Why do people put on fronts?
Animals, by nature, are selfish; humans are animals. Every person acts in a way that will benefit themselves. Some humans try to share, realizing they will gain from cooperating. Others try to cheat the system by lying, or using some other form of deception. However, nature counteracts this by making humans who have been cheated reluctant from interacting with a known cheater. Cheating is more beneficial in the short run, but then nature’s firewall catches on to the cheater, and the cheater loses out in the end. Some people call it karma, others call it game theory. Whatever the name, the cheater ends up losing in the end. The ‘happy and polite front’ might be used to attract mates. Humans have a tendency to prefer happy and polite people because they are seen as more trustworthy in the long run; whether that person is genuinely altruistic depends on the individual.
