The Greater Internet Fuckwad Theory. First given a name by the boys at Penny Arcade, it is a theory that seeks to illuminate why so many people seem to degenerate into antisocial Jerkasses online, when they might only be mildly unpleasant or even polite in-person.

The equation is "Normal Person + Anonymity + Audience = Total Fuckwad".

This phenomenon has been studied in an academic setting, and, by all accounts, the satirical analysis is spot-on: normal people become more aggressive when they think their behavior carries no real-world social consequences. When people do not have to worry about getting in trouble with their loved ones, school, or place of employment, or getting into a direct physical altercation with anyone, they feel that they have nothing to lose by being shameless, insufferable jerks behind the veil of anonymity that is The Internet.

Hence the depressingly large number of people who think that being a cyberbully is funny, and that the Internet is the perfect place to spew all the bigoted, hypocritical, provocative, or otherwise hateful bile they would never say in-person. The GIFT also contributes to the pervasiveness of cyber-bullying among kids and teenagers, which has led to suicides. The academic name of the phenomenon is the Online Disinhibition Effect. It should be noted that the Online Disinhibition Effect cuts both ways; while some people become jerks, other people find the anonymity and lack of consequence on The Internet allows them to be more honest and talk about issues that, under normal circumstances, they would be unable to address. These issues can be as simple as liking a movie or show normally seen as outside their demographic or as serious as mental health issues, but, in either case, the exact same anonymity that turns some people into Jerkasses allows them to speak things that they might want to talk about but be unable to do normally for fear of social stigma.

The idea of anonymity's irresistible corruption due to lack of consequences and escape from restraints caused by being watched is extremely pervasive. Think of the people who leave unholy messes and/or graffiti in public restrooms. Nobody sees them do it, and they almost certainly wouldn't make such a mess in their own bathroom where they'd have to clean it up (hopefully), or when they're a guest in someone's home. The basic idea was first proposed by Plato in The Republic, where he recounts the myth of the Ring of Gyges, one of the original Invisible Jerkass stories. At least one psychology paper has confirmed that Internet anonymity is attractive to narcissistic, psychopathic, and sadistic people who take pleasure in making others suffer.

Of course, the advent of newer social media sites such as Facebook and comment feeds on certain news sites, which require people to use their real name and maybe even other details about themselves when posting, has put the theory a bit into question and re-evalutation, as plenty of people (barring the ones who use fake names and throwaway accounts) seem quite willing to be just as obnoxious, rude, bigoted, and abusive while posting under their real identity as people posting under a pseudonym. Lack of anonymity, it seems, might dissuade some people from being jerks, but it doesn't appear that it is as effective a way to keep people on good behavior as originally thought.

The only reason why it's not a law like Godwin's Law is because of the Fun with Acronyms.

Fun fact: the German, Norwegian, Swedish, and Danish word Gift means "poison"... which is oddly appropriate.
