Although it is not something approved from a social point of view, the reality is that lying is an easy path, while the truth can lead to certain problems or difficult situations to be faced. That is why people lie, since it is a tool to interact socially. In most cases it is not a frequent resource nor is it serious. But when this becomes constant and obsessive, it is a problem. This is the case of mythomaniacs, popularly known as compulsive liars.
Mythomania is a psychological disorder, the people who present it are characterized by constantly telling lies. And, above all, for doing it even without a purpose. Being untrue almost always has an objective: to attract admiration, protect the ego, avoid conflicts, among others. However, a mythomaniac transcends that line and sometimes lies without a reason behind it. It is an addiction, that is the main differentiating feature of these people.
Mythomaniacs are people used to lying, so they will have no problem doing it at any time and in front of anyone. The naturalness and fluency with which they release their lies can make it not so easy to identify them. But if you pay attention to these common features, it will not be difficult to unmask a mythomaniac.
