Statistical research of online dating
Online dating has ballooned into a billion-dollar industry and the Internet "may be altering the dynamics and outcome of marriage itself," said the study by U. researchers in the Proceedings of the National Academy of Sciences.
However, some experts took issue with the findings because the survey was commissioned by e Harmony.com, the dating site that attracted one quarter of all online marriages according to the research.
"Nobody's surprised when a minuscule effect reaches statistical significance with a sample of 20,000 people, but it's important that we don't misunderstand 'statistical significance' to mean 'practical significance.'" Finkel also took issue with e Harmony's involvement in the study.
"I'm always a bit wary when a project is entirely funded by a private organization that clearly has a vested interest in the results," he said.
"These data suggest that the Internet may be altering the dynamics and outcomes of marriage itself," said Cacioppo.
