Worldviews can serve as a resource or an obstacle when navigating intellectual and existential challenges encountered in life. My objective in this article is to identify and analyse the various ways in which people’s worldviews can shift, break down, evolve, or be strengthened by their life experiences. The proposed model of worldview formation identifies five outcomes that an encounter with what I refer to as existentially significant life events can have: worldview compartmentalisation, integration, revision, conversion, and confirmation. I will explain the content and function of these categories, provide concrete examples, and discuss their rationality.
