After months of abuse and harassment from users, Reddit CEO Ellen Pao resigned from the website. Unfortunately, Pao’s experience is far from unique. Many female chief executives face character assassination based in large part on their gender; the anonymity of the Internet allows harassment to escalate as far as death threats. For many experts, Pao’s resignation is an example of the “glass cliff,” a point where women rise to higher positions only to be forced out through excessive personal attacks and abuse.

Sociologist Marianne Cooper of Stanford University’s Clayman Institute for Gender Research isn’t surprised by this gendered bias, telling The Guardian, “I haven’t seen this kind of reaction to egregious things male CEOs have done.”

As lead researcher for Lean In: Women, Work, and the Will to Lead, Cooper is familiar with the gendered biases of the workplace and the use of female leaders as scapegoats for larger company problems: “Oftentimes, the women who inherit the problems are put in precarious positions, and if they fail, they are blamed for it.”
