Gad Saad (born 1964) is a Lebanese-Canadian evolutionary behavioural scientist at the John Molson School of Business (Concordia University, Montreal, Quebec, Canada) who is known for applying evolutionary psychology to marketing and consumer behaviour.[1] He holds the Concordia University Research Chair in Evolutionary Behavioural Sciences and Darwinian Consumption (2008–2018)[2] and has a blog at Psychology Today titled Homo Consumericus.[3]


Early life and education[edit]

Saad was born in 1964 in Beirut, Lebanon, to a Jewish family. His family fled to Montreal, Quebec, Canada in October 1975 to escape the Lebanese Civil War.[4] He obtained a B.Sc. (Mathematics and Computer Science) and M.B.A. from McGill University, and an M.S. and Ph.D. from Cornell University.[5] Saad's doctoral adviser was the mathematical/cognitive psychologist and behavioural decision theorist Edward Russo.

Career and research[edit]

Saad has been a professor of marketing at Concordia University since 1994. During this time he has also held visiting professorships at Cornell University, Dartmouth College, and the University of California, Irvine.[6] He is associate editor for the journal Evolutionary Psychology, and an advisory fellow for the Centre for Inquiry Canada.

One line of research that Saad has been exploring is how hormones affect consumers and the decisions they make. Examples of this research include how showy products affect testosterone levels,[7][8] how testosterone levels affect various forms of risk-taking,[9][10][11] and how hormones in the menstrual cycle affect buying decisions.[12][13] Another line of research has involved gift giving, including how men and women differ in why they give.[14][15][16][17]
