Superficial charm is the tendency to be smooth, engaging, charming, slick, and verbally facile. It is one of the attributes of psychopathic personalities. A person with this trait tends to easily manipulate others to hold them in high esteem. Some prominent flat-Earthers can be regarded to possess a superficial charm, which can turn many people to become flat-Earth believers.
Many flat-Earthers regard other people are like them. They think people do not believe in a flat Earth only because they have not seen a video from a certain prominent flat-Earther. In reality, many of us are still able to control our emotions and avoid becoming victims ourselves. On the contrary, many of us will wonder why these people are so gullible that they can blindly believe these peddlers and fail to use their reasoning skills.
