OTT Conference 2026: Think tanks and trust
In recent years, the ground beneath public life has shifted. Social and political trust is eroding, consensus has become an outlier, and evidence (once the currency of serious debate) too often appears dismissed, manipulated, or ignored. In such a context, one question arises with urgency: are think tanks still trustworthy and relevant actors?
This is the challenge and the opportunity that will define the 2026 OTT Conference. Trust will not be treated as an abstract ideal, but as a condition that determines whether think tanks can continue to shape the policy world. What is trust? Trust in what or whom, and why does it matter?

About the OTT conferences
OTT conferences are designed to create opportunities for both formal and informal interactions, allowing participants to create sessions on topics relevant to them.
The programme includes a public event on the first evening, followed by a lineup of keynote addresses, plenary and parallel sessions.
The programme includes extended coffee and lunch breaks for networking, a marketplace of ideas, and fringe events hosted by participating organisations throughout the week.
We invite all participants to use their time in Rabat to organise meetings and fringe events with other conference-goers. If you would like our support in connecting you with other participants from a specific sector or region, please reach out.
