Social ties play a fundamental role in cohesion and collective action in contemporary societies. However, a significant portion of these ties emerges through informal and cultural forms that are often difficult to analyze within conventional theoretical frameworks. In the literature on social capital, most approaches focus on institutional structures and formal participation, while soft and context-based relationships have received less attention. This study aims to provide a theoretical explanation of the concept of fluid social capital within the framework of intangible cultural heritage by identifying and analyzing the soft ties that evolve in ritualistic, symbolic, and lived spaces—ties that have the potential to transform into mechanisms of trust, cohesion, and social engagement.To address the central research question—How does fluid social capital manifest through soft ties in cultural contexts?—this research adopts a mixed-methods approach (qualitative–quantitative) in three stages. In the qualitative phase, through comparative content analysis of theoretical texts and the use of MAXQDA software, four core components were identified: social trust, social participation, cultural memory, and contextual dynamics. In the quantitative phase, these qualitative concepts were converted into measurable indicators and, through the use of Geographic Information Systems (GIS) and Kernel Density Estimation, conceptual maps were generated to illustrate the distribution and intensity of these components within cultural spaces. Findings indicate that soft ties, despite their apparent instability, possess meaningful structures. Hence, fluid social capital necessitates a reevaluation of conventional theories and encourages interdisciplinary approaches to better comprehend the cultural complexities of informal contexts.
