He is Senior Research Psychologist at the American Institute for Behavioral Research and Technology (AIBRT) and the former editor-in-chief of Psychology Today magazine. A Ph.D. of Harvard University, he has published 15 books on artificial intelligence, parenting, and other topics, as well as more than 300 scientific and popular articles. His 2015 report in the Proceedings of the National Academy of Sciences (PNAS) on the “Search Engine Manipulation Effect” (SEME) describes one of the largest effects ever discovered in the behavioral sciences, and because SEME is invisible as a source of influence, it is an especially dangerous form of influence. Dr. Epstein’s research suggests that SEME is currently determining the outcomes of upwards of 25 percent of the world’s national elections and that it is affecting a wide range of opinions, not just voting preferences. SEME is one of eight powerful new online manipulations he has discovered and is studying. A thought leader in the behavioral sciences, Dr. Epstein is typically interviewed by journalists more than 50 times a year. He is currently working on a book called Technoslavery: Invisible Influence in the Internet Age and Beyond.
