Stereotype Threat and the Gender Disparity in Science

There should be no doubt to anyone in the sciences that there is a “gender gap” in the sciences: there are fewer female professors than male professors in most scientific disciplines.  The degree varies across scientific disciplines, I’ve found it strongest in physics, and weakest in math, psychology and biology, but it’s always there and in the same direction.  A recent study shows that the problem is related to women’s perceptions of operating stereotypes in their colleagues: when women perceive that they will be judged as inferior, they often behave in such a way that reinforces the stereotype.  This reminds me of a now-classic study that had young Asian women read articles about their identity, either as female, or as Asian, and then take a math quiz.  When they read about Asian identity, they scored super-high, when they read about female identity, they scored low.

This is a common topic of discussion around my lab, since there are many female graduate students and professors in biology, and we hear all the time of measures to get girls interested in science, increase career advancement and other efforts to make working better for female scientists.  The overall goal is to increase the number of women in science.  However, I’m a little concerned that people don’t pause and ask what’s really going on, or ask why it’s happening.  For example, the lead of the NPR Article on the recent psychological study poses this problem:

Over the years, educators, recruiters and government authorities have bemoaned the gender gap and warned that it can have dire consequences for American competitiveness and continued technological dominance.

Really?  That’s the problem?  We’re not keeping up with Finland?  The reason we need to keep more women in scientific professorships is so that the Japanese won’t be smarter than us?  Not only does that sound kinda hostile to everyone who isn’t American (which is quite a few people), but it paints a nice, simplistic picture over the real problem.

Perhaps the real problem is exactly what the quotation points out: our ridiculously competitive society.  Maybe more women than men figure out earlier on that the goal of their lives shouldn’t be helping America crush Iceland.  A big problem in science is that most scientists believe that the number one goal in life is to be factually correct about everything.  Perhaps more women than men figure out that there are other things that are more important: things like compassion, kindness and generosity.  Is anyone doing research on that gender disparity?  Is anyone running a program to recruit men into kindness rather than insane competitiveness?  No one has tried to recruit me.


The Leaking Pipeline: Should I Go to Graduate School?

October 28, 2010 1 comment

A recent USAToday article showed the results of an analysis of 2010 census data, showing that more women are going to college for what are traditionally thought of as male-dominated fields. I think this is good news. I believe our public lives should mirror representation in our households to some degree, and I think that there are plenty of women out there who will make great scientists. My advisor is a woman, and she’s bloody brilliant. Many of the professors I work with are women, and they are all capable people that I certainly would never think less of for their sex. Having always been in a field that’s been receptive to women (i.e. not physics), I’ve never thought that female colleagues would be absent from my scientific career. I’m glad to see people reporting these changes in the news. However, the article, and most that I’ve read over the years, completely misses the point of the real crisis in academia with regard to gender: the leaking pipeline.

As long as I’ve been in academics (most of my life), people have known that the real problem with representation of women in science is the shortage of female professors. Female graduate students are, in many fields, equally represented with male graduate students, and requisition of a Ph.D. does not seem to correlate with gender. However, there are far fewer female professors than male professors in most scientific fields. Where are all these female Ph.D.’s going?

The Leading Hypotheses

Quite a few people have been burned at the stake for discussing this topic, but I still feel compelled to discuss it because I think it gets at another problem that I’ve never heard anyone discuss. There are good reasons why no one’s discussed it, and I’ll cover that a little later. For now let’s consider the leading hypotheses of why women seem to exit academia after receiving their Ph.D.s (remember, that’s not my opinion, it’s a well-established fact).

Women are bad at math

This is the idiotic idea that got Larry Summers ousted from Harvard. We should note, in his defense, that he didn’t actually suggest that women were bad at math, he just mentioned how no one has seriously considered the idea. Nevertheless, this idea is preposterous on quite a few grounds. Just using my own career as an example, the women I’ve known in my field have been, on the whole, much more quantitatively oriented than the men I’ve known. The guys have all known the requisite amount of statistics to get by, but I’ve known far more mathematically-oriented, or statistically-oriented female biologists than I’ve known such men. Besides my own experience there’s the fact that mathematics (pure math, that is) is one of the only fields outside of biology where there have been quite a few notable women: Emmy Noether, Sophie Germain, and Grace Hooper — if I can steal her from engineering — are but a few.

Even if something about being a woman, something cultural, biological or otherwise, prevented women from excelling due to problems with math, that wouldn’t prevent them from making huge headway in any of the biological sciences, psychology, or even engineering. On a logical basis, this idea doesn’t explain the disparity between females exiting graduate school and entering academic careers. Women wouldn’t be gaining Ph.D.s at the same rate as male counterparts if they were bad at math. We would not see a leaking pipeline, we’d see a closed pipeline.

Women tend to choose different professions

Even this seemingly innocuous suggestion that women are different (even in a good way) from men, makes most American women I’ve known turn bright red and foam at the mouth. What I mean about this being good is that I am probably not nice enough to be a public school teacher, but if a woman feels like she could be good at that, better that she go into that than me. Anecdotally, I know many women who have gone into mental health, teaching, medicine, social justice work, advocacy, and other non-scientific, somewhat humanitarian lines of work. I’d say all the professional women I know who aren’t doing something like one of these fields, is in biology, and that’s because I hang out with biologists all the time.

However, how can this explain the leaking pipeline? Are women going into graduate school in science and engineering, gaining advanced degrees and then becoming social workers? That doesn’t make sense either. Especially because for all those fields, you would need special training that is specific to those fields. All of them are just as valuable or more to society than science. We need mental health professionals, probably more than we need scientists right now. India needs scientists, Americans are sick; we need people to fix that. So “good for you” if you are choosing a different profession, but that doesn’t explain the leaking pipeline.

Who cares: why would they want to be scientists?

This is not so much a hypothesis as advice you should consider. The academy is a huge macho pissing match. A lot of my interactions in science have basically been on the level of “I have more publications than that guy! How dare he reject my paper!” I used the male pronoun on purpose there. Why would you want to be a part of that? I don’t want to be a part of it pretty often! Even if you love science, there are a lot of ways you can make a difference outside of academic science and be respected and paid. If you’re into biology, you could get a master’s degree and work in wildlife biology, either with government or with the Nature Conservancy and you would make a living, and see the fruits of your labor, and you would only have to take part in this pissing match if you wanted to.

Could this explain the leaking pipeline? A (coincidentally female) colleague of mine remarked that many graduate students get into the “Concorde fallacy”: by the third or fourth year of graduate school, if a student has changed his or her mind about being in academic science, then he or she would be in a situation of having already spent a huge amount of time and emotional energy into getting that octagonal hat. By then he or she might feel like “I better get my Ph.D. or all of this will be wasted time.” I knew one person who (luckily) changed her mind after only a year-and-a-half and left with a master’s degree. Lucky her; she wouldn’t have made that decision so easily (and I’m sure it was not easy) if she had been in her fourth year.

This factor might explain a lot of choices that lead to the leaking pipeline. I’ve heard from plenty of people whose sister, daughter or friend made this choice. I even heard from one first hand: I was out birding with a couple of women who had both described themselves to me as housewives. Their kids were already in college, so I tried to learn more about them. The one in the passenger seat had a Ph.D. in biochemistry from Stanford.

The question is then: why have I never heard of the person in question being male? I have met one stay-at-home dad who has a Ph.D. in physics, and he’s the only one ever. Why is the subject of that story almost always a woman? My favorite reasons for this are societal, and you can find plenty of hypotheses from your favorite feminist writer. I feel obliged as a man to mention that it’s pretty rough being the only dad at the playground with the kids — take a day off of work, and take your toddlers to the park just to experience this — it’s weird! How do you think I met that guy with a Ph.D. in physics? Beyond that, as much as women are expected to choose leaving work to take care of kids, men are often discouraged from doing so in very covert, but highly coercive ways. All it takes is a stern look from the HR manager and a societally-conditioned man starts thinking “Oh crap, how am I going to support my wife and kids? Sh*t!” I’d like to see the statistics on paychecks of men who choose to work part time, or take time off to take care of their kids. My gut tells me the comparison would reveal the familiar $0.78 often quoted when comparing women’s paychecks to men’s.

They shouldn’t go in the first place

The last hypothesis, that I will discuss at great length, is that men and women go to graduate school for the wrong reasons. I have never heard anyone discuss this possibility (I’ll discuss why in a minute). But why would women disproportionately go for the wrong reasons? There are two reasons: one is a demographic effect. Women exit the academy as their priorities change. Most people go to graduate school between the ages of 25 and 35, right when the ol’ clock ticks in. Add in the societal conditioning mentioned above and you have more women leaving than men.

People go to graduate school for the wrong reasons

Make no mistake: I’m not saying that women shouldn’t go to graduate school. I’m saying that most people who go to graduate school — men and women — shouldn’t go in the first place. There are plenty of reasons not to go, but chief among them would be that you know going in that you don’t want a career in academic science. “Who would go to graduate school that doesn’t want a career in academic science?” you’re saying. Someone who doesn’t understand what a Ph.D. is for. Someone, for instance, who thinks that a Ph.D. is just a level of education that someone can attain because they want to be very well educated. I have met these people.

I spoke to one woman who said that she just wanted to be really smart, and the best way she knew to accomplish that was to get a Ph.D. She chose a topic and pursued a Ph.D. and now works part-time as an environmental activist. This is intellectually on par with a friend-of-a-friend who decided he should be an expert in Gilligan’s Island because he was surrounded by intellectuals and felt outclassed. Have you thought of reading a book?

A woman I knew when I was in medical research wanted to get a Ph.D. in psychology because she wanted to be a “very-well educated stay-at-home mom.” Consider that she said this in an office where she was surrounded by other women who were fighting tooth-and-nail to get into graduate school because they wanted to be successful clinical psychology researchers. These other women needed Ph.D.s to get started doing what they wanted with their lives, and this woman thought it would look nice on her wall.

The only conclusion I can draw is how insensitive and irresponsible that is. If you know going in that you’re only going to be competing with people who actually need something a heck of a lot more than you do, kindly step aside. Otherwise you’re providing unneeded competition. Especially if you have really good grades, and you know that getting in will be easy for you. Don’t unnecessarily out-compete people who deserve to go to graduate school. As well as figuring out what your career goals are, you have a responsibility to consider whether you should go to graduate school.

Another reason that you shouldn’t go to graduate school is that you will be exploited. Some of us (theoreticians like me) are totally useless for anything but teaching; if you do benchwork, however, you are cheap labor. Consider that and then consider if it’s worth it. Unless you’re at the Nobel Prize level, and this is true of many people who still are, it makes the most sense to have graduate students and paid techs in the lab while you deal with administrative and service obligations. Professors have to do a lot: I’m not denigrating “publish or perish” but I’m saying you shouldn’t expect to see professors actively gathering a lot of their data. Their level of success is built on interacting with their departments, colleagues, scientific societies, or getting into industry. If you think grad school is supposed to be “the time of your life” (and I’ve met more than one such deranged person) think again.

As a parent I definitely know that another reason you might not want to go to graduate school is that your priorities may radically changed when you start a family. Marriage is enough to change a lot of people’s minds about how they spend their time. Kids are an unstoppable force. Having your own kids goes way beyond “Look at the baby!” When you have kids — and this is a good thing — you realize that you don’t need a Ph.D. to be respected, successful and have a fulfilling life. If your paper gets rejected, your kids will still love you. If you leave with a Master’s degree, your kids will still think you’re a really cool scientist. If you go to work at a software company, or take up a customer support job in the pharmaceutical industry, your kids will still be proud of you. Kids can convince the most stalwart, dedicated scientists that the academy is a waste of time without saying anything out loud.

Good for families, bad for the academy. Again, not having enough women in faculty positions is wrong. However, if you are searching for causes, you need to look beyond the “power structure” of white males constantly coercing females into leaving, and paying them less when they stay. There are plenty of reasons for the leaking pipeline that are not amenable to Marxist analysis.

If you’re a man or a woman you need to think about all the factors that go into scientific training. You also need to enter graduate school with the right priorities. Don’t go if you just want to be really smart. That’s not fair to people who need a Ph.D. to make a living. Don’t think it’s going to be fun, and don’t make “fun” your primary motivation: graduate school is not an extension of college. Don’t go right after college: being older and more mature (in particular over 26) is a huge asset that most people underestimate. When you’re older you’ve not only spent more time learning your field, but you’ve spent more time learning how to be a successful person. You will know how to handle conflict, how not to let people push you around. And you will know when science should not be your highest priority. Just on the basis of data, by that age you will probably have the right mate to help you survive graduate school. Plenty of people I know have entered grad school under 26, but I’m sure as hell glad I waited.

Most of all don’t go if your parents have bullied you into it. You have to consider your whole life, and how it will affect your other plans. Talk to as many current and former students as you can; make sure you get a variety of perspectives. If you are only hearing that grad school is going to be fun, you’re not talking to enough people. You need to hear some horror stories; I’ve left quite a few out from this essay.

IBM program shows ‘cash for chunkers’ pays dividends

October 4, 2010 Leave a comment

An article in USAToday shows that IBM employees who participated in a program to improve health-related habits showed definite improvement when the company offered money as a reward. I know what you’re thinking: duh. IBM actually doing this and releasing the results is fantastic because it shows that people can make improvements. I’ve long been saying that medical professionals and public health workers should start appealing to people’s vulgar motivations: for example, breast-feeding proponents should be promoting breast-feeding as a weight loss method, not a cancer prophylactic. However, just giving people money is an even better idea.

Creation came ‘from nothing,’ not God: Stephen Hawking –

Creation came ‘from nothing,’ not God: Stephen Hawking –

The Grand Design, which the publishers call Hawking’s first major work in nearly a decade, challenges Isaac Newton‘s theory God must have been involved in creation because our solar system couldn’t have come out of chaos simply through nature.

I hope no one thinks this is anything new. This wasn’t even Newton’s idea and was first challenged by David Hume less than a century after Newton died. Give me a break: are Richard Dawkins and Stephen Hawking going to go around proving the non-existence of God to everyone, like the immortal character in Life, The Universe, and Everything, whose goal is to insult every living being in the galaxy?
