They may be big fans of the show, but some sociologists are calling out historical inaccuracies in AMC’s “Mad Men.” According to the Pittsburgh Post-Gazette:

“As historians, most of us just love ‘Mad Men’ — it is so realistic, not just in the details, but in the gender dynamics,” said Stephanie Coontz, a sociologist and professor at Evergreen State College in Olympia, Wash. “But, I think in this case they’ve gotten it wrong.”

Discovering Don was not the man she thought she knew was merely the last straw for Betty, who surely suspected her husband’s many dalliances. So she began a flirtatious relationship with Henry Francis, a well-placed aide to Nelson Rockefeller, the governor of New York.

Henry flew with her to Nevada, where “divorce mills” of the day allowed (mostly) women to establish residency for six weeks, then file for divorce.

But Ms. Coontz, who has authored a number of books examining American life and family, said she doubts someone like Henry would have considered courting a married woman with three young children.

“In 1964, Nelson Rockefeller could not run for president because he was divorced — anyone with high aspirations, unless he was absolutely besotted with love, would never have considered getting involved in a divorce.”

Another sociologist adds:

Christine B. Whelan is visiting assistant professor at Pitt, where she is teaching three classes on the sociology of marriage, gender and everyday life, respectively.

Her American Family course at the University of Iowa last year made occasional reference to “Mad Men,” but to her dismay, the students couldn’t relate.

“I said ‘Listen guys, I’m going to make this required viewing,’ ” Dr. Whelan said, laughing.

A divorced woman in 1963 was a social pariah, she said, but noted that the Drapers are not meant to be viewed as an average couple in average America. “It’s emblematic of a very small slice — not only does Betty get out of her [bad] marriage, she has another man all lined up.”

But the show doesn’t get it all wrong:

One thing “Mad Men” gets right is the neighborhood ladies’ opinion of Helen, an attractive, young divorced mother of two introduced in the first season.

“She is this dangerous creature, and the other women view her as a threat,” Dr. Whelan said.

And:

Ms. Coontz has a new book coming out based on interviews with women who read Betty Friedan’s iconic 1963 writings when they were young — “A Strange Stirring: ‘The Feminine Mystique’ and American Women at the Dawn of the 1960s.”

“People say feminists hurt the homemaker, but one of the first reforms was marriage,” she said. In “Mad Men,” “You can see Betty already grappling with the same malaise that my real-life informants went through.”

In season one, Betty realizes while driving the car that she cannot feel her hands.

“Early in the show, her hands go numb, numb just like the 188 women I interviewed for this book who thought, ‘I was crazy,’ or just felt numb. They couldn’t express it, this emptiness and despair.”

Ms. Coontz came across a Gallup poll from December 1962, that indicated American housewives were happy with their lives, but 90 percent said they would advise their daughters to delay marriage and work at a job first.
