The episode explains psychological and neuroscience research showing novelty’s role in motivation, attention, learning, and memory (including locus coeruleus activation), the inverted-U relationship between complexity and curiosity, and how habituation can flatten engagement when stimuli stay too familiar. Poston contrasts this with the mere exposure effect (Zajonc) and processing fluency, arguing platforms reinforce and shape preferences through repeated exposure, producing “adjacent novelty” rather than true surprise. She links personalization to self-concept via the looking-glass self and self-perception theory, describing identity-shaping pipelines, and argues personalization reduces shared cultural overlap, contributing to epistemological fragmentation. Practical suggestions include turning off autoplay, browsing physical spaces, reading outside one’s interests, and holding preferences lightly to preserve room for the unexpected.\nVOTE HERE UNTIL APRIL 30th!
