What-I believe that most of the decisions I have made today were bias. And, because I have not or can not see the outcomes of those bias decisions yet, I can not conclude that bias decision leads to bad outcome. I remember there was an article saying about managers should make decision based on their first thought to the problem, first feeling, instinct. The reason in a real business world, there is no much time to make a rational decision. Especially, in urgent situation, managers are usually required to respond to the problem very quick and only a few minutes are left for the decisions to be made. Therefore, they have to make the decisions based on their experiences or perceptions. My opinion is that, after today's lecture, I agree that the process of rational/critical thinking is very important to day-to-day life. And in order to be critical, I need to think critically about critical thinking.
Why- Why it is important? As I mentioned earlier, time is the currency in 21st century. And the cost of wasting or losing time is much greater the cost of anything. Making a very rational decision is quite costly. However, you can argue that what measures a VERY rational decision. I don't know honestly speaking. I am not a critical thinking person, so most of time I make decision based on my "feeling" within a few seconds. And the outcome is sometimes it works well, sometimes it is very bad. SO, it seems like that the when is the critical time to make decision rationally becomes quite important.
How-Further to the question, I have not found an satisfied answer yet. But at least I have come up with more thoughts about critical thinking which is good. The base rule I apply to critical thinking everyday is by asking myself: what, why, and how. Although I admit that sometimes asking what why and how could lead me to more confusion, most of time it takes me out of the fog.
