What happens behind closed doors during peace talks? Adam Cooper, senior program manager at the Centre for Humanitarian Dialogue and host of The Mediator’s Studio, talks to Olga and Hugh about the hidden world of peace diplomacy and how social media has changed it.  Adam shares what he has learnt from talking to seasoned mediators on his podcast, the challenges they face behind the scenes, especially when online disinformation has to be factored into the process. They also discuss cyber mediation as a response to the increased deployment of digital tools by conflict actors, the question of who is responsible for monitoring the dissemination of harmful content online and other negative – and positive – cyber trends on his radar.  For more information: The Mediator's Studio podcast.
