Some authors have better described the phenome of Politically Correctness: Gustave Le Bon in the “The Crowd: A Study of the Popular Mind” which is considered one of the seminal works of crowd; Eric Hoffer in “The True Believer’ and Aldous Huxley or George Orwell in their dysantropic books from the 50`s .  An actual expert and writer of the PC-theme is Jordan Bernt Peterson He released in 2016 a series of videos on his YouTube channel in which he criticized political correctness and the Canadian government's Bill C-16.

According to Peterson, political correctness exists in two types: PC-egalitarianism and PC-authoritarianism, which is a manifestation of "offense sensitivity". He places classical liberals in the first type, and places so-called social justice warriors, who he says "weaponize compassion", in the second.

Peterson considers that the universities should be held as among the most responsible for the wave of political correctness which appeared in North America and Europe. He watched the rise of political correctness on campuses since the early 1990s and considers that the humanities have become corrupt, less reliant on science, and instead of "intelligent conversation, we are having an ideological conversation". From his own experience as a university professor, he states that the students who are coming to his classes are uneducated and unaware about the mass exterminations and crimes by Stalinism and Maoism, which were not given the same attention as Fascism and Nazism. He also says that "instead of being ennobled or inculcated into the proper culture, the last vestiges of structure are stripped from the students by post-modernism and neo-Marxism, which defines everything in terms of relativism and power".

Peterson states that postmodern philosophers and sociologists since the 1960s, started to play a sleight of hand, and instead of pitting the proletariat, the working class, against the bourgeois, they started to pit the oppressed against the oppressor. That opened up the avenue to identifying any number of groups as oppressed and oppressor and to continue the same narrative under a different name. The people who hold this doctrine – this radical, postmodern, communitarian doctrine that makes racial identity or sexual identity or gender identity or some kind of group identity paramount – they've got control over most low-to-mid level bureaucratic structures, and many governments as well". Some in the media have compared these critiques to Cultural Marxist conspiracy theories.
He emphasizes that the state should halt funding to faculties and courses he describes as neo-Marxist, and advises students to avoid disciplines like women's studies, ethnic studies and racial studies, as well other fields of study he believes are "corrupted" by the ideology such as sociology. He states that these fields, under the pretense of academic inquiry, propagate unscientific methods, fraudulent peer-review processes for academic journals, publications that garner zero citations, cult-like behaviour, safe-spaces, and radical left-wing political activism for students.

Peterson has proposed launching a website which uses artificial intelligence to identify and showcase the amount of ideologization in specific courses. He announced in November 2017 that he had temporarily postponed the project as "it might add excessively to current polarization".
Peterson has criticized the use of the term "white privilege", stating that "being called out on their white privilege, identified with a particular racial group and then made to suffer the consequences of the existence of that racial group and its hypothetical crimes, and that sort of thing has to come to a stop. ... It's racist in its extreme". In regard to identity politics, while "left plays them on behalf of the oppressed, let's say, and the right tends to play them on behalf of nationalism and ethnic pride" he considers them "equally dangerous" and that instead should be emphasized individualism and individual responsibility.
