The research, based on a survey of U.S. adults, found that 31% admitted to snooping on a partner’s phone without permission. The Digital Diary DilemmaIn the past, snooping might have meant rifling through a desk drawer or flipping through a diary. Being married or in a long-term partnership does not grant automatic access to a partner’s private device. In divorce proceedings, judges often deem evidence obtained through unauthorized phone access inadmissible. The TakeawayThe study’s findings are clear: phone snooping is far more than a harmless peek into a partner’s private life.
