CRIMSON: From what psychologists know, is there ample evidence to support the hypothesis that a difference in “innate ability” accounts for the under-representation of women on science faculties?
PINKER: First, let’s be clear what the hypothesis is—every one of Summers’ critics has misunderstood it. The hypothesis is, first, that the statistical distributions of men’s and women’s quantitative and spatial abilities are not identical—that the average for men may be a bit higher than the average for women, and that the variance for men might be a bit higher than the variance for women (both implying that there would be a slightly higher proportion of men at the high end of the scale). It does not mean that all men are better at quantitative abilities than all women! That’s why it would be immoral and illogical to discriminate against individual women even if it were shown that some of the statistical differences were innate.
Second, the hypothesis is that differences in abilities might be one out of several factors that explain differences in the statistical representation of men and women in various professions. It does not mean that it is the only factor. Still, if it is one factor, we cannot reflexively assume that different statistical representation of men and women in science and engineering is itself proof of discrimination. Incidentally, another sign that we are dealing with a taboo is that when it comes to this issue, ordinarily intelligent scientists suddenly lose their ability to think quantitatively and warp statistical hypotheses into crude dichotomies.
As far as the evidence is concerned, I’m not sure what “ample” means, but there is certainly enough evidence for the hypothesis to be taken seriously.
For example, quantitative and spatial skills vary within a gender according to levels of sex hormones. And in samples of gifted students who are given every conceivable encouragement to excel in science and math, far more men than women expressed an interest in pursuing science and math.
CRIMSON: Were President Summers’ remarks within the pale of legitimate academic discourse?
PINKER: Good grief, shouldn’t everything be within the pale of legitimate academic discourse, as long as it is presented with some degree of rigor? That’s the difference between a university and a madrassa.
Is Williams a college or a madrassa? Adam Falk, and (a majority of?) the faculty have decided that certain ideas may not be discussed on campus, that certain views are “hate speech.” Indeed, students who believe these things — or just want to hear those views from a published author who has spoken at places like the University of Pennsylvania and whose books are available in Sawyer Library — may very well be guilty of “hate speech” themselves, and therefore subject to discipline under the College’s Code of Conduct.
At the admissions end, it’s common knowledge that Harvard selects at most 10 percent (some say 5 percent) of its students on the basis of academic merit. … The rest are selected “holistically,” based also on participation in athletics, the arts, charity, activism, travel, and, we inferred (Not in front of the children!), race, donations, and legacy status (since anything can be hidden behind the holistic fig leaf).
This is not true. Summary: More than 80% of admissions at Harvard (and other elite schools like Williams) is determined by academic merit, measured by past success in high school (high grades in the most rigorous classes with the best teacher recommendations and top standardized test scores), all of which best predicts academic success in college.*
First, leave aside athletics for the moment; the preferences there are real and large.
Second, consider the raw data in terms of 25th and 75th percentile SAT scores. (I have taken the latest available data and simply added the Math and Critical Reading scores together.)
Harvard: 1390 -- 1590 Williams: 1330 -- 1540 Cornell: 1320 -- 1520
A difference of 50 or 60 points may seem small, but this is (back-of-the-envelope) 1/4 to 1/3 a standard deviation.** If we were talking about height, it would be as if the average student at Harvard were an inch or so taller than the average student at Williams or Cornell. There is no way, in a large population, to get this sort of difference unless the selection procedure has a major focus on SAT scores (or their correlates). In particular, there is no way that the top 25% (!) of the Harvard class has almost perfect SAT scores if only 10% (much less 5%!) is selected on the “basis of academic merit.” It is mathematically impossible.
Third, there are no meaningful preferences given for “the arts, charity, activism, travel” and other non-academic, non-sport reasons. Why?
- Harvard is not that different from Williams and, as Professor of Music David Kechley explained 11 (!) years ago, there is no meaningful preference given for musical talent.
- There is no need to give preference for things like music and art because academically strong students are often talented in music and art. Go meet some!
- There is no reason to give preference for music/arts because schools don’t compete with each other on that basis. Imagine that the quality of the arts and music was twice as good at Williams as at Harvard. Would anyone notice? No! No one goes to enough events at both Williams and Harvard to make that judgment. (This is one aspect by which athletics is different.)
- Even if you wanted to give preference to those students who would go on to be heavily involved in things like, say, student government and charitable work, there is no way for the admissions department to predict which students will do so, as Jen Doleac ’03 demonstrated in her thesis.
- Harvard does not have the time or money to meaningfully evaluate the artistic ability of applicants. With 14,000 applicants, the logistics are impossible. As books like The Gatekeepers and A is for Admission make clear, admissions officers make some notes about non-academic talents, but these attributes play a de minimus role in the process.
- “Travel?” Harvard prefers students who have done a grand tour of Europe? Give me a break! The biggest thing that teenage travel correlates with is family income, and Harvard gets plenty of rich kids already. Might Pinker be able to point to Harvard students who traveled a lot? Sure! But he could also find plenty of blond Harvard students. That fact doesn’t mean that the Admissions Office selects by hair color.
Now, every once in a while does something like music help? Sure! If the orchestra conductor calls up the admissions office and begs for some decent drummers, he may get helped out. But, overwhelming, even those drummers will have amazing academic credentials.
Fourth, even affirmative action does not change the basic story because black (and Hispanic) applicants are accepted under the same criteria as white/Asian students. The same process of looking at high school grades, course schedule, teacher comments and standardized test scores applies to everyone. Whatever it is that Harvard is looking for in white/Asian students, it is looking for the exact same thing in black/Hispanic students. Harvard just sets the bar lower for the latter. Being poor is probably an advantage. Being a non-US citizen is probably a disadvantage. But, whatever bucket you are competing in, the key criteria is academic success.
Fifth, legacy is a red herring. Do the math! There are 1,600 Harvard students in the class of 2018. There were around (I think) 1,600 Harvard students in each class in the 80’s. I can’t find good data on fecundity, but, judging from Williams, elite students from the 80’s go on to, at least, achieve replacement levels of fertility. So, there are 1,600 or so legacy students born in 1995/1996 who would love to come to Harvard (or at least be accepted by Harvard) for the class of 2018. But Harvard only enrolls about 200 of them!*** You think the other 1,400 go to Stanford? Ha! It is easy for Harvard, like Williams, to ensure that enrolled legacy students are academically equivalent to non-legacy students because the legacy pool is so strong. Turns out that Harvard parents tend to have academically talented children. Who knew?
Sixth, even in the case of athletics, academics matter because the admissions department insists. See here for some details. But, to the extent that Pinker has a point, he is correct that athletics plays an important part. And so does major wealth. But even if we combine the athletes and the donors, we are still talking about less than 20% of the class.
Big picture, Pinker’s description of Harvard admissions is fundamentally flawed because the vast majority of it (80%?) is, in fact, driven by “academic merit.” Unless you are a recruited varsity athlete or a billionaire’s child, you got in because your classes/grades/scores were better than the other applicants (at least within your race and/or socioeconomic class and/or nationality).
And this is easy to see if you follow the admissions process at your local high school, assuming it is the sort of school that sends lots of students to elite schools. On average, the high school students who get into Harvard have done better — higher grades in tougher classes with better teaching recommendations and standardized test scores — than the students who get into Williams, and then the same down the academic pecking order.
Steven Pinker is a voice of reason in many of the debates surrounding higher education. It is too bad that he is so misleading about Harvard admissions in this essay.
* Of course, it is not clear what scale Pinker is using for his 5% or what scale we should be using for our 80%. The main clarification that applies to the 80% is that, although the academic evaluation system is the same across categories of students, students are mostly competing against peers in their own racial, citizenship, and socio-economic bucket. If you are, say, rich and black, then Harvard admits use on the basis of academic merit in comparison with other rich/black applicants.
My preferred scale is to imagine that the Harvard admissions system is blinded to everything non-academic. All they see is your high school transcript and standardized test scores. Even in this scenario, more than 50% of the students in Harvard today would still have been accepted. Athletics and affirmative action do have a meaningful impact on admissions, but most of what is going on is still Pinker’s “academic merit.”
** Yes, I realize that this is a rough estimate. The standard deviation of individual SAT tests is around 100. I can’t find good estimates of the standard deviation of combined scores. If the scores from the two tests were uncorrelated, then the combined standard deviation would be around 141. But the positive correlation means that this is a lower bound. And, of course, we are talking about the far right tail of the distribution, where all sorts of weird stuff might happen. The larger point stands: it is impossible for Harvard’s combined SAT scores to be 50+ points higher than Williams/Cornell, year after year, without significant focus on SAT scores by the Admissions Department.
*** See our legacy admissions category for various calculations with regard to Williams. I doubt that things are much different at Harvard or any other elite school. Why would they be?
