Parasitic Mind: How Infectious Ideas Are Killing Common Sense

Dive into a controversial and sharply argued critique of contemporary ideological trends with “Parasitic Mind” by Gad Saad — essential reading for readers interested in the intersection of evolutionary science, academic freedom, free speech, and the current state of Western intellectual culture.

Gad Saad is a professor of marketing at Concordia University who applies evolutionary psychology to understanding consumer behaviour and human nature, and in this book he turns that lens onto what he calls “idea pathogens” — ways of thinking that, in his view, suppress rational inquiry, undermine scientific standards, and spread through institutional systems in ways that are difficult to challenge without social or professional consequences. He argues against postmodern epistemology, certain applications of identity politics in academic settings, and what he sees as a growing reluctance in universities and media to engage honestly with empirical evidence that challenges preferred narratives. The book is unapologetically polemical — Saad does not write as a dispassionate observer — and many of his targets push back hard on both his characterisations and his conclusions. Readers are encouraged to engage critically and seek out responses to his arguments alongside the book itself.

Whether you are a scientist, an academic, a student concerned about intellectual freedom, or a general reader interested in debates about reason and ideology in contemporary culture, this is a combative and clearly argued entry point into a significant ongoing conversation.
