After the gang rape of a young Indian woman in Delhi in 2012 — a victim now known in India as “Nirbhaya,” which means “Fearless” in Hindi — protestors marched in the Indian capital, candlelight vigils were held and courts sentenced the rapists to death.

Deepa Narayan, a sociologist based in Delhi, kept turning one question over and over in her head: How did Indian society come to accept this treatment of women?

The question led Narayan and her researchers to conduct 600 interviews — about 3,000 hours over three years, documented in more than 8,000 pages of notes, now published in a new book called “Chup," the Hindi word for the imperative “Quiet.”

Her research, conducted in the country’s major cities, reveals that India’s young, educated, modern women still encounter widespread gender inequality, and often internalize conservative attitudes toward women’s social roles.

Women, even those who said they were feminists, often used words such as “mother,” “sacrifice” or “giving” to describe themselves, Narayan found, while men often described themselves as a “leader” or “powerful.”

India, despite making strides in development in the past three decades, lags behind on gender equality. It ranks 131 of 188 countries on the U.N. Development Program’s Gender Inequality Index.

Dowry, female infanticide and women’s education are persistent issues despite decades of successive governments’ efforts to address them. Narayan said the problems in India are not limited to villages and uneducated people.

Narayan didn’t expect that so many of her interviewees — a sample of India’s young, modern women — would be parroting female stereotypes, despite labeling themselves as feminists. “What I heard women saying was disturbing. Over and over I would shake my head in disbelief that yet another smart and smartly dressed woman, an artist, a business manager, a financial analyst, a professor, a dentist, an engineer, a lawyer, a researcher, a scientist, a teacher, an educated stay-at-home mom was so unsure of herself.

“Society is stagnating under the veneer of modernity,” Narayan said. “Women have internalized these behaviors that make it so men continue to be in power.”

Many women described being groped — almost all of Nayaran’s women interviewees, she said, had experienced being inappropriately touched. “This has become normalized. This is no longer traumatic,” she said.

Such behaviors occur because of how young girls in India are raised, Narayan writes. “I call the way girls are raised ‘fear training,’ literally, training girls to become fearful. It is training based on no and don’t. No, you can’t do this. No, you can’t do that.”

The portraits Narayan depicts are ones that many Indian women will recognize — one woman describes her husband forcing her to sign a resignation letter the day after her marriage, another describes her mother’s anger on learning she was a lesbian, despite being a gender-training expert.

Male interviewees, too, Narayan said, suggested how women’s roles in society are perceived differently from men’s. One man for instance described his father as an intellectual with whom he could have long debates, and his mother as simply “superstitious.” “He called his mother the ‘shock absorber,’ ” Narayan said. “She absorbs all the tension and keeps the peace.”
