[6] On 16 May 2024, Manne and David Livingstone Smith of the University of New England were awarded the Lebowitz Prize by Phi Beta Kappa and the American Philosophical Association for an as yet unpublished presentation titled "Dehumanization and its Discontents".

[7][8] Manne has written articles in moral philosophy and metaethics, as well as three books, Down Girl: The Logic of Misogyny (2017),[9] Entitled: How Male Privilege Hurts Women (2020),[10] and Unshrinking: How to face Fatphobia (2024).

"[13] Manne coins the term "himpathy", which she defines as "the inappropriate and disproportionate sympathy powerful men often enjoy in cases of sexual assault, intimate partner violence, homicide and other misogynistic behavior".

[16] Nesrine Malik of The Guardian praised it, writing, "with perspicacity and clear, jargon-free language, Manne keeps elevating the discussion to show how male privilege isn't just about securing and hoarding spoils from women, but an entire moral framework.

Berg also questioned Manne's "perception of continuity from mansplainer to murderer" and compared her pessimism and her injunction not to bother trying to convince those who are not already "of a similar mind" to the attitudes expressed on incel forums.

[18] Manne's 2024 book Unshrinking: How to Face Fatphobia is a history of the stigmatization of fat people in the workplace, at school, relationships, and in healthcare.
