He previously worked as an assistant and an associate professor in the psychology department at Harvard University.
On September 27, 2016, Peterson released the first installment of a three-part lecture video series, entitled "Professor against political correctness: Part I: Fear and the Law". In the video, he stated he would not use the preferred gender pronouns of students and faculty, and announced his objection to the Canadian government's Bill C-16, which proposed to add "gender identity or expression" as a prohibited ground of discrimination under the Canadian Human Rights Act, and to similarly expand the definitions of promoting genocide and publicly inciting hatred in the Criminal Code.
Two months later, the National Post published an op-ed by Peterson in which he elaborated on his opposition to the bill and explained why he publicly made a stand against it:He politically identifies as a classic British liberal He is a philosophical pragmatist. By religious beliefs, he is a Christian, but with agnostic elements and viewpoints similar to the Christian existentialism and philosophy of Søren Kierkegaard and Paul Tillich, as well as influence by Carl Jung. He has stated his respect for the teachings of Taoism, as it "sees nature as a constant battle between order and chaos, and posits that without that struggle, life would be rendered meaningless"
