In this chapter, the author lays the foundations to a new debate about risk perception and the securitization process within the constellations of tourism fields. The chapter represents not only a critical insight on the already-established paradigms but also to the ethnocentrism of English-speaking scholars who have developed an economic-based paradigm of risk perception. The chapter explores the dichotomies and differences among risk, threat, danger, security, and fear while gives a new fresh insight to forge a new sub discipline in tourism: the anthropology of tourism security. While the economic-based theories enthusiastically accept quantitative-related methods, this position reached a state of stagnation. Qualitative-led methodologies as ethnography and analysis content would fill the gap in the years to come. Today, the emergence of some alternative theories as post disaster or post-conflict theories evinces that the doctrine of precautionary principles rested on shaky foundations.
