In this episode of the Science Salon Podcast, Michael Shermer talks to the renowned evolutionary behavioral scientist and Concordia University professor Dr. Gad Saad. Starting with his escape to Canada from war-torn Lebanon, Dr. Saad recounts how he got interested in the study of human nature in general and consumer behavior in particular through the evolutionary lens, why people make the choices they do in the marketplace, why evolutionary psychology is an equal-opportunity offender to both the political left and right, what’s wrong with the Blank Slate model of human nature, what it means to hypothesize that something evolved “for” an adaptive reason, how evolutionary psychologists test their claims, the consilience of human knowledge, epistemological humility, postmodernism and how it has corrupted the academy, and the vital importance of free speech and free inquiry in science and society. Dr. Gad Saad held the Concordia University Research Chair in Evolutionary Behavioral Sciences and Darwinian Consumption from 2008 to 2018. He is the author of The Consuming Instinct (2011, Prometheus Books) and The Evolutionary Bases of Consumption (2007, Lawrence Erlbaum), editor of Evolutionary Psychology in the Business Sciences (2011, Springer), and is finishing his next book on idea pathogens and how they have spread like a contagion in the academy, now spilling out into government and corporations. He is the host of the popular podcast The Saad Truth, which focuses on science, religion, political correctness, multiculturalism, postmodernism, third-wave feminism, Islam, safe spaces, trigger warnings, and many other topics.
