I understood, Critical thinking is a thinking process involving analysis and keeping in mind the different factors to come up with better decisions. It is also important to know that where to apply Critical thinking and where to not. One of the interesting things was ‘kill your darlings’ where selecting a product which I like and then killing it by researching lot about the negative points and reviews. I also learned about different biases which affects the critical thinking process. Critical thinking is very helpful exercise and it keeps developing every time we apply. Our reasoning also develops and we make more rational decisions.
