For decades, debates about gender and science have often assumed that women are more likely than men to “leak” from the science and engineering pipeline after entering college.
However, new research of which I am the coauthor shows this pervasive leaky pipeline metaphor is wrong for nearly all postsecondary pathways in science and engineering. It also devalues students who want to use their technical training to make important societal contributions elsewhere.
How could the metaphor be so wrong? Wouldn’t factors such as cultural beliefs and gender bias cause women to leave science at higher rates?
My research, published last month in Frontiers in Psychology, shows this metaphor was at least partially accurate in the past. The bachelor’s-to-Ph.D. pipeline in science and engineering leaked more women than men among college graduates in the 1970's and 80's, but not recently.
Men still outnumber women among Ph.D. earners in fields like physical science and engineering. However, this representation gap stems from college major choices, not persistence after college.
Other research finds remaining persistence gaps after the Ph.D. in life science, but surprisingly not in physical science or engineering -- fields in which women are more underrepresented. Persistence gaps in college are also exaggerated.
Consequently, this commonly used metaphor is now fatally flawed. As blogger Biochembelle discussed, it can also unfairly burden women with guilt about following paths they want. “It’s almost as if we want women to feel guilty about leaving the academic track,” she said.
Some depictions of the metaphor even show individuals funneling into a drain, never to make important contributions elsewhere.
In reality, many students who leave the traditional boundaries of science and engineering use their technical training creatively in other fields such as health, journalism and politics.
As one recent commentary noted, Margaret Thatcher and Angela Merkel were leaks in the science pipeline. I dare someone to claim that they funneled into a drain because they didn’t become tenured science professors. No takers? Didn’t think so.
Men also frequently leak from the traditional boundaries of science and engineering, as my research and other studies show. So why do we unfairly stigmatize women who make such transitions?
By some accounts, I’m a leak myself. I earned my bachelor’s degree in the “hard” science of physics before moving into psychology. Even though I’m male, I still encountered stigma when peers told me psychology was a “soft” science or not even science at all. I can only imagine the stigma that women might face when making similar transitions.
For this fellowship, I worked with two computer science graduate students and one bioengineering postdoc on a “big data” project for improving student success in high school. We partnered with Montgomery Public County Schools in Maryland to improve their early warning system. This system used warning signs such as declining grades to identify students who could benefit from additional supports.
This example shows why the leaky pipeline narrative is so absurd. Many leaks in the pipeline continue using their technical skills in important ways. For instance, my team’s data science skills helped improve our partner’s warning system, doubling performance in some cases.
Let’s abandon this inaccurate and pejorative metaphor. It unfairly stigmatizes women and perpetuates outdated assumptions.
Some have argued that my research indicates bad news because the gender gaps in persistence were closed by declines for men, not increases for women. However, others have noted how the findings could also be good news, given concerns about Ph.D. overproduction.
More importantly, this discussion of good news and bad news misses the point: the new data inform a new way forward.
By abandoning exclusive focus on the leaky pipeline metaphor, we can focus more effort on encouraging diverse students to join these fields in the first place. Helping lead the way forward, my alma mater -- Harvey Mudd College -- has had impressive success in encouraging women to pursue computer science.
Maria Klawe, Mudd’s first female president, led extensive efforts to make the introductory computer science courses more inviting to diverse students. For instance, course revisions emphasized how computational approaches can help solve pressing societal problems.
The results were impressive. Although women used to earn only 10 percent of Mudd’s computer science degrees, this number quadrupled over the years after Klawe became president. To help replicate these results more widely, we should abandon outdated assumptions and instead help students take diverse paths into science.
David Miller is an advanced doctoral student in psychology at Northwestern University. His current research aims to understand why some students move into and out of science and engineering fields.
Last year, two athletes at Erskine College, a Christian institution affiliated with the Associate Reformed Presbyterian Church, came out as gay. That news prompted antigay church members to demand that the college take action against gay people at the college. The college's board has now done so, adopting a policy saying that any sexuality that is not based on marriage (defined as between a man and a woman) is banned.
"We believe the Bible teaches that all sexual activity outside the covenant of marriage is sinful and therefore ultimately destructive to the parties involved. As a Christian academic community, and in light of our institutional mission, members of the Erskine community are expected to follow the teachings of Scripture concerning matters of human sexuality, and institutional decisions will be made in light of this position."
Outsports quoted one of the gay athletes as saying of the new policy: "It just made me sad and worried for other gay people who might be struggling with confidence to come out."
The board of East Carolina University voted Friday to remove the name of Charles Aycock, a former North Carolina governor who was for years a leader of the segregationist white supremacist movement in the state, from a dormitory (at right). Student and faculty groups have been pushing for the move. The university said that it would create a new Heritage Hall, in which contributions to the university by a number of individuals -- including Aycock -- could be acknowledged with context.
Wright State University has apologized for a menu last week to mark Black History Month. The Dayton Daily News reported that students complained that the menu, which featured fried chicken, collard greens and corn bread next to a photograph of the Rev. Dr. Martin Luther King Jr., reinforced stereotypes. Chartwells Higher Education Dining Services, which manages dining at Wright State and posted the menu, released a statement that said: "Chartwells celebrates many national events on campus and tries to provide authentic and traditional cuisine to reflect each theme. In no way was the promotion associated with Black History Month meant to be insensitive. We could have done a better job putting this in context of a cultural dining experience. We sincerely apologize.”
A new research collaborative was announced Thursday to promote academic study of efforts that promote success for minority boys and men. The effort is called RISE, for Research, Integration, Strategy and Evaluation. The codirectors are Shaun Harper of the University of Pennsylvania Graduate School of Education and Sharon Norris-Shelton of Equal Measure.
