A more inclusive admissions process Isn't this basically saying "we're admitting more, less qualified females and fewer more qualified (relatively) males". I see this all the time in STEM related admissions and I'm not sure I like it. I'm for encouraging women in STEM and I love that lab culture is much more open and welcoming of women nowadays (of the programs I work with, many of them have >60% women) but there does come a point where we've built a whole new level of institutional discrimination. I know of many well qualified male applicants that were denied to make room for substantially less qualified female applicants all in the name of "equality". It's not equality if you're elevating one gender to artificially make things "equal" on paper.

See what I just posted, 29% of the class of 2004 women failed to graduate in the major within 4 years. Continuing my thoughts on the effect of the dot com crash, if the attrition was mostly transfers we'll likely never know the reason(s), especially since the one your positing is impossibly un-PC. Worse, if you're right, recent women graduates of the program could have the affirmative action stigma. Or the failure rate could reflect a common disconnect between the admissions office and the faculty, except in this case it's all in the department, and a lot of the faculty didn't buy into the program to the extent of lowering standards "too much".

  CMU's overall 4-year graduation rate is only 71% so that sounds like women in the CS program graduated at the same rate as men: http://collegeapps.about.com/od/collegeprofiles/p/Carnegie_Mellon.htm http://collegeapps.about.com/od/collegeprofiles/p/Carnegie_M.... CMU, like most engineering schools, has high levels of major attrition: http://hlt.media.mit.edu/dfe_readings/fisher_2002_clubhouse.pdf http://hlt.media.mit.edu/dfe_readings/fisher_2002_clubhouse.... (see Figure 2).

    We can't say that which such limited data. E.g. it could be the whole school lowered its admissions requirements without sufficiently lowering the real graduation requirements, due to pesky faculty, departments determined to maintain their reputation and/or not lose accreditation, etc.
    - rayiner 13y ago
      My point is that simply posting the 4-year graduation rate of women in the department in isolation is misleading. At my undergraduate school (Georgia Tech), only 31% of people graduated within four years (70% by five, 80% by eight). Big attrition rates are normal for focused engineering schools.
      - hga 13y ago
        I do not believe they're normal for the top schools. Absolutely not for MIT, and as one of the top 4 (with no real second places) CS schools I'd hope CMU's CS department is the same. But we do need more information. E.g. if you think you want to major in EECS at MIT you'll likely take your first course before you declare your major at the end of your freshman year, and if it's really not for you you have a good chance to realize it. Prior to the new post-dot com crash panic curriculum this has been complicated by the department's opinion that you can't separate EE and CS and what that entails, but still, no one will think twice of your transferring in your sophomore year. But at CMU you apply to the department for that major, for one of 135 seats, so we'd be astounded if there wasn't this sort of attrition, and to judge this experiment we'd need to know if it changed significantly. Still, my general point remains, the author is totally failing to realize, let alone think about the attrition rate.
        junelin 13y ago
        Yes there was a lot of attrition from the initial experiment when they started with 42% because they let too many women in who didn't know what they were getting into and then decided that CS wasn't for them. The easiest intro to computer science class was essentially all women, and I think many of them dropped out. But the fact that 30% of the graduating class in 2004 was women vs <7% in 2000 is still pretty impressive.
  - eevee 13y ago
    That doesn't explain the gap, though: the same class went from 42% women starting in 2000 to 30% women graduating in 2004. If 71% of both men and women graduated, there should still have been 42% women at the end.

You're presupposing that whatever admissions standard existed before was "neutral" and any deviation from that involves discrimination. But consider the specific changes made: "In the past, admissions gave preference to people with lots of previous programming experience. The new criteria focused on potential by targeting students who showed science and math aptitude as well as non-academic strengths like leadership. The department made it explicit that no prior experience was required." None of these measures seem to me to discriminate against men. Also, the enrollment gender ratio of 40-60 isn't that far off from the representation of women and men among high school students who score 750 on the SAT Math (CMU's interquartiles for SAT Math are 690-790), which is roughly 35-65. MIT's experience evening out its gender ratio is illustrative. Unfortunately I can't find the link right now, but MIT found sometime in the 1990's that women were outperforming their admission predictors, based heavily on SAT scores, relative to men. So they rebalanced their admissions process to put less emphasis on SAT scores and more emphasis on high school GPAs. Also, "equality" here is a more complex issue than you're making it out to be. Social conventions are self-perpetuating. You can't just remove the overt discrimination and assume things will shift back to a healthy equilibrium. Once you have bent a metal beam outside the elastic region you can't just remove the external force and wait for it to straighten itself out! Illustrative here is the legal industry's experience with fairly aggressive affirmative action for women in the 1970's and 1980's. Law firms went from being 95% men to being almost even, and that new equilibrium was self-perpetuating. The ratio stayed roughly equal even after the measures were phased out.
- hga 13y ago
  However MIT didn't achieve its current ratio without significantly watering down the core requirements everyone has to pass. This started before the '80s, and it didn't ruin the Institute's reputation, but it had some clear effects. On the other hand, there is only one MIT, and the intense self-selection that occurs before anyone applies has allowed it to get away with all sorts of stupid admissions tricks going back many decades. E.g. for a long time it didn't have a professional running the office.

I don't think that is what it means. They aren't letting in 'less qualified' women. What they are doing is realizing that their previous admission process was not doing a very good job of selecting the best possible candidates. They were choosing people who had previous programming experience; there are a lot of people who would do very well in programming but just haven't been exposed to it yet. It turns out, a lot of those people who would do well but haven't been exposed yet are women. Imagine you are trying to select people to join your music school as clarinet students, and you have two candidates. One is slightly better on the clarinet than the other, but the currently better student has played for years while the other has barely started. The one who barely started has much more room to grow, and in many ways it would make sense to pick them for your school. If you only select the people that already have training in the field your school is teaching, you aren't going to get the best bang for your buck.
auctiontheory 13y ago
Isn't this basically saying "we're admitting more, less qualified females and fewer more qualified (relatively) males". I used to think exactly like you when I was much younger. And I thought I was one of those "more qualified" guys. Now I observe that if MIT's goal is to admit students who will use technology to make a positive contribution in society, filling the class with men who are "smart" in exactly one dimension ... is not the best way to achieve that goal. To put it another way, if you want to maximize future impact, trading in 100 Math SAT points for 100 EQ points is an excellent deal. And don't even start on "equality." If you're even thinking about MIT, you've had a hugely unequal leg up in the global birth sweepstakes.

> Isn't this basically saying "we're admitting more, less qualified females and fewer more qualified (relatively) males" Not necessarily. What they mean by "more inclusive process" is: In the past, admissions gave preference to people with lots of previous programming experience. The new criteria focused on potential by targeting students who showed science and math aptitude as well as non-academic strengths like leadership. The department made it explicit that no prior experience was required. It sounds to me more like they fixed a flaw in their prior process. Remember, we are talking about Carnegie Mellon, one of the best computer science schools in the world, not some random trade school. As Dijkstra correctly quipped: Computer science is as much about computers as astronomy is about telescopes Yes, programming experience can be useful in some areas of computer science, and even if your interests lie in those parts of CS that do not involve programming at all your undergraduate degree will surely require some courses in those areas where it is useful, and so knowing some programming is useful to all computer scientists at some point. However, as HN often points out (often as part of telling someone they don't need to go to college), you can become a good programmer and developer on your own with no formal instruction. The same applies to people in college--anyone with the aptitude to get into Carnegie Mellon should be able to easily pick up any programming they need in CS on the side. Having programming experience be a significant factor for admission to a computer science program makes about as much sense as having welding experience be a significant factor for admission to a mechanical engineering program, or mental arithmetic proficiency for admission to a math program.
- cschmidt 13y ago
  Good point. I was admitted to the University of Michigan in engineering, where I majored in chemical engineering, despite having never done any chemical engineering in my life. That applies to most engineering. How many students in mechanical, aerospace, etc. had done any of it in high school? Why would CS be different? (Now, of course, I program extensively. I picked that up on my own.)
abalone 13y ago
You either didn't read past that subheading or are just trolling. They clearly state that by "inclusive" they mean they more purely select for "science and math aptitude" and "strengths like leadership." Whereas previously they were also factoring in prior programming experience (at the high school level). Prior experience is going to reflect gender discrimination and peer pressures that girls experience in their teens. They are more precisely selecting for high-aptitude candidates with strong potential. A very rough analogy would be selecting candidates for a kid's golf school. If you include "prior golfing experience", you're going to bias towards the rich white kids while excluding a ton of very qualified kids with great athletic potential. By excluding prior experience, you're more purely selecting the best qualified candidates for a golf school. You might have a point if the goal was to start coding (golfing) immediately on day one, like in a professional job. But it's a school. They should select for future potential.

All we (men) can ask for is equality in programs dominated by females. What this university did to increase proportion of men in Gender Studies?
lliamander 13y ago
I prefer to avoid uncharitable interpretations, so I am hesitant to jump to such a conclusion. However, I will admit that judging admission based upon "non-academic strengths like leadership" allows personal biases and political forces to seep into the admissions process. Are admissions counselors, or computer science professors, really qualified to judge qualities like "leadership"? The potential for the kind of political corruption that you inferred does make me concerned. Now, I have read Dr. Harper's explanation of the change to the CS coursework, particularly with regard to the introductory classes. Apparently, when you introduce students to programming as an extension of algebra (i.e. functional programming) then you build upon timeless mathematical intuitions and reasoning abilities as opposed to mastery of the ephemeral and accidental complexities of C, Java, or Python. Not only does this seem to lead to a greater proportion of women participating in computer science, it leads to a greater overall retention. You can read more about it here (https://existentialtype.wordpress.com/2012/08/17/intro-curriculum-update/ https://existentialtype.wordpress.com/2012/08/17/intro-curri...).
- hga 13y ago
  WOW. I'm really impressed. And that's totally, 100% entirely different that MIT's approach to things. In, of course, directions I approve of. Then again this is the work of a CS department with roots in math, business, and e.g. AI, and MIT's roots are in its pioneering EE department, it's resolutely EECS, and the last time I checked, the vast majority of undergraduates get EECS degrees, vs. ones that are mostly one or the other.
  - lliamander 13y ago
    You might also be interested in the work of Dr. Mark Guzdial on the subject of introducing students to programming/computing (https://www.youtube.com/watch?v=wIkRUW6BEBc&list=WLF05B05A865F5765A https://www.youtube.com/watch?v=wIkRUW6BEBc&list=WLF05B05A86...). Now, he argues that language doesn't matter, and that what's important is teaching concepts through engaging applications (more akin to the MIT approach, from what I can tell). Clearly, that approach has had pretty good success (perhaps more so that CM, it's hard to know). However, it does not strike me that these two approaches should of necessity be in conflict. Why can't we use a good functional programming language (like Scheme, ML, or Haskell) to teach useful concepts through interesting applications while still leveraging those mathematical intuitions? I think we can. The idea of using a language with a functional core (e.g. Haskell, Clojure, Erlang, OCaml) has been gaining traction in the industry.
mathattack 13y ago
As they worded it, I don't think so. They included potential and leadership, in addition to experience. There's a judgment call on if that's less qualified or more. If they said, "We'll weight GPA and test scores less for women" then it's lowering standards. They also don't say if the class size is growing or shrinking. At most schools it's growing dramatically, and probably was the case in the 90s when the study was done. It probably was not the case in the dot-com bust. My impression is that CMU, MIT and other top schools can increase the gender balance without sacrificing quality. The national challenge is can everyone else?
