Argentina occupies a paradoxical position in the comparative literature on trust: a country with one of Latin America's oldest continuous democratic periods since 1983, yet one whose citizens report chronically low confidence in one another and in the state. This article presents a narrative literature review of empirical and theoretical scholarship on interpersonal, institutional, and political trust in Argentina, drawing on Latinobarómetro survey data, World Values Survey findings, and peer-reviewed studies indexed on Google Scholar. The review traces four interlocking patterns. First, generalized interpersonal trust in Argentina, while comparatively higher than the regional Latin American average in recent survey rounds, remains low by global standards and has been shaped by decades of recurrent economic crisis. Second, institutional and political trust has followed a long-run downward trajectory punctuated by short-lived recoveries around new administrations, with a persistent gap between broad normative support for democracy and specific satisfaction with its performance. Third, this erosion is driven by an interacting cluster of factors: entrenched corruption and high-profile prosecutions of political elites, recurrent monetary and economic crises that have produced a durable narrative of monetary distrust, income inequality, and a closed political elite characterized by high incumbency and family-based succession. Fourth, Argentina's deep political polarization, commonly referred to as "la grieta" (the crack), both reflects and reinforces the erosion of generalized institutional trust. The review also considers how the COVID-19 pandemic and the 2023 election of Javier Milei illustrate the practical stakes of this trust deficit, and it identifies gaps in the literature that future longitudinal and comparative research should address.
