In Jack Mezirow’s Transformative Learning Theory, what primary catalyst or triggering event compels an adult learner to critically examine and re-evaluate their fundamental assumptions, worldviews, and deeply held beliefs?

Jack Mezirow’s Transformative Learning Theory focuses on how adult learners construct meaning from their experiences and transform their established frames of reference (meaning perspectives, mindsets, and core assumptions). The Role of the "Disorienting Dilemma": The Catalytic Event: Transformative learning typically begins with a disorienting dilemma—an acute experience, crisis, or challenge that cannot be resolved or understood using the individual's existing knowledge, assumptions, or problem-solving habits. Cognitive Dissonance & Reflection: This dilemma creates cognitive dissonance, prompting self-examination, critical reflection on underlying assumptions, exploration of new roles or options, and ultimately a transformation in how the individual perceives themselves and the world.
