Women Choose Their Destinies in Science

Since 1970, women have made dramatic gains in science. Today, half of all MD degrees and 52% of PhDs in life sciences are awarded to women, as are 57% of PhDs in social sciences, 71% of PhDs to psychologists, and 77% of DVMs to veter-inarians.* Forty years ago, women’s presence in most of these fields was several orders of magnitude less; e.g., in 1970 only 13% of PhDs in life sciences went to women (1). In the most math intensive fields, however, women’s growth has been less pronounced (2–4). Among the top 100 US universities, only 8.8–15.8% of tenure-track positions in many math-intensive fields(combined across ranks) are held by women, and female fullprofessors number ≤10%. _PNAS Ceci, Williams
Famous Women in Science
Is the relatively low number of women professors in math-intensive fields due to discrimination, or do women choose their destinies in their field of choice? A recent study published in PNAS suggests that the choice depends on the woman, and how she interprets her ensemble of personal and professional needs.
It's not discrimination in instances of different hiring, but rather differences in resources attributable to career and family-related choices that set women back in science, technology, engineering and math (STEM) fields, say Stephen J. Ceci, professor of developmental psychology, and Wendy M. Williams, professor of human development and director of the Cornell Institute for Women in Science, both in Cornell's College of Human Ecology.

The "substantial resources" universities expend to sponsor gender-sensitivity training and interviewing workshops would be better spent on addressing the real causes of women's underrepresentation, Ceci and Williams say, through creative problem-solving and policy changes that respond to differing "biological and social realities" of the sexes.

The researchers analyzed the scientific literature in which women and men competed for publications, grants or jobs in these fields. They found no systematic evidence of sex discrimination in interviewing, hiring, reviewing or funding when men and women with similar resources – such as teaching loads and research support – were compared.

"We hear often that men have a better chance of getting their work accepted or funded, or of getting jobs, because they're men," Williams said. "Universities expend money and time trying to combat this rampant alleged discrimination against women in the hope that by doing so universities will see the numbers of women STEM scientists increase dramatically over coming years."

The data show that women scientists are confronted with choices, beginning at or before adolescence, that influence their career trajectories and success. Women who prioritize families and have children sometimes make "lifestyle choices" that lead to them to take positions, such as adjunct or part-time appointments or jobs at two-year colleges, offering fewer resources and chances to move up in the ranks. _WomenInScience
From the abstract to the study:
Explanations for women's underrepresentation in math-intensive fields of science often focus on sex discrimination in grant and manuscript reviewing, interviewing, and hiring. Claims that women scientists suffer discrimination in these arenas rest on a set of studies undergirding policies and programs aimed at remediation. More recent and robust empiricism, however, fails to support assertions of discrimination in these domains. To better understand women's underrepresentation in math-intensive fields and its causes, we reprise claims of discrimination and their evidentiary bases. Based on a review of the past 20 y of data, we suggest that some of these claims are no longer valid and, if uncritically accepted as current causes of women's lack of progress, can delay or prevent understanding of contemporary determinants of women's underrepresentation. We conclude that differential gendered outcomes in the real world result from differences in resources attributable to choices, whether free or constrained, and that such choices could be influenced and better informed through education if resources were so directed. Thus, the ongoing focus on sex discrimination in reviewing, interviewing, and hiring represents costly, misplaced effort: Society is engaged in the present in solving problems of the past, rather than in addressing meaningful limitations deterring women's participation in science, technology, engineering, and mathematics careers today. Addressing today's causes of underrepresentation requires focusing on education and policy changes that will make institutions responsive to differing biological realities of the sexes. Finally, we suggest potential avenues of intervention to increase gender fairness that accord with current, as opposed to historical, findings. _PNAS
People tend to do what they are good at. A great deal of research demonstrates that at the most elite levels of math performance men outnumber women by as much as 7 to 1 or higher. Not only do math-proficient women tend to find themselves badly outnumbered by men in fields which are math intensive, but the higher testosterone levels of men in those fields tends to drive them to work harder over longer hours in order to achieve success -- even at the sacrifice of the men's personal and family lives. For men, it is a biological imperative to compete and excel.

For many women who happen to be good at math, other motivations and needs take precedence over the academic rat race. For women in fields dominated by other women -- such as psychology -- the competition is against other women who have lower testosterone levels like themselves. Stress levels are consequently not as high in terms of competitive performance anxiety -- although staff meetings may occasionally take on the ambience of a screeching cat fight. ;-)
Women who prioritize families and have children sometimes make “lifestyle choices” that lead to them to take positions, such as adjunct or part-time appointments or jobs at two-year colleges, offering fewer resources and chances to move up in the ranks. These women, however, are not held back by sex discrimination in hiring or in how their scholarly work is evaluated. Men with comparably low levels of research resources fare equivalently to their female peers. Although women disproportionately hold such low-resource positions, this is not because they had their grants and manuscripts rejected or were denied positions at research-intensive universities due to their gender.

Also, females beginning before adolescence often prefer careers focusing on people, rather than things, aspiring to be physicians, biologists and veterinarians rather than physicists, engineers and computer scientists. Efforts to interest young girls in these math-heavy fields are intended to ensure girls do not opt out of inorganic fields because of misinformation or stereotypes.

Also, fertility decisions are key because the tenure system has strong disincentives for women to have children — a factor in why more women in academia are childless than men. Implementation of “flexible options” to enhance work-family balance may help to increase the numbers of women in STEM fields, the researchers say. _SB
Women should be free to choose the nature of their careers, and not be pushed into career tracks which they feel do not suit them, by political feminists.

There is far too much denial of human biodiversity (HBD) inside politics, the media, and the academy. By denying the natural statistical diversity of human biology in the genders and other population groupings, these HBD deniers do untold amounts of damage to generation after generation of young people -- and to society at large.

Is Wikimedia Dumbing Down the Idiocracy?

NYT

Several areas of commerce, enterprise, and science remain the province of mainly-male participation. Physics, mathematics, advanced computer science, technical engineering, math-intensive sciences, aircraft test pilots and combat pilots, commercial sea captains, and so on. Most informed people understand that research is dominated by males, but few people realise that technical information intensive areas -- such as highly demanding reference information providers -- are also dominated by males. A lot of politically involved feminists would like to change that situation, but is there a danger in moving too forcefully from the top down when changes may adversely affect critically important services?
...surveys suggest that less than 15 percent of [Wikipedia's] hundreds of thousands of contributors are women.

About a year ago, the Wikimedia Foundation, the organization that runs Wikipedia, collaborated on a study of Wikipedia’s contributor base and discovered that it was barely 13 percent women; the average age of a contributor was in the mid-20s, according to the study by a joint center of the United Nations University and Maastricht University.

...The notion that a collaborative, written project open to all is so skewed to men may be surprising. After all, there is no male-dominated executive team favoring men over women, as there can be in the corporate world; Wikipedia is not a software project, but more a writing experiment — an “exquisite corpse,” or game where each player adds to a larger work.

...The public is increasingly going to Wikipedia as a research source: According to a recent Pew survey, the percentage of all American adults who use the site to look for information increased to 42 percent in May 2010, from 25 percent in February 2007. This translates to 53 percent of adults who regularly use the Internet.

Jane Margolis, co-author of a book on sexism in computer science, “Unlocking the Clubhouse,” argues that Wikipedia is experiencing the same problems of the offline world, where women are less willing to assert their opinions in public. “In almost every space, who are the authorities, the politicians, writers for op-ed pages?” said Ms. Margolis, a senior researcher at the Institute for Democracy, Education and Access at the University of California, Los Angeles.

...Ms. Gardner said that for now she was trying to use subtle persuasion and outreach through her foundation to welcome all newcomers to Wikipedia, rather than advocate for women-specific remedies like recruitment or quotas.

“Gender is a huge hot-button issue for lots of people who feel strongly about it,” she said. “I am not interested in triggering those strong feelings.”

Kat Walsh, a policy analyst and longtime Wikipedia contributor who was elected to the Wikimedia board, agreed that indirect initiatives would cause less unease in the Wikipedia community than more overt efforts.

But she acknowledged the hurdles: “The big problem is that the current Wikipedia community is what came about by letting things develop naturally — trying to influence it in another direction is no longer the easiest path, and requires conscious effort to change.” _NYT
The Wikipedia world is indeed a rough and tumble world of competitive edits and re-writes. If a person cannot withstand criticism and competition, they will not likely last long in that world.

The male hormone testosterone shapes the human brain in multiple ways not yet fully comprehended by science or society at large. Much of what science has learned about the influence of hormones such as testosterone on the gender differences so prevalent in society, is considered not politically correct -- and thus essentially unmentionable in left-leaning tabloids such as the New York Times, quoted above. Testosterone makes males more interested in objects than people, more competitive, have generally superior spatial and higher math skills, physically larger and stronger with greater stamina, tending to greater independence, and generally more logically determined and less emotional in the face of distractions.

Charles Murray's fascinating book, Human Accomplishment, provides a historical reflection of the phenomenon that Wikimedia's executives and critics are struggling with. Males have tended to achieve the lion's share of discoveries, inventions, and masterpieces of art, music, and literature as far back as history can tell.

A population shrinkage is occurring among the more intelligent people of the world -- Europeans and Northeast Asians -- while an explosive growth of population is occurring among the less intelligent people of the world. The average intelligence of the human population is inexorably dropping from near 90 points of IQ, downward -- close to the mid-80s and below. That qualifies as an Idiocracy.

In order to dumb down the Idiocracy, one must institute foolish rules of arbitrary and counter-productive governance, while educating the populace to accept dumbed-down groupthink rather than to think for themselves. It is easier than you might think. What Wikimedia is contemplating -- and what many western governments have done, and called affirmative action -- is an excellent example.
