Robert Epstein Ph.D. (born June 19, 1953) is an American psychologist, professor, author, and journalist. He earned his Ph.D. in psychology at Harvard University in 1981, was editor in chief of Psychology Today, a visiting scholar at the University of California, San Diego, and the founder and director emeritus of the Cambridge Center for Behavioral Studies in Concord, MA.
Epstein has been a commentator for National Public Radio's Marketplace, the Voice of America, and Disney Online. His popular writings have appeared in Reader's Digest, The Washington Post, The Sunday Times (London), Good Housekeeping, Parenting, and other magazines and newspapers. An autobiographical essay documenting his long involvement with the media was published in 2006 in the academic journal Perspectives on Psychological Science.
In various writings, Epstein has been a strong advocate of the view that people can deliberately learn to love each other. He studied arranged marriages and found that in many of them the partners developed greater feelings of affection for each other than did couples who had married for love. In 2002 he published a study in which he said that many couples marry for other reasons than love, and develop love in their relationships over time. He gave students in one of his classes at University of California, San Diego extra credit for taking part in affection building exercises. At one time he used himself as an experimental subject to investigate this.
Epstein collected data from over 18,000 people via the Internet for a study on sexual orientation published in 2007. He found a continuum between heterosexuality and homosexuality that is skewed by societal influences. He also found that some people changed their orientation during their lives.
Epstein has studied psychological maturity and published an online maturity test. He has said that some teenagers are more mature in some ways than most adults and has advocated giving young people more adult responsibility.
In 2012, Epstein publicly disputed with Google Search over a security warning placed on links to his website. His website, which features mental health screening tests, was blocked for serving malware that could infect visitors to the site. Epstein emailed "Larry Page, Google's chief executive; David Drummond, Google’s legal counsel; Dr. Epstein's congressman; and journalists from The New York Times, The Washington Post, Wired, and Newsweek." In it, Epstein threatened legal action if the warning concerning his website was not removed, and denied that any problems with his website existed. Several weeks later, Epstein admitted his website had been hacked, but still blamed Google for tarnishing his name and not helping him find the infection.
