From a quick google search common-sense is defined as “good sense and sound judgment in practical matters.” This definition sums up common-sense fairly well. But I look at common sense as the ability to make fewer mistakes and make better decisions.
Daily we make different decisions. Some have major impacts on your life, and others are minor. Although if we start thinking and making these decisions using the concept of probability, we will ultimately make better decisions. Which will lead to a healthier and better life.
