As a doctoral candidate in the social sciences more than 20 years ago, Duana Welch, 49, had done enough research to know the consequences she'd face by reporting sexual harassment in the workplace.
"When women came forward with allegations of sexual abuse and sexual harassment, the woman was the person blamed and the woman was not believed," she said. "I was very angry that I would pay the price for coming forward. I knew what would happen."
Like most who've had similar experiences, Welch, a relationship expert in Eugene, Ore., kept quiet. She wanted to bury the inappropriate encounters initiated by men who outranked her in the workplace. Welch worried that her fledgling career would be doomed.
That was until #MeToo.
"I jumped in immediately," she said. "I knew that this was our moment. It was the first time I became very public about abuses and inappropriate sexual conduct that I've experienced."
But figuring out why Welch and the millions who have posted on social media using #MeToo isn't as simple as chalking it up to the power of the hashtag. Rather, a complex set of psychological and sociological factors is at work. Sparked by revelations about Hollywood titan Harvey Weinstein, the mushrooming list of accused harassers and those unwilling to stay silent any longer illustrates that what's happening with this avalanche of disclosures is more than just a show of strength in numbers.
"Admissions of being a victim are stigmatizing," said John Pryor, a professor of psychology emeritus at Illinois State University who has studied sexual harassment for more than 30 years and is participating in a National Academy of Sciences study of sexual harassment in STEM fields — science, technology, engineering and mathematics.
"Research has shown that people with stigmatizing conditions that can be hidden often engage in what is called 'label avoidance.' With regard to sexual harassment, the more people who come forward and say 'me, too,' the less stigmatizing the label," he said.
