There are two types of common sense - good sense, which is using sound judgment and understanding things as they are, and folk wisdom, which is unreflective knowledge not based on training or thought. Developing common sense involves familiarizing yourself with its purpose and meaning, understanding how the mind can convince itself of ideas contrary to reality, acquainting yourself with reflective and rapid thinking, learning practical knowledge, establishing new thinking habits, and continually learning about yourself and others. Common sense is not always accurate, as psychological claims that seem like common sense are often untrue and should be evaluated critically rather than trusted solely based on intuition.
