Foreword: Neuroscience, the Internet and the Good Life by Professor Anthony Jack
Chapter 1: What Are We Dealing With?
Neuroscience, the Internet and the Good Life
Professor Anthony Jack
The human mind is shaped by the intersection of two powerful forces: biology and culture.
Cultural changes, in particular technological innovations, profoundly alter how we think. Yet these changes do not occur on a blank slate. The brain is a highly plastic, flexible organ. But it is also an accident of evolution, with numerous constraints. The written word, for example, has transformed our ability to understand the world, greatly accelerating changes in technology and fundamentally changing human consciousness. Yet, unlike verbal language, reading and writing do not emerge spontaneously from human sociability. Literacy only reliably arises as the product of well-organized social institutions dedicated to education.
Literacy requires training that alters the basic wiring of the brain. It takes serious work to organize neurons into a highly efficient specialized system that links visual processing to the verbal language system and manual motor outputs. Sustained and guided attention changes the structure of the brain and endows it with new powers.
The great promise of the rapidly advancing field of human neuroscience is that it can help us to
understand how cultural contexts interact with the brain to create the mind - how behaviours and ways of thinking inscribe themselves inside our skulls. It gives us a new way to put human consciousness under the light of scientific understanding. Neuroscience offers guidance that can help us fulfill our potential and avoid pitfalls along the way.
But we mustn’t fool ourselves that this emerging science will deliver quick and easy fixes – fixes like taking a pill, having surgery, or passing laws severely restricting what others are allowed to do
.
The best way to train our plastic brains to work effectively in their cultural context is through education, inquiry and contemplation, a process that takes a lot of time and patience.
The widespread availability of high-power computers, coupled with highspeed internet
connectivity, has ushered in an era of technological change whose capacity to shape human consciousness is comparable to the invention of the printing press. The internet is now everywhere. It is not just in the office buildings of the most developed countries, but also, through smartphones, in the hands of individuals of all ages everywhere. Information is flowing around the world at a quantity, speed, and with a lack of barriers that represents a sea-change from the past. This revolution is changing not just the information we have access to, but the very nature of how we ask questions (we google it), and the process we use to answer them: thinking is now as much a task shared with computers as a purely brain-based activity.
In recent years there has been widespread concern about the impact of the internet on our social
lives. The internet offers wonderful opportunities for people to connect in new and meaningful ways, yet it also threatens to make us socially disconnected. Many of us have hundreds of ‘friends’ on Facebook whom we interact with online at the cost of face-to-face interactions. Research has shown this often has a negative effect on our wellbeing. Technology is in danger of making us impersonal, of dampening our capacity and tendency for human connection.
Perhaps the most important example of the way that digital technology allows us to withdraw from ordinary interaction is pornography. In a healthy relationship, sex is associated with the highest levels of intimacy and trust. It is, or at least can be, the culmination and expression of our closest human connection. It not only helps to reinforce this connection, it also creates entirely new life.
Evolution shaped this basic human drive to build families: sexual desire is one of our most powerful motivational forces, and has been essential to the flourishing of the human race. Yet pornography transforms that drive into a force that primarily motivates the completely solitary and unproductive activity of masturbation.
Pornography has been present since before the dawn of civilization, and can be found on the walls of cave dwellers. Yet, it has never been less social, or more pervasive. It is well known that pornography has been the single most influential economic engine that has fuelled the expansion of the internet, including internet commerce. It is accessed in massive quantities on both computers and, more recently, smartphones, not just in the USA but increasingly across the entire world.
As a result of the internet revolution, young people don’t need to physically purchase pornographic content or obtain it from friends. The current cultural environment provides massive amounts of varied content that can be accessed for free and in complete privacy. Anyone with a highspeed internet connection can, if they choose, access more sexually arousing content in a few hours than the most obsessive and wealthy collector of a few decades ago could have amassed in a lifetime.
Finally, pornography represents the most important cautionary tale of how the internet can make us impersonal because of a great irony. It turns out that sex is such a personal issue that we are reluctant to speak about it in public. We don’t like to say so out loud, but the internet exists in its current form because it is, in large part, a collection of technologies that make access to pornography more convenient. Pornography is shaping the private consciousness of people all over the world, probably including most of the people you know, in a way that is quantitatively and qualitatively different from the past. It is past time for that private influence to become a subject for public deliberation.
Let me take a moment to clearly state what I believe is the best approximation of the truth, on a topic where objectivity is notoriously difficult. Addiction to internet pornography is a very real phenomenon with a very real impact on wellbeing. It is a phenomenon which has grown exponentially in the last decade, even though it has remained largely invisible and undetected by society. Tragically, its risks continue to be ignored or actively denied by all but a few enlightened medical professionals. It is a phenomenon that is not just here to stay, but also likely to increase. It is almost certainly the cause of the widespread sexual dysfunction found in recent studies of late adolescence

It is a problem that is most likely impacting you, or your loved ones, without you even being aware of it.
The core of this book comes from the blend of two things: scientific evidence and human experience. Pornography is as old as civilization, but this book provides a scientific account of why internet pornography is having a qualitatively and quantitatively different effect from most prior pornography. This scientific account is made vivid by the first hand reports of people who have been badly impacted by, and found a way to help resolve, their addiction to internet pornography. The account that you will read is solid. I am a professor in the fields of neuroscience, psychology and ethics. I have more than 20 years of education and research experience in those fields, acquired at world leading institutions in both Europe and the USA, and I actively teach and do research. Writing this foreword is an accident in my career – something I stumbled on by chance and which grabbed me when I realized its significance. I have never even met Gary Wilson, but I have paused to study his work and the academic literature carefully. I vouch for his account without hesitation. It is the most considered, thorough and accurate account of internet pornography addiction that exists at the time of writing.
Gary’s account isn’t the last word, and he would never pretend it is. However, it is far more insightful than accounts I have read by tenured professors at major research universities. Furthermore, unlike many of those accounts, Gary’s account is very readable. To be clear, both Gary Wilson and I feel very strongly that more research is needed, into the neuroscience of this particular addiction, and into effective therapeutic responses. Nonetheless, it is already evident that pornography poses a significant threat to the emotional wellbeing of many of its users, and it would be irresponsible not to acknowledge that threat as real and pressing.
The threat that internet pornography poses can be traced to the effects it has on the reward circuitry of the brain. This reward circuitry comprises a remarkable and complex system. It learns and changes with experience, and it is sensitive to many different sorts of rewards. The central nexus of this reward circuitry is a set of subcortical structures that lie just above and behind the eyes. These structures are usually referred to collectively as the ventral striatum, and activity in these structures indexes the degree to which a stimulus or behaviour is rewarding to the individual. Some rewards are very concrete. You won’t be surprised to learn that the ventral striatum fires when people eat chocolate and when they look at pictures of attractive scantily clad people. These are obvious atavistic rewards. Evolution shaped us to desire calorie rich foods and fit mates – we wouldn’t be here if our ancestors hadn’t been motivated to seek those things. Similarly, it isn’t very surprising that cocaine activates the ventral striatum – cocaine would never have become a popular drug of abuse if it didn’t.
However, the ventral striatum is not merely activated by drugs of abuse or stimuli whose associations with reward were hard wired into our brains long ago by evolution. The ventral striatum is strongly connected to and modulated by regions involved in social processing, and it is strongly triggered by rewards which depend on social context. For instance, stimuli which signal financial gains and increase in social status also activate the ventral striatum. It is very important to appreciate that the ventral striatum is not just associated with self-serving rewards, but also motivates prosocial behaviour such as charitable giving. The ventral striatum is highly sensitive to genuine empathetic social connection, including looking at a photograph of a family member, falling in love, altruistic acts, and even the simple feeling that someone has listened to you.
Great care needs to be taken when we move from talking about reward to addiction. When addiction is being discussed in a clinical context, for instance relating to substance abuse or dependency, then by definition it means a tuning of the reward system that is dysfunctional. That is, the medical phenomenon of addiction occurs when the reward system loses its balance and becomes over
tuned to prefer a type of reward that is demonstrably detrimental to our wellbeing. But the mere fact the reward system of an individual has become very strongly tuned to particular type of reward does not mean any dysfunction is present. In ordinary language, we recognize this fact. We might say that a friend is addicted to exercise, addicted to nature, addicted to reading literature, or addicted to charitable service work. Such ‘addictions’ can certainly exist, in the sense that people can have reward systems that are very strongly tuned to the rewards associated with these activities. Provided the tuning is not so strong that other important behaviours are completely displaced, these ‘addictions’
are far more likely to be healthy and functional, rather than unhealthy and dysfunctional. In particular, a great deal of recent research suggests that the more that people’s reward systems are tuned to forming social connections with others, the more likely they are to be both more physically healthy and more psychologically well balanced. This is what makes internet pornography addiction so troubling. It represents a tuning of the reward system from a very healthy type of reward, that of forming a genuine and intimate connection with another, into a type of reward that removes the user from social contact, and often leaves them feeling lonely and ashamed rather than connected and supported.
