Researcher from Cornell University, Jon Kleinberg and Facebook senior engineer Lars Backstrom analysed data of 1.3 million users of the social media network who were listed as being in a relationship, and found that their break-up can be predicted as a result of their mutual friend circle.
According to news.com.au, theory of dispersion states that couples with high dispersion have mutual friends who are not well connected while those with low have mutual friends who are well connected.
Therefore, if a couple shares low dispersion, they are less likely to have their own lives and more prone to break-up.
Facebook stated healthy relationship, as one where both partners have connections to a lot of different groups of people, even if those friendships aren't particularly strong.
Kleinberg explained that a spouse or romantic partner is a bridge between a person's different social worlds, the report added.
