Answer:
The retelling of urban legends over time ensures that they become part of public record and explains why they are so well known. Common examples include “Bloody Mary” – a woman who was once supposedly executed for being a witch and who will show her face in the mirror if you call on her. Hookman, which tells the story of a killer with a hook for a hand attacking a couple in a parked car, and the Vanishing Hitchhiker are also well known legends.
The strange thing is that notoriety and disproof do not prevent urban legends from resurfacing after going out of fashion for some time. Indeed, the enduring gang initiation urban legend recently re-emerged in this way. This is the claim that, as part of an initiation, gang members driving at night without headlights will pursue and shoot the occupants of any car which flashes them a warning.
Psychologically, urban legends are a way for us to make sense of the world and manage threat in a safe environment. From the perspective of believers, myths act as proof and reinforce existing beliefs. This is important because they help to validate an person’s worldview and in doing so legitimatises their fears as real and genuine.
Urban legends also provide a source of entertainment. Sharing them is an important form of social engagement. Passing apparently important information can make people feel helpful, despite a lack of evidence.
Within modern society, due to email and the internet, urban legends spread even more rapidly and indefinitely – constantly adapting to retain relevance, coherence and significance.
With these changes have come a generation of new viral urban legends. You may have heard the story about the two people who have cybersex only to realise months later that they are father and daughter. Another viral one is Slender Man, a creepy character who hangs around in forests and stalks children. This originated in 2009 on an internet forum as part of a Photoshop challenge in which participants edited photographs of everyday objects to make them appear paranormal.
