The day the article ran, a Facebook team started investigating the “leakage,” according to documents provided by Frances Haugen to Congress and shared with The Markup, and the problem was escalated to the highest level to be “reviewed by Mark.” Over the course of the next week, Facebook employees identified several causes for the broken promise.
That technical oversight was compounded by a decision Facebook officials made about how to determine whether or not a particular group was political in nature.—a paid, nationwide panel of Facebook users who automatically supply us data from their Facebook feeds—we designated groups as political or not based on their names, about pages, rules, and posted content.
As a result, the company was seeing a “12% churn” in its list of groups designated as political. If a group went seven days without posting content the company’s algorithms deemed political, it would be taken off the blacklist and could once again be recommended to users. Social networking and misinformation researchers say that the company’s decision to classify groups as political based on seven days’ worth of content was always likely to fall short.
The internal Facebook investigation into the political recommendations confirmed these problems. By Jan. 25, six days after The Markup’s original article, a Facebook employee declared that the problem was “mitigated,” although root causes were still under investigation.
