Focusing on web-based platforms such as social media and online news, the book examines the role of active content creation and temporal dynamics in reinforcing existing beliefs and perpetuating cognitive feedback loops. Through original research and case studies, it highlights the interplay between algorithmic curation, participatory engagement, and misinformation spread in online spaces. This book fills a critical gap in research on the psychological mechanisms underlying bias formation in the digital age. It provides insights for tech leaders, media experts, and policymakers seeking to understand and mitigate the cognitive and societal impact of online information processing. By bridging the fields of cyberpsychology, media studies, and artificial intelligence, it offers strategies for fostering more balanced digital ecosystems.
