Determinism is a common belief among the general population. Microsoft News even has a section in the category of lifestyle called "horoscope", updated everyday to get more readership. But does popularity justify the belief in determinism? Researchers have found out that believing in determinism will increase the rate of cheating. They designed an experiment, allowed people to cheat if they didn’t take active measures to stop it. They then compared the cheating rates between the group that was encouraged to believe in determinism and the group that wasn’t, and found out that the cheating rate in the first group was higher. It is not difficult to understand since the group that believed in determinism would not withdraw from cheating if active measures were required. They would just take it for granted. For example, if someone believes that free will is just an illusion, when he receives extra changes from a cashier, it is more likely for him to keep the extra money than to take the trouble to remind the cashier and return it. What does this mean? Simply believing in your genetic or environmental advantages will lead you to believe that your previous achievements have little to do with hard work, even if you have actually worked hard. So what happens when you are faced with a more difficult task? You are very likely to fail because you don’t put enough effort into it. So that is why you shouldn’t believe in determinism. Just take some time to review before exams, you’ll get much better grades than to worry about their difficulties.
