(作文参考答案如下) What causes people ’ s irrational behavior? There are a lot of people who behave irrationally, causing problems to themselves as well as to others. It ’ s hard to analyze the exact causes behind irrational behavior, but we know that it is a manner of behavior that is not based on logic and reasoning. Irrational behavior is caused by various factors but two stand out. The first main factor that contributes to irrational behavior is uncontrolled emotions. Irrational people take offense or get angry before the actual situation occurs. They become anxious and express exaggerated emotions such as crying and shouting. They have unrealistic expectations, expecting everyone to like them and if someone does not, they feel angry and neglected. It is fairly common for people to show such signs of irrationality. Too much stress can also lead to irrational behavior. In fact, these days, stress is the major cause of physical as well as mental problems. Stress creates feeling of anger, irritation and frustration. For instance, when you spend a stressful day in the office, it makes you anxious. You start releasing your frustration or stress by screaming at your family members for small reasons like a badly prepared meal. That day you feel everything is wrong. In summary, uncontrolled emotions and too much stress can result in irrational behavior. To behave rationally is not an easy job because the behavior is internalized . However, to discover the source of your irrationality will help you behave more rationally.
