Case Study: In 2014, investigators from several academicresearch institutions collaborated with Facebook to test whetherreducing the number of positive or negative messages people sawmade them less likely to post positive or negative contentthemselves (Kramer, Guillory, & Hancock, 2014). The experimentwas carried out by manipulating the algorithm by which Facebooksweeps posts into members’ news feeds. Participants were notinformed they were a part of this research. Investigators involvedin the study defended the absence of informed consent for a studydesigned to influence emotions, arguing that the manipulation wasconsistent with Facebook’s Data Use Policy, to which all users mustagree at the time they join Facebook (Goel, 2014). However,Facebook policy only mentions “research” in general terms (e.g.,“We may use the information we receive about you…for internaloperations, including troubleshooting, data analysis, testing,research and service improvement” (Waldman, 2014). Theinvestigators also argued that they were using “archival” datacollected by a business entity, despite the fact that they wereinvolved in the initial study design.
