A new study suggests that there is a relationship between increased Facebook use and divorce. But don't delete your Facebook account yet: the researchers themselves admit that they have found a correlation between the two, not causation.
The researchers, who published the study in the July 2014 edition of Computers in Human Behavior, first looked at the rise of Facebook use and the rate of divorce in individual states. They found that a 20% increase in the number of Facebook users in a given state is associated with a 4% increase in the divorce rate the following year. However, the researchers could not identify who exactly was creating new Facebook accounts: it could have been young teens allowed to log on to the site for the first time or older people finally catching on to the trend. The people increasing their Facebook use were not necessarily the same people who were getting divorced.
The researchers also looked at survey information from individuals across the country aged 18 to 39. They found a weak relationship between marriage quality and social media use: those who spent more time on Facebook, Twitter and other sites were more likely to be unhappy with their marriage and thinking about ending it. However, an easy explanation for this correlation absolves Facebook: rather than social media sites causing people to be unhappy with their marriages, people who are unhappy (whether with their spouse or their life in general) could be turning to Facebook and other social media as an outlet. Individuals use Facebook to talk to friends, connect with old acquaintances and browse news and information—all of which can be used as a distraction from the less pleasant realities of life.
As the researchers conclude: "The study does not establish a cause-and-effect relationship because that would require longitudinal and/or experimental data."
Sure, the Internet has made it easier to find mistresses and simpler to track a spouse's cheating. But in the end, the individual has agency. Being exposed to exes, old friends or strangers online perhaps makes cheating more tempting, but it doesn't encourage cheating. Similarly, a person may be inclined to monitor their partner's activity, but that person can also choose to trust his or her significant other. In short, if a cheater is going to cheat, he doesn't need Facebook (0r even the Internet) to accomplish that goal.
