Cynicism refers to a belief or attitude characterized by skepticism, distrust, and negativity towards human motives and actions. Cynics tend to question and criticize conventional values, institutions, and social norms. Originating from the ancient Greek philosophy of cynicism, cynics view the world as fundamentally flawed and driven by self-interest. They often use sarcasm and irony to express their doubts and little faith in humanity. While cynicism can be seen as a defense mechanism against disappointment and deception, it can also lead to a lack of trust and pessimism.
