Huge Gender Bias Found in Hiring - New Study | Scott Adams Blog: "CNN reports on a new study showing there is a HUGE gender bias in hiring decisions in the United States and it has been this way in some fields since the eighties. You already knew there was gender bias in hiring (duh) but you probably did not know how bad it was. Check this out: The gender preference in hiring decisions was 2-to-1 in some areas for candidates with equal qualifications.  That is an embarrassing number for a country that prides itself on equal opportunity. A 2-to-1 advantage is not even within driving distance of equal rights...

I’m not sure if I mentioned that the study shows the gender advantage in hiring favors women by 2-to-1."

The myth about women in science - CNN.com: "The prevailing wisdom is that sexist hiring in academic science roadblocks women's careers before they even start. The American Association of University Professors and blue-ribbon commissions attest to this. An influential report by the National Academy of Sciences in 2006 concluded that "on the average, people are less likely to hire a woman than a man with identical qualifications," and noted that scientists and engineers "are not exempt." Wendy M. Williams Stephen J. Ceci Many female graduate students worry that hiring bias is inevitable. A walk through the science departments of any college or university could convince us that the scarcity of female faculty (20% or less) in fields like engineering, computer science, physics, economics and mathematics must reflect sexism in hiring. 

But the facts tell a different story. National hiring audits, some dating back to the 1980s, reveal that female scientists have had a significantly higher chance of being interviewed and hired than men. Although women were less likely to apply for jobs, if they did apply, their chances of getting the job were usually better...

When we searched the literature, we could not find one empirical study of sexism in faculty hiring using actual faculty members as evaluators and focusing on fields in which women are most underrepresented. So we did the study ourselves (published this week in the Proceedings of the National Academy of Sciences), testing 873 faculty members at 371 institutions in 50 states. To tease out sex bias, we created fictional candidate profiles identical in every respect except for sex, and asked faculty to rank these candidates for a tenure-track job...

We ran five national experiments with these otherwise-identical female and male candidates, systematically varying their personal attributes and lifestyles in a counterbalanced design. Every time we sent a given slate of candidates to a male faculty member, we sent the same slate with sexes reversed to another male faculty member, as well as sending both slates to two female faculty members. Then we compared the faculty members' rankings to see how hirable each candidate was, overall. What we found shocked us. Women had an overall 2-to-1 advantage in being ranked first for the job in all fields studied. This preference for women was expressed equally by male and female faculty members, with the single exception of male economists, who were gender neutral in their preferences.  In some conditions, women's advantage reached 4-to-1. When women were compared with men who shared the same lifestyle, advantages accrued to women in all demographic groups—including single or married women without children, married women with preschoolers, and divorced mothers."
