After a study on whether emotional manipulation in the News Feed could make people sad turned into a PR disaster, Facebook has now set up a formal review process for pre-approving research on its users, and Research At Facebook website to centralize all the academic work done on its enormous data set. Facebook admitting to screwing up with the emotions study, explaining “We were unprepared for the reaction the paper received when it was published and have taken to heart the comments and criticism. It is clear now that there are things we should have done differently. For example, we should have considered other non-experimental ways to do this research. The research would also have benefited from more extensive review by a wider and more senior group of people. Last, in releasing the study, we failed to communicate clearly why and how we did it.”
