What condition stems from watching news reports or hyperviolent programming and is based on the belief that the world is more dangerous than it actually is?

Mean world syndrome

Explanation:

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.
