Von der englischen Wikipedia-Seite (anscheinend gibt es keine deutsche Seite dazu) ueber das Buch von John Gray, "Men Are from Mars, Women Are from Venus":
The book has been criticized for placing human psychology into stereotypes. 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 2004 a Purdue University communications 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. That isn't what most men do, and it isn't good for either men or women."
Michael Kimmel, a professor of Sociology at Stony Brook University, further supports the assertion that men and women are not fundamentally different, contrary to what Gray suggests in his book. He also challenges Gray’s premise that all men are essentially the same, and that all women are essentially the same. 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. Furthermore, Kimmel argues that there is greater variation within the gender categories of men and women than there is between men and women.
Kimmel supports this claim that women and men are socially and politically alike by tracking some of the historical changes women have gone through in the generations leading up to the present. Through developments such as co-education, the acknowledgement of gender as a master status, the increasing presence of women in the workforce, and the sexual revolution, Kimmel argues that women and men today have many of the same social and political concerns. These include political concerns such as parental leave, on-site childcare, and flexible work hours, and social concerns such as entitlement to pleasure.
Kimmel concludes his argument by suggesting that men begin to take accountability in areas traditionally labeled as ‘women’s issues’ such as rape culture, safe sex practices, and other areas commonly considered gender specific, and considers men’s involvement in these issues imperative if they are to be properly addressed. He contends that, contrary to Gray’s argument, men and women are not fundamentally different, and share common social and political goals.
A study by Bobbi Carothers and Harry Reis involving over 13,000 individuals claims that men and women generally do not fall into different groups. "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,"
