Tests designed so that the Ivies pick preppies.

Leave a reply

Elite colleges strive to be selective, and they are, just not for the hard-working scholars they claim to select for. They claim to be color-blind, income-blind, and race-blind, aiming for the best: the most intelligent, most ethical, and hardest working scholar-candidates. Then, to their surprise and satisfaction, all the ivies find that the vast majority of the chosen come from the same rich families and prep-schools as 100 years ago. That happens because the selection is crooked with measures tilted to the rich, Protestant, and preppy.

Through most of the 1900s, most of the ivies had a Jewish quota, enforced formally or informally. They also did their best to discourage middle class, black, and Catholic students in the interest of maintaining the proper student mix. Under Woodrow Wilson, Princeton went further and admitted not one black student. When quotas became illegal, schools began to rely on athletics and tests, with blatant cheating as revealed by the “Varsity Blues” sting operation. In that sting, a dozen or more athletic coaches and high-school administrators were caught taking SAT tests for their richer, connected students, and/or making up phony athletic achievements. The Ivies claimed shock after the cheating was revealed, but it is beyond belief that no one had noticed that these top brains and athletes were neither.

Many top athletes are diagnosed as asthmatic. Some actually are. With the right doctor, you can get an advantage

Another version of this is that richer kids can get extra time to do SAT and ACT tests. The extra time doesn’t show up on the SAT or ACT score, you need a doctor to certify that you are dyslectic or have severe ADHD. Most boys are diagnosed with ADHD these days, itself something of a scam, but most boys don’t get extra test time. You need the right doctor and the right documentation, plus enough money and connections to get the test given by certified test-giver in your own private room. It used to be that the SAT and ACT would report the extra time, but this changed in 2004. Now the extra time, and the disease is not documented, just the higher score. There have been complaints, but the scam goes on. Similar to this, top Olympic athletes can be diagnosed with asthma, and allowed to use performance enhancing, anti-asthma steroids. Again complaints, but no change.

Ivy League schools also tilt to the right families by requiring signs of the right sort of leadership as evaluated by an interview and an essay (see my post on John Kennedy’s essay). You score high on leadership if you helped your relative run for governor. By contrast, if you organized a ping-pong or basketball tournament at your Catholic or Jewish school, you’re the wrong sort of leader. Eagle Scout is sort-of the right sort, and speaking against climate change on TV is. Greta Thernberg and Chelsea Clinton are climate leaders; you, probably are not.

The Ivys explicitly state that they choose for athleticism, but not all sports are equal. All the Ivies claim to need a good women’s lacrosse team, a good crew team, and some good high-divers. Are these sports unavailable at your high-school? What a shame, you’re not a real athlete. You can still try to get in based on extreme leadership and academics.

The Princeton alumni of 1993-1994 were primarily white, rich and preppy. Favoring their children helps insure that the class of 2024 is that way too.

There is no real reason that Harvard needs a top crew team, or needs to excel at women’s lacrosse or high-diving. Sport was not an admission criteria in the 1800s. It was added in the 1900s to avoid admitting Catholics, Jews, and Asians who tended to score well but could not compete on the selected sports. The president of Harvard, Abbot Lowell wrote, “Somehow or other the enrollment of the Jewish students must be limited”. The method he chose, and that all the Ivies came to use, included these tests of leadership and sport, plus a preference for legacies. The children and grand-children of alumni are given significant preferential selection at all the ivies. At Harvard, the acceptance rate for legacy students is about 33%, compared with an overall acceptance rate of under 6%. Since legacies are mostly white, rich, protestant, and preppy, the next generation is guaranteed to be the same.

The Ivies’ methods have been challenged many times over the years. Quotas were found to be illegal as early as 1964. Since then there have been claims of effective quotas, a cause that was pushed under the rug until Donal Trump took it up. Most recently, Harvard, Princeton, and UNC were sued by Asians. One of these, from a poor background scored at the top of his class with a 4.4 GPA and had near-perfect SAT scores, but was rejected for no obvious reason beyond race. The Supreme Court is expected to hear the case in 2023. Ahead of this decision, all eight Ivies have decided to dispense with testing for at least for now. The ivies claim that, by making tests optional, they will avoid locking out students who are great (though somewhat illiterate and innumerate). The real purpose seems to be to lock out pushy Asians who might sue them or be so bright they make the legacies feel dumb.

None of the above would matter if the Ivies were not so wonderful, at least the better ones are. I went to Princeton grad school, see photos. It was great despite its waspy leanings. If you can go there, or to Harvard, Yale, Cornell or Penn, go. My feeling for Brown and Columbia are rather the opposite: they’ve gone to the extreme and voted for BDS, see the text here for Brown’s version. Not only did they vote to boycott Israelis and Israeli produce, the “B” of BDS, the’ve also committed to suppress Zionists everywhere. That’s Jews who support Israel. Several, non ivy schools, have committed to the same. In their view, for open debate to flourish anywhere, proud Jews must be excluded. These are no longer colleges, but Klavens.

How to tell who is productive if work is done in groups

Leave a reply

It is a particular skill of management to hog the glory and cast the blame; if a project succeeds, executives will make it understood that the groups’ success was based on their leadership (and their ability to get everyone to work hard for low pay). If the project fails, a executive will cast blame typically on those who spotted the problem some months early. These are the people most likely to blame the executive, so the executive discredits them first.

This being the dynamic of executive oversight, it becomes difficult to look over the work of a group and tell who is doing good and who is coasting. If someone’s got to be fired in the middle of a project, or after, who do you fire? My first thought is that, following a failure, you fire the manager and the guy at the top who drew the top salary. That’s what winning sports teams do. It seems to promote “rebuilding” it’s a warning to those who follow. After the top people are gone, you might get an honest appraisal of what went wrong and what to do next.

A related problem, if you’re looking to hire is who to pick or promote from within. In the revolutionary army, they allowed the conscripts to pick some of their commanders, and promoted others based on success. This may not be entirely fair, as there are many causes to success and failure, but it seemed to work better than the British system, where you picked by birth or education. Here’s a lovely song about the value of university education in a modern major general.

A form of this feedback about who knows what he’d doing and who does not, is to look at who is listened to by colleagues. When someone speaks, do people who know listen. It’s a method I’ve used to try to guess who knew things in a field outside my own. Bull-shitters tend to be ignored when they speak. The major general above is never listened to.

In basketball or hockey, the equivalent method is to see who the other players pass to the most, and who steals the most from the other side. It does not take much watching to get a general sense, but statistics help. With statistics, one can set up a hierarchical system based on who listens to whom, or who passes to whom with a logistic equation as used for chess and dating sites. A lower-paid person at the center-top is a gem who you might consider promoting.

In terms of overall group management, it was the opinion of W Edwards Deming, the name-sake of the Deming prize for quality, that overall group success was typically caused by luck or by some non-human cause. Thus that any manager would be as good as any other. Deming had a lovely experiment to show why this is likely the case– see it here. If one company or team did better year after year, it was common that they were in the right territory, or at the right time. As an example, the person who succeeded selling big computers in New York in the 1960s was not necessarily a good salesman or manager. Anyone could have managed that success. To the extent that this is true, you should not fire people readily, but neither worry that your highest paid manager or salesman is irreplaceable.

Tale of a fast, accurate home COVID test

Leave a reply

My son works at a company called Homodeus. It’s part of 4Catalyzer, an umbrella of seven medical biotechnology companies with a staff of 300 scientists and engineers. One of the Homodeus products, still waiting FDA guidance is a COVID-19, RNA self-tester called Homodeus Detect. It tests for COVID RNA directly, not for antibodies, with tests are much faster than hospital tests, taking 45 minutes, but more complex than the unreliable test strips. So far, the Detect tests have shown no false positives or false negatives. That would suggest 100% reliable, except but there are a fair number of invalid tests. The invalid tests are lares due to the complexity, and also to the fact that you are testing snot, essentially. There is no blood-taking involved, unlike with the test strips, but  just a nasal swab, and the cost is moderate, about $35 per test. However you have to do some lab work. After you swab your nose, you put the swab in a heated liquid bath where chemicals break up the snot and dissolve the shells on any viruses or pollen present. After 30 minutes, you pass the liquid onto a detector strip that contains a conjugate protein that binds to SARS-CoV-2 RNA. Your answer appears 15 minutes later as one of three lines: one for positive, one for negative, or one indicating an invalid test. Invalid tests show up more often than they like, about half the time, especially when the test is done by amateurs. 

Getting an invalid test result is a downside of the current product, but I don’t think it should prevent sales. You get better at doing the test, and speed and lack of false positives and negatives is a bigger plus. It seems worthwhile to fast-track offer this test for doctors offices and hospital admissions, at least. I’d also like to see it used for airplane boarding and interstate travel, so that a person traveling might avoid the two week quarantine that many states impose. I’d certainly pay $200 or more to avoid a two-week quarantine, and if I have to do a second or third test, I’d do that too. 

At least some people realize it’s a big advantage to know if you are currently infections.

Because this test measures virus RNA, and not antibodies, it indicates infection virtually as soon as you’re infected. That’s a benefit for those wishing to fly, or to meet with people, an advantage that is not lost on Elon Musk at least (see tweet). The test also shows negative as soon as the virus is gone, and that’s big. In recent months the FDA has fast-track approved an antibody indicating test from Abbott Labs, but that test has many false readings and only indicates infection several days afterward, and it does not indicate when you are no longer infectious. 

The FDA has not offered to fast track this test, or any other like it for approval. They have not even indicated what sort of reporting and privacy requirements they want, so things sit in limbo, both for Homodeus, and for competing companies. Here is a story in USA today: https://www.usatoday.com/story/news/2020/07/29/fda-opens-door-rapid-home-covid-19-tests/5536528002. One big issue that the FDA is contact tracing. The FDA would like to be able to trace all the contacts of anyone who tests positive, while maintaining privacy as demanded by the 4th Amendment.

One way around the 4th amendment concerns would be to require anyone who uses the test to sign a waiver allowing the government to trace their contacts. Alternately there could be a block-chain enabled app that would come with the test. An app coms already providing a timer for when to move to the next step, and it includes a machine-vision system to help analyze dim lines on the indicator. Perhaps the FDA would accept block chain as a way to allow full reporting while maintaining privacy The FDA has yet to provide guidance on what they want, though. Without guidance or fast-track approval, things sit in limbo. Here is a scathing legal analysis from the Yale Law Journal.

You can get a free test, but have to do it at Homodeus headquarters in Guilford, Connecticut. It’s free, and results appears in about 45 minutes.. Homodeus has been manufacturing the test in quantity; if you are interested, use the following link to sign up: https://www.homodeusinc.com/research. Healthcare providers are particularly welcome.

The Homodeus detect test kit. Picture from this article in the New Haven Register.

Why did the FDA fast-track approve Abott’s antigen/ antibody test. Maybe because the tests rethought to not lead to lower mask use. Alternately, Abott has more political pull. You can read the FDA’s explanation here. In my biassed opinion the Homodeus product is good enough to fast track especially for hospitals and healthcare providers. It could save lives while allowing the economy to reopen.

What is learning?

3 Replies

It is common to spend the most of one’s youth in school — presumably learning something. The financial cost for primary education is a few hundred thousand dollars, borne by the state, plus 13 years or so of the student’s life. College learning costs another $50,000 to $200,000, borne by the student, plus another 4-6 years of life. The indication that you’ve learned something appears, in many majors by the ability to get a job that pays more than the school financial cost. But there is also a sense that you’ve learned something, and this is perhaps the only reward for students of film, religion, or archeology. My question is based mostly on this part: what is this learning. Is it the same as knowledge, a set of facts, or satisfaction — perhaps you could be as satisfied by ignorance or drugs. How do you evaluate the spiritual payback from 4-6 years of college? I don’t have all the answers, but ask to exercise my ignorance.

It would seem to me that an important standard of learning is that it should develop the mind and not corrupt it. But how do you recognize the difference? it seems to me one should leave with a set of mental skills should be new to you, recognizable to a normal outsider, and somewhat useful, as in the poem “Botany” even if you don’t use it. I’m not sure if the skills have to be true, by the way, or how useful they have to be. Perhaps developing a new confusion is better than having false notions — knowing that you doubt something.

sometimes education is the removal of false notions.

Sometimes learning can be the development of doubt.

If you’ve been educated in music, it seems to me you should be able to make sounds that appear pleasant to a normal listener; if you’ve been educated in mechanics, you should be able to make machines that work, and if you’ve been educated to think… perhaps then you should be able to walk into a discussion about something you once thought was true, and show that it is really false to an extent that others would accept it (and act upon it?). That is, my suspicion is that learning should involve an identifiable change –not only internal satisfaction, and I also suspect learning the new must involve unlearning the old.

Liberal Education may not be useful, or elevating

Education that isn’t useful isn’t particularly elevating

And that leads us to facts and methods: knowledge. Facts are good, they are the fuel and  substance of learning. Without facts there is nothing for the learning to attach to. But facts are often wrong — the ignorance of others, and even when right, they can be  deceptive. If you’ve learned the moon is made of rock, or out of green cheese, it’s pretty much the same unless there is a reason to think the fact you’ve learned is true, and unless you’ve a good understanding of what the fact ‘means.’ I can imagine a rock that is organic (a gall stone) and less solid than some (old) green cheese. The word rock or cheese must mean something to you to be a fact. Similarly in all subjects; if you learn that Shakespeare is a better writer than Poe, you should have a reason to believe it, and a clear understanding of the word ‘better’ in this context.

Turning to the knowledge of methods. It seems to me that learning a new method of thought, action, or argument is a necessary component of learning– one might even call it virtue, but this too seems to have limitations if it is not directed to use. A person is half-educated if he leaves school knowing how to do geometric proofs, but never doing any, or knowing how to run a great business, but never running one. A science graduate should at least be able to use the techniques learned to demonstrate that the world is made of atoms, and that the sun does not circle the earth and perhaps more. An argument can be made for traditional education areas of logic, rhetoric, mathematics, and dialectic. But these seem useless unless they are applied to a worthy end. One should do more with the new methods than to win drawing-room arguments.

There should be some satisfaction to accomplishments, but I'm not sure how it's learned.

Learning should provide satisfaction –in particular religious learning — but it’s nicer if it goes with doing good for someone (not only the poor) and the ability to earn an honest income. 

There should be a moral component of learning too, but here I feel less certain in describing it, or describing how it should be taught. Theodore Roosevelt said that “An uneducated man can steal from a rail car, “but an educated one can steal the whole railroad.” but perhaps stealing the railroad isn’t such a bad thing if it’s done legally. And as I don’t quite know when the honest stock deal is moral, I’m even more in the dark as to how to teach one to recognize the moral from the immoral in these situations. Two thoughts here: a student deserves some satisfaction from his or her learning and (from Aristotle’s Nicomachean Ethics) to be moral, the student has to earn an honest income. One who can not earn a living is bound to steal from someone sooner or later.

A final sign of learning, and perhaps it’s crown, is creativity, the ability to come to new understandings and develop new things. To do this productively requires some knowledge of the past plus an indescribable view of the future. A spark? A divine madness? Schools do not seem to be able to teach that, but it can help or hinder by either encouraging it, or beating it down. If you did not possess this ability when you entered school, you are unlikely to leave with it, even if you just did drugs, but school can teach one to direct the spark productively.

I’ve noticed that our high schools focus little on the above areas, perhaps because they are hard to test. Rather classes aim to the exams, and the exams test (as best I can tell), memorization, aptitude, and exposure. A surprisingly large fraction of our students leave diagnosed as ADHD. Still, strangely, our graduates do better than the Europeans.

Here is our latest hydrogen purifier to date being pressure tested. Output is 650 slpm; that’s 40 m3/hr, 3.5 kg/hr. The device is tied down for burst-pressure testing behind a blast fort, just in case the thing bursts during tests. So far, no failures, no leaks. I sure hope the customer pays.
