Here’s a surprise: Sheryl Sandberg’s non-apology for the experiment in which Facebook tweaked nearly 700,000 people’s News Feeds to determine the effect it might have on their emotions hasn’t stopped the condemnation of the study from privacy groups and the editor-in-chief of the journal that included the findings. EPIC, a privacy advocacy group, has filed an official complaint with the Federal Trade Commission to seek an investigation into the study. Meanwhile, the editor-in-chief of PNAS has published a statement in which she says that Facebook’s study might not have respected ethical standards. EPIC argues in its complaint that Facebook “purposefully messed with people’s minds” with an experiment made possible by the “secretive and non-consensual use of personal information.” The group alleges that this violates the FTC’s 2012 Consent Order with Facebook and Section 5 of the FTC Act. It requests that the FTC impose sanctions on Facebook and require it to “make public the algorithm by which it generates the News Feed” to repent for the alleged violations.
