This stuff is all well documented mainstream sociology. The fact that you aren't aware of it and are reflexively defensive about it doesn't change that.
Mainly, I worry that in the professional world, getting branded as nice makes me less likely to receive recognition for being good at my job.
Conversely, women who get noticed for their high performance and technical skills are often viewed with suspicion and resentment. They may be denied opportunities to advance at work because they’re seen as lacking the people skills necessary for leadership roles. And if they do manage to get promoted, they’re likely to be deemed difficult.
This puts women in a maddening double bind: Is it better to seem nice and be underestimated, or to seem smart and be disliked? Carly Fiorina, the former head of Hewlett-Packard and 2016 Republican presidential candidate, summarized one version of this paradox in her 2006 memoir, writing that throughout Silicon Valley, during her tenure at HP and long after, “I was routinely referred to as either a bimbo or a bitch.”
Conflating warmth and weak performance puts women at a disadvantage. And it has big ramifications for everyone else, too. Kindness, because it is a quality that’s closely linked with stereotypical femininity, has been systematically devalued in contemporary office cultures and in American culture more broadly. This misconception has made our workplaces, and our society, less functional, less moral, and ultimately, less human.
