Before we begin we need to define exactly what a troll is. According to Wikipedia a troll is “In Internet slang, a troll is someone who posts inflammatory, extraneous, or off-topic messages in an online community, such as an online discussion forum, chat room, or blog, with the primary intent of provoking other users into a desired emotional response or of otherwise disrupting normal on-topic discussion.”
The definition in my opinion is spot on but it certainly doesn’t tell us what motivates an internet troll. Not being one myself I can not really tell you with any kind of first person experience. I can offer you the opinions of others though.
Why so aggressive?
In my own opinion I do not think there is any singular reason why people feel like they need to be trying to insult others on the internet but rather a combination of a number of factors. A very nice article about exactly this came from Michael Marshall of the prestigious New Scientist publication back in 2007. You can read the full post here but here are some points that I found interesting:
“Social psychologists have known for decades that, if we reduce our sense of our own identity; a process called deindividuation, we are less likely to stick to social norms. For example, in the 1960s Leon Mann studied a nasty phenomenon called “suicide baiting“, when someone threatening to jump from a high building is encouraged to do so by bystanders. Mann found that people were more likely to do this if they were part of a large crowd, if the jumper was above the 7th floor, and if it was dark. These are all factors that allowed the observers to lose their own individuality.”
“Another obvious factor is that, if you insult someone online, it’s unlikely you’ll face any physical retaliation for it. Epley compares the resulting psychological distance to being isolated inside a car, another situation that seems to make people more prone to abusiveness.”
