Philosophy Of Pseudoscience by Massimo Pigliucci

Reconsidering the Demarcation Problem

This book examines the longstanding problem of distinguishing science from pseudoscience, surveying historical and philosophical attempts to draw a demarcation line, critiquing simple criteria like naïve falsifiability, and arguing for a nuanced mixture of methodological, evidential, and sociological markers such as testability, empirical support, openness to revision, and integration with established knowledge; it uses case studies (e.g., creationist and paranormal claims) to show how cognitive biases, motivated reasoning, and poor methodological practices sustain pseudoscientific beliefs, and it emphasizes the importance of critical thinking, science education, and institutional norms in defending reliable scientific inquiry.
