1st of all , Why people forward chain mails?
Probably the most important point is the idea that viral email chain letters are “virtual urban legends” and as such many of the motivations that cause people to spread urban legends are the same that make people forward those emails.
Many urban legends function as warnings, if you break with social rules and roles you will be punished. Go to lover’s lane with your boyfriend and a crazy serial killer will come and kill you or him (or both of you). Disregard your parents’ dislike of unhealthy fast food and you may end up eating a rat.
As I mentioned briefly in a post last week humans evolved with strong rewards to develop imitation and social learning skills. Evolutionarily, people have a motivation to be susceptible to social warnings and pass them on to their family and community.
Perhaps the most subtle and powerful viral element of chain letters in email is the social proof that comes with many of them.with popular viral emails, it suddenly appears that the message is common knowledge and the receiver is perhaps the only person left on the internet who wasn’t warned of the danger. Even if you may think an email is a hoax, who are you to think that you know better than hundreds of your peers? And on the off-chance the email was true, and you didn’t pass it on you didn’t do your best to protect and enrich your friends and family.
