Simon was extremely proud to be invited to speak at such a prestigious event. Using the philosophical concept of a social contract Simon demonstrated the enormous benefits of peer to peer interventions. Imagine if you were about to carryout a behaviour which placed either yourself or others in danger, wouldn’t it be amazing if one of your colleagues was able to step in and support you to make a better decision?. The response from those who attended the session was very positive and we look forward to hearing and feedback about interventions based on this idea.
