A critical element that is often overlooked when studying negotiations in civil wars is popular support for the peace process itself. This is particularly important when agreements are subject to ratification by the broader population, as was the case in the Colombian conflict with the FARC. Using survey data from 2014, we find that attitudes toward this peace process were driven by political preferences more than conflict experiences. Some demographic traits (education, religion, and rural residency) were also important. Notably, these determinants of support for talks with the FARC map closely onto voting patterns in the October 2016 plebiscite.
