Jordan Peterson, the controversial Canadian psychology professor who has become internationally famous by denouncing feminism and other social justice issues, has posted a photo on his Instagram account of himself in the studio with members of Mumford & Sons, as the Quietus points out. The picture was published in May but recently circulated on Twitter. Pitchfork has reached out to the band’s representatives for comment.

Peterson, who believes that white privilege is a “Marxist lie” and refuses to acknowledge gender-neutral pronouns, is a clinical psychologist and a professor of psychology at the University of Toronto. With the rise of the so-called alt-right, he has become a figurehead of the reactionary backlash against feminism, political correctness, gender self-identification, and other issues. In a New York Times interview published in May, Peterson made the case for "enforced monogamy” as a corrective against male violence. (Peterson's photo with Mumford & Sons was posted two days before the New York Times interview was published.)

As his YouTube videos amass millions of views, various writers and public figures have denounced him as dangerous and bigoted. He has also received support from musicians including Sean Ono Lennon and Laetitia Sadier.
