Somehow the idea that this is all caused by people applying to more places doesn't cut it to me. It might account for some of it, but not all of it. A lot of this is probably fairly chaotic and complex. For example, the GI bill probably contributed directly somewhat also, but also probably led to cultural shifts because of the veteran population, which then in turn changed career and educational expectations, but the GI bill itself reflects WWII, which also reflects cataclysmic societal changes (that is, WWII caused many significant things, but was also caused by many significant things).
Speaking as someone who has done research on selection and standard testing, and whose first-hand experiences support what I see from the theory and research, this is kind of horrifying, because it inevitably leads to increases in bullshit.
The accuracy of any of the selection methods we use in education is very poor. It just is. Standardized tests, "holistic review", all of it. It's not useless, but it is poor. It's the sort of thing that works well for a certain level of selectivity, but not past it. Once you go past it, you're selecting on well-impressioned noise, and incentivizing bullshit.
Somehow this all seems related in my mind to the rise of concerns about replicability in science, college admissions scams, and the age of fraud in general (https://www.theatlantic.com/entertainment/archive/2019/04/the-mueller-report-theranos-billions-american-scams/586297/ https://www.theatlantic.com/entertainment/archive/2019/04/th...). Something is broken. Probably many things.
- CompelTechnic 7y agoThe SAT reliably correlates with IQ, and of any psychometric variable we are able to measure, IQ has the strongest correlation with long-term socioeconomic success. Insofar as it is useful to funnel smart people into college, using the SAT is a good way to filter them.
- mj_olnir 7y agoDo you have a source on the first claim? I'm curious, as someone who was slightly involved with a documentary [1] exposing pitfalls of standardized testing. Generally the SAT only has shown a weak correlation between test scores and first year (some studies I read showed only first semester, but I don't have them on hand right now) collegiate performance [2].

- jasode 7y ago>Generally the SAT only has shown a weak correlation between test scores and first year [...] collegiate performance [2]. That's not what your cite says. The InsideHigherEd article actually shows a strong correlation between SAT and grades but Aquinas identified a minority % of schools where it didn't. Please carefully read the 3 bullet points again and notice the minority percentages. Your qualifier of "Generally" in your comment is misrepresenting Aguinis' findings.

- kestreloats 7y agoWhy Taleb? I hate that piece because most of what he's referring to has been dealt with for decades. It's like "narcissist who knows nothing about a field doesn't bother to learn anything about it and as a result takes down a strawman to make himself look good."
- asddasd 7y agoTaleb should stay in his lane. He sounds like a "get off my lawn" old douche when he talks about anything other than financial markets. His central tenet in that article is that IQ doesn't correlate with wealth and is therefore useless. How enlightening.
- physics137 7y agoWhy not just administer an IQ test then?
- erentz 7y agoSAT presumably tests you have learned certain things in high school and so are ready for university. E.g. you won’t show up to your first university math class needing to learn all of high school math, and thus be unable to complete the class.
- lmkg 7y agoThere is a Supreme Court ruling that IQ tests are assumed to unfairly disadvantage minority candidates. This was in the context of employment rather than college admissions, but I don't think anyone has been bold enough to test whether it applies. Broadly speaking, IQ tests tend to include a lot of cultural assumptions and therefore members of the in-group will test higher than members of out-groups of the same aptitude. IQ tests are therefore treated as discriminatory (disproportionate impact) "by default." The administration of a particular test for a specific purpose can usually be OK'd by either showing that particular test is not discriminatory, or by showing that particular test has a measurable correlation to the specific purpose for which it's used. My understanding is that "specific purpose" in the employment context means the individual job description, not just hiring in general.
- cbm-vic-20 7y ago> There is a Supreme Court ruling that IQ tests are assumed to unfairly disadvantage minority candidates I wonder if there's an "IQ test" that unfairly disadvantages non-minority candidates. It would be interesting to see the results if the same pool of people (minority and non-minority) take both tests.
- kestreloats 7y agoSo I agree with you about SAT <-> IQ, and IQ <-> SES. However... IQ isn't the only correlate of success. I think if you look at it all, there's a large dose of conscientiousness (which standardized testing companies are now going after), and attractiveness/charisma... ... but that's on the individual side of things. There's also a whole host of societal and random stuff that is outside the control of the individual, or maybe is significant to a person, but that studies tend to treat as irrelevant. Also, saying that the SAT is useful as a selection device doesn't mean it's the only useful selection device, or that as a selection device it's very good. Offhand I don't remember the numbers, but standardized test score probably correlates .45 or so with first-year college grades? Think about that for a second. First, that's a ton of noise. That's not very predictive at all. Second, that's first-year college grades. Change the criterion but it's still the same: your best tool really is a pretty fuzzy predictor. So now take this very fuzzy predictor, add some other fuzzy predictors that at best get things up to like maybe .6 correlation? Still fuzzy. Now you're going to be really selective on these things? What you're going to end up with is a lot of people who would have done as well but for whom the stars didn't align right at a particular period in their life. But now we as a society have this crazy income inequality, rent-seeking monopolies of all forms, and a general winner-takes all climate, so these small meaningless differences get amplified tenfold. The conversations about this too have this kind of all-or-nothing quality, like you're forced to choose between "standardized tests are meaningless" or "standardized tests are valid predictors for a large portion of people so we need to treat them as infallible predictors for everyone." The truth is really much greyer than these positions: yes they predict, but they predict pretty weakly, all things considered, and generally for people who fit into a certain box. This all might be fine, except now we've structured our society in part around these oversimplified assumptions, pretending it works when it doesn't really. It might be ok when there's lots of second chances, lots of opportunities for people to get back on their feet from the vagaries of life, and good opportunities in general for everyone, but when resources gets hoarded by fewer and fewer, there's more noise, that's compounded by people gaming the system, etc. etc. etc. Just as a thought exercise: what do most human traits look like in terms of distribution? They're pretty normal, pretty Gaussian. What does income look like? Not that, not at all. The discrepancy between them should be shocking to everyone.

- paulpauper 7y agoIQ and the old SAT are highly correlated, and is why Mensa uses the SAT for admissions purposes
- terryschiavo22 7y agoIQ is a lot like GDP. It doesn't measure what we need as accurately as we need. If you keep that in mind, though, it can remain a broadly useful metric.
- threatofrain 7y agoIf we predominantly cared about intelligence then shouldn’t we not beat around the bush and directly test for it?
- ordinaryperson 7y ago> The accuracy of any of the selection methods we use in education is very poor. It just is. The SAT when combined with the high school GPA (HSGPA) has an adjusted correlation correlation coefficient of 0.56 with first-year GPA, meaning the combined measurement accurately predicts how a potential college applicant will perform in their first year of college 56% of the time. [1] That's actually pretty good, what other proposed metrics can say their signals match outcomes with 56% validity? How much you liked their essay? Lower SAT scores have about 63% retention rate for first-year students whereas high SAT scores have about a 95% retention rate [2]. That is, high schoolers with poor SATs drop out of college about 40% of the time in their first year. Standardized tests have many problems -- obviously -- but no one has developed a less unfair system. When colleges abandon standardized tests what else are they relying on? Random signals made up by admissions officers? That's worse than job interviewing. I have no problem criticizing standardized testing, but I feel everyone who does should be obligated to propose a better alternative method with a higher validity rate than 56%.

- geebee 7y agoThis is a pretty good write-up: https://blog.udemy.com/correlation-coefficient-interpretation/ https://blog.udemy.com/correlation-coefficient-interpretatio...
- donaldknuth123 7y agoThis validates your parent comments statement. Was that your point? The OP is not interpreting correlation correctly.
- germinalphrase 7y agoThe difficult solution is increasing the accuracy and “trustability” of k12 assessments. As is, high school educators are not assessing their student in a manner that allows for real judgements of their students’ knowledge/capabilities/creativity/etc. by an outside party. We spend immense amounts of money, time, and effort creating and assessing students in school, but the results are only useful with the context of progressing within those specific courses. Trustable assessments would go a long way to accurately rewarding merit.
- threatofrain 7y agoCurrently standardized testing better predicts future academic performance than years of GPA, which in a way is the sum of teachers’ views on a student. But teachers still prefer teachers over standard tests, and they shun conversation with their researching peers. The classroom is their kingdom and that’s how people prefer it.
- germinalphrase 7y ago“Teacher tests” often have different objectives than solely measuring one student’s ability compared to another. Likewise, the investments made in the creation of standardized tests are not likely to be matched by classroom teachers due to logistical constraints even if they have the necessary knowledge to create an equally valid assessment. The objective should be the creation of a system that allows teachers to retain the flexibility to modify curriculum in a manner appropriate to their specific student population while also maintaining the trust and reliability benefits found in standardized tests.
- spdionis 7y agoMaybe it is our expectation for everything to be fair, straightforward and honest that is broken? These expectations are the root of the current outrage culture. It's as if now that we have these wonderful technological advances we assume every problem should have been solved by now, and get outraged when we realize we don't live in a utopia.
