  • Mar 15 2013: Common sense is looking at the situation, evaluating it using the knowledge you have and past experiences and reacting to it in the sensible way. We call it common sense and not reason because sometimes we are not able to pinpoint the logic that was used or all the data that we used to come to our decision. When someone looking at a situation and feels that it is a dangerous one, they are not normally able to pinpoint what made them enter fight or flight mode. Our animal bodies have evolved to sense danger by using sensory input and previous experience. We are just not able to easily explain it or understand it, so we call it common sense.

    Knowledge is the data we have accessible to us.

    I am a physics major. I know science. That being said, quantum mechanics does not increase my common sense or give me an advantage in day to day activities (other than when I am doing physics). Knowing the trajectories of balls in the park allows me to know when to duck. I can also determine whether certain physical things make sense, like climbing a precarious staircase or setting up a latter. Understanding some psychology allows one to understand how people work so that they can say or do the right things, or gain more insight into people. Science is a tool that we use to understand this data that we receive. It is how we understand and evaluate it in a more accurate way. For example, the more I learn about psychology, the more I am able to understand why some of my friends act the way they do. Science explains the world around us and gives us a way to understand what is going on as well.
