The purest distillation of the modern zeitgeist

Not much time, but I must memorialize this post by Kevin Drum:
Hillary Clinton describing her typical day in What Happened:
Six a.m.: I wake up, sometimes hitting the snooze button to steal a few more minutes. Snoozing leaves you more tired—there are studies on this—but in that moment, it seems like such a great idea.
Of course there are studies on this. And of course she knows about them. This is Hillary Clinton in a nutshell.
There's nothing wrong with paying attention to studies and following the tips.  But it just figures that that's how a member of the technocratic establishment would describe her mornings--in terms of studies and Best Practices.

Just try being human.  Climb down from Mount Olympus and be human.  Don't descend too far--you'll wind up being sub-human like Trump--but descend a few steps and see what humanity is like.

On a related note, Bladerunner 2049 was amazing.

A Eulogy For My Mother

I don't normally use this blog for such personal stuff, but I want a place to keep this, where it's easy to share.  So here's the eulogy that I gave for my mother, Ann Marie Sicilia Thompson, who passed away on September 13, 2017.

First and foremost, my mother was a mother.  She devoted all of her energy to it.  The stress and sleep loss are probably part of why she was so often sick.  She made sacrifices so that my brother and I could go to Catholic grade school.  She worked full-time, raised us by herself, and went back to college to finish her degree, because that's what was necessary.  She missed a lot of sleep for us.  In return, she expected the absolute best of us.  I knew that I could not come home with a bad grade or a report of getting in trouble at school.  It was simply not an option.

When my brother and I got older and moved away from home, it seemed like the highlight of her life was to fly out to visit us.  Whether it was flying to Europe when my brother studied in Spain or worked in Romania, or flying to California to visit me and my wife, it was what she lived for.  And she loved my wife as much as me.  In some families there are rueful jokes about mothers-in-law, but my mother would have sided with my wife if she and I had had a dispute.  My mother expected the best of me, and if I was on bad terms with my wife my mother would demand that I do better.

The other thing that my mother took seriously was nursing.  She absolutely loved it.  Partly out of compassion for the sick, partly because of the intellectual challenge, and partly because she was proud to follow in the footsteps of my grandmother, who is also a nurse.  My brother and I would go to our grandparents' house after school, and when my mother got done with work she would come to pick us up, and before leaving she would sit at the kitchen table and talk about patients and cases with my grandmother.  I learned a lot of science listening to those conversations.

No matter what else was happening in the family, my mother was the family health caseworker.  If I had to see a doctor for something, she could tell me exactly what the doctor would need to know about family medical history, out to second cousins and great-grandparents.  If my grandparents were in the hospital my mother was there watching them like a hawk.  My brother is still alive and with us because of the way my mother watched over him when he needed surgery several years ago.

And it wasn't just the family who was impressed by her nursing skills.  I'd like to read a tribute from a former co-worker of hers:
You Mom was such a caring person. It didn't matter where the person came from, why they were there, if they were injured, sick, or came up with something just to have attention. She treated all her patients with the same quiet, straightforward, caring.  
When I was in nursing school she mentored me. There are so many things that she taught me, that I still use 20+ years later.
...
 I also want you to know that your mom lives on in spirit through the many lives she touched. I am just blessed that one of them was mine.

She was such a blessing, so devoted, and I have much that I need to learn so that I can make it through life without her.

Statistics and Standardized Tests

I have posted a paper on the arXiv (a website for physics articles) addressing statistical issues in interpreting standardized tests.  This is a volatile topic, and my argument is long and nuanced, so I don't want to retype the entire thing in a blog post.  The short version is that a couple years ago somebody noticed that there are many successful scientists who did poorly on the GRE.  One possible interpretation is that the GRE has no predictive power for performance in a PhD program.  Another possibility is that performance is predicted by a combination of several variables, and a low score on any one of them might easily be compensated for by a high score on another.  Moreover, admissions processes typically enforce such a condition, so the only people getting in with low GRE scores probably did well by some other measure (e.g. research experience, relevant work experience, lab skills, etc.), while people who did poorly by some other measure must have had something to compensate (e.g. the GRE).  Consequently, when you compare people with high and low GRE scores, you aren't actually holding everything constant.  I use computer simulations to illustrate these points.

I also include a digression on "ought" vs. "is" statements, illustrated with two characters (Helena and Cosima) from Orphan Black, my current favorite science fiction show.  It may be that Helena is less likely to succeed in graduate school than Cosima is, but if Helena had a disadvantaged upbringing (and believe me, she did) then we ought to give her a chance to exceed our expectations.  This is an important point, given the diversity implications of standardized tests.

They were normal by the lights of their society

There's been much discussion of this picture of Auschwitz guards, taking some time off from their busy schedule of extermination to enjoy a little rest and relaxation.  The discussion has been of how normal they look, and I agree, they do look normal.



But I'll go one step farther:  Unlike today's neo-Nazis they do not look like members of a fringe group.  They look like cheerful, well-assimilated members of their society, people who are wholly in-tune with the widespread assumptions shared by all Right-Thinking members of their society.  Were they alive today they'd be popular people, sharing this photo on Instagram and getting "likes."  They'd be respectable people who don't question conventional wisdom.

I don't fear that Nazis, as such, will ever return to power.  There are indeed neo-Nazis in our society, and they can do a lot of dangerous things, but they will never consolidate power again.  Not in that form.  Yes, there's a neo-Nazi sympathizer in the White House, but his impeachment and removal is an inevitability at this point.  He will soon enough be toppled.  His followers might riot, they might do a lot of damage, they might kill innocents in retaliation, but as long as they carry Nazi flags they will never again gain true power.  That might seem like small consolation, given the harm they could nonetheless do, but it's an important consolation when one considers the power that they'd have if they controlled the resources of a modern nation-state.

That's not to say that the bad guys will never again hold power.  Of course they will.  By some lights the very definition of a "bad guy" is "a person in power."  But the neo-Nazis of today are fringe losers, and their label is far too toxic for mainstream acceptance.

No, the type of evil that the Nazis represented will only return to power by adopting a form that is not so frightening to the well-adjusted majority.  Now that the swastika has (accurately) been emblazoned on our cultural memory as a symbol of purest evil, no successful movement will ever again use it.  The next time an evil that great gains power, they will use some other symbol, a symbol that a decent person who desires social acceptability might come to embrace.  The bad guys might start off with mostly just fringe losers in their camp, but they will go mainstream in order to win, and then they will purge the losers.  Hitler did exactly that.  He rose to power on the backs of fanatical street-fighting men, creepy losers, then he got wider popularity, gained power, and purged many of the creepy losers.  That's what made him dangerous:  Once he had power he availed himself of the sorts of mainstream people who know how to make trains run on time, run munitions factories, raise and organize armies, and keep the economy humming to support the construction of that deadly war machine.

I want every Right-Thinking Person to reflect seriously on this.  The original Nazis, the ones who helped Hitler when he was small potatoes, they looked nothing like the people in that picture.  But once Hitler had power he was able to make use of normal, socially well-adjusted people who could fit in and conform to the society around them.  The sorts of people who could get out of bed on time, show up to work, make things happen, feel secure in the knowledge that they are in harmony with all of the other respectable people around them, and then at the end of a long week of mass murder go blow off some steam with other well-adjusted members of their society, taking group photos of smiling people at a party.

Question authority.

All of this has happened before and will happen again

Higher Superstition, Chapters 6-9

I paid less attention in these chapters.  I think Gross and Levitt started off with a fair point in chapter 6, on environmentalism:  Romanticizing non-Western cultures or ancient civilizations is a really bad idea.  Rejecting science while searching for solutions to environmental problems is just plain dumb.  To the extent that environmentalism is pursued as an ideological project, as opposed to applied science that takes into account human factors (and ideologies pretty much always over-simplify human factors wrong), such anti-scientific perspectives are just plain dumb.

Gross and Levitt go too far, however, when they go after scientists who take alarmist stances.  If this were a book on strategies for communication, I would probably agree with most of what they say against alarmism.  However, this is a book on anti-scientific attitudes, not un-scientific attitudes.  A scientist who exaggerates his or her findings is not doing good science, but they certainly aren't acting with animus toward science.  If anything, they are making the pedestal too high, not toppling it.  There are any number of valid criticisms to make against alarmists, but the alarmist is NOT rejecting scientific data.  There's a difference between rejecting science and abusing it with fanatical excess.  Environmental alarmism by scientists does not belong in a book on postmodernist and sociological critiques of science.  Alarmists are NOT saying "Science is just, like, your opinion, man."  Quite the opposite.

Also, the Gaia types lost.  Public pitches for environmentalism in America today are overwhelmingly dominated by appeals to science.  Somebody somewhere might be saying "Technological society is just a damaging Western construct based on scientific knowledge that poses as objective while in fact being a produce of heteropatriarchy..." but that person has no influence outside of their book club.

Chapter 7 covers a number of miscellaneous topics, among them AIDS and Afro-centric science.  I won't defend every statement made by every AIDS activist ever, but to my knowledge most of them criticized science from a place of frustration with the slow pace of good science, not from a place of rejecting scientific knowledge.  Even if some individuals adopted some anti-science rhetoric, it clearly was coming from a desire to speed up science, not replace it.  I would not have placed them alongside the postmodernists or the gender essentialists.

Afro-centric curricular with false historical claims about the scientific feats of African civilizations are a different matter, and tend to also blend in much of the same cultural relativism ("Science is just a Western way of looking at the world...") as many of the other targets of Gross and Levitt, albeit with appeals to different texts.  Gross and Levitt were fair here, and perhaps the best evidence that they were fair is that they also singled out a place where Afrocentric curricula are correct:  The first known example of steel production was in Tanzania 2,000 years ago.  It's worth noting the paradox of asserting, on the one hand, that ancient civilizations accomplished amazing innovations in science and technology, and on the other hand that science and technology are just arbitrary Western constructs.

Chapters 8 is on why people believed in the various sociological and philosophical critiques of science.  The basic conclusion of Gross and Levitt is restlessness with a Western society that failed to fix the problems people hoped it would fix.  I think that restlessness is indeed at work, and is also the source of many edufads.   People want a fix, and they want to rebel against whatever isn't delivering it.

Chapter 9 is on whether any of thtis matters.  They believed that it did.  They contended that it would lead to a schism between STEM and humanities (with social science probably being torn in two), with the revolt being led by STEM faculty.  That's not what happened, however.  Administrators put STEM on the pedestal because of grant money, but also pushed on us to deliver it (making many tenure-track jobs effectively into grant-writing jobs) and to take in more students rather than weeding out students.  We didn't tell the humanities faculty to shove it, the administrators did.  And they didn't do it in response to the postmodernists.  They would have just as easily pushed aside conservative defenders of the traditional Western Canon, and probably faster (in the name of diversity).

They argued that this will lead to the debasement of science education, but the people who have done the most to weaken science education are the people pushing edufads at the highest levels, and the people who have declared it a political imperative to get every available warm body into STEM.  Keynes was right about practical men being slaves of defunct intellectuals, but it doesn't follow that every defunct intellectual will enslave a generation of practical men.

They argued that it will debase public discourse, but ultimately it's not the left that did the most to weaken science in public discourse.  The left has much to answer for in the politics of the outside world, including misunderstanding and misusing science in certain cases, but the left has NOT tried to dethrone science.  If anything, lefty technocrats have elevated science above its station, ignoring the is/ought distinction.

Why were they wrong?  I think they were wrong because they over-estimated the power that humanities professors have over the next generation.  As I said above, one must not over-state Keynes' observation on the power of intellectuals.  Dethroning science was never an interesting project for Gen X, coming of age as the internet did.  Science kept improving things for us; why would we take up torches and pitchforks at the behest of our comparative lit profs?  Instead, we made the mistake of listening to the other idea-pushers, the ones insisting that we'd soon face a STEM shortage.  And the final result of that was to make traditionalists like me so pissed off that I've spent two and a half years reading and blogging about humanities and social science.

The real enemy we face now is a technocratic class that somehow rejects meritocracy.  Hey, I don't get it either.  But they see stubborn social problems and believe that we can fix it by defining away merit in STEM education.

Strange times.

Higher Superstition, chapter 5: Gender

Chapter 5 is about feminist critiques of science.  To the extent that feminists critique the culture of scientific workplaces I freely agree that there is much that is worthy of criticism, much to work on, and much more to be done.

To the extent that feminist critics have gone after scientific knowledge, I would say the following:
1) When people like Sandra Harding offer up essentialist arguments for why some particular idea in the basic sciences is more "masculine" or more "feminine", I think they are not only wrong but dangerous.  There's no distinct female perspective on chemical bonding or thermodynamics or electromagnetic waves.  To argue that there is risks bringing in the idea that women and men have different comparative advantages in the basic sciences.  That idea is not only devoid of empirical support, it is also an open door to justifying gaps and discrimination.  Many feminists have thus rejected essentialist arguments, and justifiably so.

2) When feminist critics raise concerns about the topics chosen by applied scientists, I think they have a better argument, at least in some fields.  There's no distinctly feminine viewpoint on quality control in chemical synthesis or optimizing the design of fiber-optic networks, but perhaps if there had been more women in biomedical research sooner then it wouldn't have taken so long for the medical community to recognize that heart attack symptoms in women are often (not always) different from those that are most common in men.  It's not about whether women or men are more qualified to analyze the data or perform the medical procedures (it's obvious that women and men are equally qualified to work in medical research), it's that much research begins with an anecdote (since every hypothesis lacks proper support before it's tested) and female clinical researchers might notice certain patterns in anecdotes from patients.  (Just as male clinical researchers might notice certain patterns in anecdotes.)

Similar things could be said about other areas of medical and behavioral research.  Female engineers working on consumer products might pay a bit more attention to, say, differences in average body size, differences in typical user experiences, etc.

A harder issue is the tendency to favor the use of male mice in biomedical research.  I've heard many female biomedical researchers defend this practice, on the grounds that the reproductive cycle in female mice lasts only 4 days, so there's much more variability in their physiology over the course of a study.  If one takes seriously the notion that female physiology matters, then it matters that female mice are more variable so the data will be noisier.  With resources being finite (raising and handling mice takes time and money, as does tracking their reproductive cycles so the data can be properly analyzed) it makes sense that many studies should be done first with male mice to get some preliminary data.  But if you really want to generalize to humans, and you aren't studying a male-specific question, then at some point you need to study female mice.  There's a difference between justifying greater use of male mice and justifying exclusive use of male mice.

But, of course, this is something where the funding agencies need to get more blame than the people working in the trenches with limited budgets.

So my take on this chapter is that Gross and Levitt start off strong but go too far in rejecting feminist critiques.  They need to keep in mind the distinction between pure and applied research.  There's no distinct feminine perspective on arterial plaque, or even a female perspective on molecular mechanisms of cervical cancer, but life experiences will matter when evaluating clinical anecdotes that might lead to the formulation of working hypotheses, and certainly the technology used in cervical cancer treatment should be designed with input from women who actually undergo such procedures.

Similar things can be said about race.  There's no distinct ethnic/racial perspective on statistical analysis in a clinical study, but one's experiences might affect whether one notices certain lifestyle patterns in different racial/ethnic/economic groups, and that matters when formulating hypotheses.  Ethnic diversity surely matters on an engineering team working on facial recognition software, as shown by some unfortunate examples with consumer products.

Mind you, there's a difference between research and practice.  I've been examined by competent female health professionals for some male-specific problems, and if I had a skin disease I'd be happy to go to a dermatologist of any ethnic/racial background.  Race and gender need not affect a conscientious professional's competence to apply existing knowledge in practice, but life experiences might affect the hypotheses that one frames in research. The testing of hypotheses is or ought to be an objective matter, but the choice of a hypothesis is highly subjective, and perspective matters.
