Mean world syndrome is a mental bias in which we see the world as a dangerous place more that it is in reality due to having been exposed to issues of extreme violence on television.
Mean world syndrome occurs to us in a form of fear, anxiety , pessimism and always feeling like there are threats all around us. Media is the powerful tool that influence this behaviour due to how it portrays the world stories to the viewers.
The increasing violence stories portrayed on TV daily makes a person who watches television constantly start believing that the world is real an extreme dangerous place based on what they see on TV.
