The Shadow Self Online examines how algorithms shape identity, behavior, and belief in the digital age. Drawing on research from psychology, sociology, philosophy, and technology studies, JR Sellers explores the emergence of an "algorithmic self"-a predictive digital reflection that increasingly influences attention, autonomy, and collective reality.Written for academics, educators, and critical thinkers, this book analyzes the psychological consequences of algorithmic design, the societal collapse of shared truth, the erosion of free will, and the future of meaning in a world driven by data. With a multidisciplinary approach, Sellers offers a rigorous yet accessible framework for understanding how digital environments reshape individuals and communities-and proposes a human-centered path forward for a post-algorithmic society.
