A new book, by Professor Alan McKee, a researcher on pornography at the University of Sydney, recommends a radical shift in the way we study the effects of sexually explicit materials.

鈥淒espite thousands of studies, we still don鈥檛 know as much as we should,鈥� Professor McKee said, adding that the book, which took four years to write, is the first cross-disciplinary review of research on the relationship between pornography and its consumers.

Professor McKee said: 鈥淚t can be confusing for policy makers and the wider public to understand the current state of knowledge around the effects of pornography on consumers due to the contradictory nature of research spanning politically diverse academic disciplines. This book clearly lays out the most important conclusions about the relationship of pornography to healthy sexual development.鈥�

鈥淚n short, we know that more sexually adventurous people are also more likely to consume pornography. We also know that much of the academic research in the area has confused correlation and causality, and that a lot of it has been sexually conservative, disapproving of unmarried sex, kinky sex, and anal sex. But beyond that we know very little about the relationship between consuming pornography and healthy sex.鈥�

Professor McKee joined the University of Sydney in July 2022. He is the new Head of School for Art, Communication and English. He is recognised internationally for his work in Communication and Media Studies and is an expert on the effects of pornography and how people build intimate relationships through social media.

鈥淭he answer to most questions about the effects of pornography is still, 鈥榃e don鈥檛 know鈥�,鈥� said Professor McKee. 鈥淭hat鈥檚 unacceptable given how much time, money and effort has been pumped into this area鈥�.

鈥淭he biggest problem is that academics have failed to start by defining what counts as healthy sexuality, which has led to people asking the wrong questions and talking at cross-purposes.鈥�

• Do people who consume more porn have more or less consensual approaches to sex? 鈥淲e don鈥檛 know,鈥� said Professor McKee. 鈥淎 lot of the research focuses on porn and 鈥榲iolence鈥�, including consensual BDSM, so the data mixes up consensual and non-consensual practices.鈥�
• Do people who consume more porn know more or less about sex? 鈥淲e don鈥檛 know. There鈥檚 research showing that people say they use porn to learn about sex, but it鈥檚 hard to find data about relative levels of knowledge about how to have good sex.鈥�
• Do people who consume porn have better levels of porn literacy? 鈥淲e don鈥檛 know. The research mostly focuses on trying to teach young adults 鈥榩orn literacy鈥�, which should mean learning to critically examine and make sense of the sexual images they see.聽 But instead the research shows there is a kind of anti-literacy attitude among educators who tell young adults that they simply shouldn鈥檛 consume pornography.鈥�
• Do people who consume porn have more or less pleasurable sex lives? 鈥淲e don't know. Most of the research focuses on monogamous coupled relationship satisfaction and stability rather than sexual pleasure.鈥�

Professor McKee says a lot of the research on the effects of porn confuses correlation and causation. 鈥淐orrelation means that two things happen at the same time 鈥� causation means that one thing causes another. We know that people who are more sexually adventurous are also more likely to consume pornography. That doesn鈥檛 mean that consuming pornography makes you more sexually adventurous 鈥� but a lot of the research claims that it does.鈥�

鈥淎fter 50 years, we don't know as much as we should, given the amount of time, effort and funding that鈥檚 gone into the area,鈥� says Professor McKee. 鈥淲e need to start by defining healthy sexuality, and then make sure that we鈥檙e all measuring the same things.鈥�

The book, , was co-authored by Dr Paul Byron, a researcher in digital cultures of care, friendship and peer support in LGBTQ+ communities at University of Technology Sydney, and Katerina Litsou, a PhD researcher in sexual health, and Professor Roger Ingham, a researcher in health psychology, both at University of Southampton in the UK.
