Gad Saad

Gad Saad is a Lebanese-born Canadian professor of marketing at Concordia University's John Molson School of Business, specializing in evolutionary behavioral sciences and the application of evolutionary psychology to consumer behavior and decision-making. He held the Concordia University Research Chair in Evolutionary Behavioral Sciences and Darwinian Consumption from 2008 to 2018, during which he advanced research integrating Darwinian principles with marketing and psychology. Saad's academic output includes over 75 peer-reviewed publications, with key works exploring topics such as gift-giving, menstrual cycle influences on consumption, and evolutionary bases of economic behaviors, amassing thousands of citations in scholarly databases.

Beyond academia, Saad has gained prominence as a public intellectual critiquing ideologies such as postmodernism and identity politics, which he describes as "parasitic ideas" or "idea pathogens" that he argues spread like infectious diseases and undermine empirical reasoning and institutional integrity, particularly in universities, which he argues exhibit left-leaning biases and suppress dissenting views. His 2020 book The Parasitic Mind: How Infectious Ideas Are Killing Common Sense argues that certain ideologies, which he describes as "idea pathogens" or "parasitic ideas," spread like infectious diseases and undermine rational thinking and common sense. The book became a bestseller and has contributed to discussions on free speech and intellectual freedom. Other publications, including The Consuming Instinct (2011), extend his evolutionary framework to everyday human motivations. Saad hosts The Saad Truth podcast, where he analyzes scientific and societal issues with what he describes as data-driven analysis, often addressing topics such as radical Islamism and cancel culture.

Gad Saad was born on October 13, 1964, in Beirut, Lebanon, to a family of both Lebanese Jewish and Syrian Jewish descent, part of one of the last remaining Jewish communities in the country, which had dwindled significantly by the mid-20th century due to emigration and rising tensions. His parents were well-integrated into Lebanese society prior to the escalation of sectarian conflicts.

Saad has described his childhood as marked by pervasive antisemitism, including routine hostility toward Jews, which his family attributed to broader societal undercurrents in Lebanon at the time. He later described these experiences as embedding a deep awareness of existential threats from an early age. This environment, marked by the presence of Jewish roots tracing back to Syria, shaped early experiences amid a pluralistic but increasingly volatile national fabric.

The family's refusal to emigrate despite rising tensions continued until the outbreak of the Lebanese Civil War in April 1975 when Saad was 10 years old. He witnessed the initial violence, including the first year of fighting that killed tens of thousands and involved sectarian clashes, Palestinian militias, and Syrian intervention, until he was 11. The escalating dangers—amid a conflict that displaced over a million people and destroyed much of Beirut—prompted a permanent departure in 1975, though his parents kept returning to Lebanon periodically. On one of their return trips around 1980, they were kidnapped by Fatah. The family immigrated as refugees to Montreal, Quebec, Canada, where Saad adapted to a new cultural and linguistic environment, already speaking French but learning English while grappling with the trauma of displacement. These experiences, including the abrupt shift from war-torn Beirut to a Western society, gave him, as he has stated, a firsthand appreciation for the fragility of civilized order and the costs of ideological extremism. Less than two years after arrival, in 1977, his parents enrolled him in Camp B'nai Brith, a Jewish summer camp, which reinforced his Jewish identity amid the challenges of integration.
