So say students at Guelph University in Ontario.

“Is your significant other interrogating you, asking about your communication with people you used to date, or even with acquaintances you speak with infrequently?” asks Wired Campus, citing a paper intriguingly entitled, More Information than You Ever Wanted: Does Facebook Bring Out the Green-Eyed Monster of Jealousy?

And it’s not just any jealousy, say Guelph PhD candidates Amy Muise and Emily Christofides,and their adviser associate professor of applied social psychology Serge Desmarais.

They, “wondered whether spying on their significant others would make people question the partners’ honesty and fidelity, and if time spent on the Web site would increase as a result,” says the story, going on:

“More than 300 undergraduate students completed an anonymous online survey about their Facebook habits. Of those, a little more than half said they were seriously dating one person.”

Study results, “suggest that Facebook may expose an individual to potentially jealousy-provoking information about their partner, which creates a feedback loop whereby heightened jealousy leads to increased surveillance of a partner’s Facebook page,” say the authors, adding:

“Persistent surveillance results in further exposure to jealousy-provoking information. For many, the need for knowledge about their partner’s intent becomes indispensable, and several participants specifically mentioned the word ‘addiction’ in relation to their own Facebook usage.

“One participant who had recently broken up with her boyfriend stated, ‘It’s addictive. … I always findmyself going on there checking new pictures and screening them. I can’t help it’!”

Now you know.
