Criticism of the book
The book has been criticized for placing human psychology into stereotypes.
Michael Kimmel, a professor of sociology at Stony Brook University, makes the assertion that men and women are not fundamentally different, contrary to what Gray suggests in his book. In Kimmel’s 2008 lecture at Middlebury College in Vermont, titled “Venus, Mars, or Planet Earth? Women and Men in a New Millennium”, Kimmel contends that the perceived differences between men and women are ultimately a social construction, and that socially and politically, men and women want the same things.
In 2002, author Julia T. Wood published a critical response to the portrayal of the genders in Men Are from Mars, Women Are from Venus . In the first chapter of 2003 book The Essential Difference , Simon Baron-Cohen compares with Gray’s bestseller and states: “the view that men are from Mars and women Venus paints the differences between the two sexes as too extreme. The two sexes are different, but are not so different that we cannot understand each other.” In 2004 Erina MacGeorge, a Purdue University communication professor, said that based on research she conducted using questionnaires and interviews, men and women are not so different and “books like John Gray’s Men are From Mars and Women are From Venus and Deborah Tannen’s You Just Don’t Understand tell men that being masculine means dismissing feelings and downplaying problems (which many men themselves that read the book disagree with). That isn’t what most men do, and it isn’t good for either men or women.”
A study by Bobbi Carothers and Harry Reis involving over 13,000 individuals found that on most psychological characteristics or tendencies, including the Big Five personality traits as well as sex-related questions like rating level of desire for casual sex, there was not a taxonomic difference between men and women on the vast majority of personality traits and preferences. Despite there being differences in averages by gender, the distributions overlapped so much that a taxonomy distinction was not meaningful. “Thus, contrary to the assertions of pop psychology titles like Men Are From Mars, Women Are From Venus , it is untrue that men and women think about their relationships in qualitatively different ways.” There were notable taxonomic differences on physical attributes and measurements of physical strength.
