The Think Tanks and Civil Societies Program of the Lauder Institute at the University of Pennsylvania, CLAEH University and the Konrad Adenauer Stiftung hosted the 2018 Latin America Think Tank Summit under the theme “Think Tanks: A Bridge over Troubled Waters and Turbulent Times.” The summit was held September 12-14th, 2018 at the Hilton Garden Inn Montevideo, Montevideo, Uruguay. The most influential and innovative think tanks in Latin America gathered to discuss contemporary issues they are facing, such as growing trade tensions, economic turbulence, climate change, mass migration, corruption and traditional and non-traditional security threats. In a world where facts, evidence, and credible research are often ignored, this summit explored how think tanks can remain relevant and impactful by simultaneously pursuing rigor, innovation, accessibility, and accountability more than ever before. As such, the summit explored not only the ways in which think tanks are currently making a difference and finding solutions to contemporary policy challenges, but also how they can become increasingly relevant in these tumultuous times. To that end, in addition to these pressing contemporary policy challenges, the 2018 Latin America Think Tank Summit also focused on sharing the best practices for raising funds, recruiting key staff, harnessing new and innovative technologies, and responding to increased public scrutiny and discontent.
