Evidence

The Wall Street Journal reported that the Facebook data science group had run more than 1,000 experiments since its inception in 2007 and operated with “few limits” and no internal review board. Writing in the Guardian, psychology professor Chris Chambers summarized that “the Facebook study paints a dystopian future in which academic researchers escape ethical restriction by teaming up with private companies to test increasingly dangerous or harmful interventions.” — Shoshana Zuboff, The Age of Surveillance Capitalism, 950
