This chapter critically examines the detrimental effects of New Thought principles in healthcare. It highlights how these beliefs can lead to victim-blaming and stigmatization of patients whose conditions worsen despite maintaining a positive mindset, with a specific focus on cancer patients who face emotional distress exacerbated by military metaphors equating illness to a battle. While some level of optimism may be beneficial, the chapter argues that excessive positivity can distort individuals’ perceptions, leading to overconfidence and poor decision-making, ultimately affecting health outcomes. The New Thought ideology implies that success stems solely from individual willpower, neglecting the influence of systemic inequalities and social determinants on health. To address these issues, a more nuanced perspective is necessary—one that balances personal agency with a recognition of external factors and advocates for structural changes to rectify health disparities rather than imposing undue blame on individuals for their circumstances.
