Facebook Didnt Get Permission For Mood Manipulation Experiment
Forbes' Kashmir Hill reports that Facebook did not actually have even implicit user permission to conduct a controversial study. In the study, Facebook caused the news feeds of nearly 700,000 unwitting Facebook users to show an abnormally lower number of either positive or negative posts. The study proved that the posts people saw could manipulate their emotions and determine how positive or negative they felt. Hill found that Facebook didn't change its Data Use Policy to include those use cases until four months after it conducted the November 2012 experiment. When it conducted its experiment, Facebook didn't ask users for their explicit permission to include them in the study. It didn't implicitly ask their permission when they signed up, either. Facebook denies that it conducted any research without users' permission. "When someone signs up for Facebook, we've always asked permission to use their information to provide and enhance the services we offer," a Facebook spokesperson told Hill.
