A "social medium," within the context of understanding proposed by Iain McGilchrist, could be delineated as a conduit through which individuals engage in communication, exchange ideas, and form relationships, grounded in the intricate interplay between their embodied minds and the relational nature of their environments. It encapsulates more than mere data transmission; it reflects the subtleties and nuances of human interaction, bearing the imprint of the right hemisphere's propensity to perceive wholes and empathize. In an increasingly digitized world, social media platforms emerge as modern iterations, yet they often veer towards the left hemisphere's reductionist tendencies, potentially diminishing the depth and richness of interpersonal connections by focusing on quantifiable metrics. Consequently, a social medium is both a facilitator of human connection and a mirror to the dual hemispheric modes of engaging with the world—emphasizing the communal, intuitive, and experiential dimensions of our shared existence.
