Mary Sharpe, Chief Executive Officer

Mary Sharpe was born in Glasgow and grew up in a family dedicated to public service through teaching, law and medicine. From a young age, she was fascinated with the power of the mind and has been learning about it ever since.

Education and Professional Experience

Mary completed a Master of Arts degree at the University of Glasgow in French and German with psychology and moral philosophy. She followed this with a Bachelors degree in law. After graduation she practised as a solicitor and Advocate. For the next 13 years Mary worked in Scotland and at the European Commission in Brussels. She then undertook post graduate work at the University of Cambridge and became a tutor there for many years. In 2012 Mary returned to the Faculty of Advocates, Scottish Bar, to refresh her court craft. In 2014 she went non-practising to set up the The Reward Foundation. She remains a member of the College of Justice and Faculty of Advocates.

University of Cambridge

Mary attended the University of Cambridge in 2000-1 to do post graduate work on sexual love and gender power relations from the period of Classical Antiquity through to the early Common Era. These conflicting value systems still influence the world today.

Sustaining Peak Performance

Over 2001 to 2003 Mary trained as a workshop facilitator at the University in personal leadership development. The workshop was developed by two international, award-winning organisations and based on psychology and neuroscience research. As technology was becoming more embedded in people’s lives, what kind of skills do people need today in order to flourish? To answer this Mary designed a 2 day workshop for the University of Cambridge’s graduate development department. The workshop was called “Sustaining Peak Performance”. It is a practical, evidence-based course to show how we learn, change habits, make decisions and be aware of the risks around overuse of technology for entertainment. The focus was on developing resilience to stress, connecting with others and becoming effective leaders. She also worked as a mentor to enterprise students and a science writer for the Cambridge-MIT Institute. This is a joint venture between the Massachusetts Institute of Technology (MIT) and the University of Cambridge.

Research Developments

Her affiliation to the University of Cambridge remains through both St Edmund’s College and Lucy Cavendish College where she is an Associate Member. Mary spent a year as a Visiting Scholar at St Edmund’s College, University of Cambridge in 2015-16. This allowed her to keep apace of the research in the emerging science of behavioural addiction, particularly internet pornography. During that time she spoke at a dozen national and international conferences. Mary published an article on “Strategies to Prevent Internet Pornography Addiction” available here (pages 105-116). She also co-authored a chapter in Working with Sex Offenders – a Guide for Practitioners published by Routledge.

Mary continues the work on behavioural addiction as a member of the International Society for the Study of Behavioural Addiction. She publishes research on this emerging area in peer reviewed journals. The latest paper can be found here.

The Reward Foundation

The idea to make the scientific research about sexual love publicly accessible first crystallised in 2006. That year Mary presented a paper on “Sex and Addiction” at the Third International Positive Psychology conference in Portugal. The internet was only starting to become a concern. However the idea for creating the foundation really developed after 2012 as a result of the following event.

Technology Entertainment and Design (TED)

The TED concept is based on “ideas worth sharing”. It is an education and entertainment platform available both as live talks and online. Mary attended TED Global in Edinburgh in 2011.  Shortly thereafter she was  asked to co- organise the first TEDx Glasgow event in 2012. One of the speakers attending was Gary Wilson who shared the latest findings from his website about the impact of online pornography on the brain in a talk called “The Great Porn Experiment”. Since then that talk has been viewed over 11.6 million times  and been translated into 18 languages.

Gary Wilson expanded his popular talk into an excellent book, now in its second edition, called Your Brain on Porn: Internet Pornography and the Emerging Science of Addiction.  As a result of his work, thousands of people have stated on porn recovery websites that Gary’s information inspired them to experiment with quitting porn. They have reported that their sexual health and emotional problems began to diminish or disappear thereafter. To help spread the word about these intriguing and valuable social health developments, Mary co-founded The Reward Foundation with Dr Darryl Mead on 23rd June 2014.

Our Philosophy

People sometimes ask us if we use porn. The answer is “no, we don’t”, but we do not want to prohibit others from doing so. It is a personal choice. However we do want to help people be in a position to make an ‘informed’ choice based on the evidence from the research currently available especially if they have developed problematic use.

We campaign to reduce children’s easy access to internet pornography because dozens of research papers indicate that it is damaging to children at their vulnerable stage of brain development. There has been a dramatic rise in child-on-child sexual abuse in the past 6 years, in porn-related sexual injuries according to healthcare professionals who have attended our workshops and possibly even deaths. We are in favour of the UK’s Government’s Digital Economy Act 2017 requiring age verification for users as it is a first and foremost a child protection measure. It is not a silver bullet, but is a necessary good starting place. It will not replace the need for education about risks. And who benefits if we do nothing?

Awards and Engagement

Our CEO has received a number of awards since 2014 to develop the work of the Foundation. It started with a year of training through the Scottish Government-supported Social Innovation Incubator Award. This was delivered at The Melting Pot in Edinburgh. It was followed by two start up awards from UnLtd, two from the Educational Trust and another from the Big Lottery Fund. Mary has used the money from these awards to pioneer digital detoxes in schools. She has also developed lesson plans about pornography for teachers to use in schools. In 2017 she develop a one-day workshop accredited by the Royal College of General Practitioners. It trains professionals about the impact of internet pornography on mental and physical health.

Mary joined the Board of Directors of the Society for the Advancement of Sexual Health in the USA in 2016. She is chair of the Press Relations and Advocacy Committee. She is also active in the National Organisation for the Treatment of Abusers. Here she contributed to a paper on Prevention of Harmful Sexual Behaviour Mary also delivered 3 workshops to practitioners about the impact of internet pornography on harmful sexual behaviour.

In 2017 Mary was made an Associate at the Centre for Youth and Criminal Justice at the University of Strathclyde. Her initial contribution was speaking at the CYCJ event on 7 March 2018 in Glasgow.  Grey cells and prison cells: Meeting the neurodevelopmental and cognitive needs of vulnerable young people. In 2018 she was nominated as one of the WISE100 women leaders in social enterprise.

When not working on the charity, Mary enjoys walking, swimming, travelling and dancing.
