Misc Thoughts . . .

I'm subscribed to Greenwald and Taibbi. I haven't felt this good about being a liberal in more than a decade.

I have serious difficulty dealing with people dying from Trump Derangement Syndrome, all convinced that I am a committed Trump supporter. I'm opposed to the Far Left which styles itself Progressive, and claims it's the same thing as liberal. It is fundamentally illiberal.

A friend is a committed Christian and committed Trump supporter. He sent me a message asking if I knew what 2020 divided by 666 was. I did the math in my head, knew the answer instantly. It's 3.0330. I replied that I had no idea that God was limited to Base 10. He's furious. Just assume for a second that there is a God. Why would he ever use Base 10? Binary or Base Eight is infinitely more sensible.

As you know, there are 10 kinds of people: Those who understand binary, and those who don't.

Time to Revise the Math Curriculum?

I heard Steve Levitt (from Freakonomics fame) discuss this issue on an episode of his new podcast, "People I Mostly Admire." Here's the proposal for changing the high school math requirement for most of us. This is from an organization to which Levitt belongs, 21CMath.org:

We surveyed 900 “Freakonomics” podcast listeners — a pretty nerdy group, we must admit — and discovered that less than 12% used any algebra, trigonometry or calculus in their daily lives. Only 2% use integrals or derivatives, the foundational building blocks of calculus. In contrast, a whopping 66% work with basic analytical software like Microsoft Excel on a daily basis.

When was the last time you divided a polynomial? If you were asked to do so today, would you remember how? For the most part, students are no longer taught to write cursive, how to use a slide rule, or any number of things that were once useful in everyday life. Let’s put working out polynomial division using pencil and paper on the same ash heap as sock darning and shorthand.

What we propose is as obvious as it is radical: to put data and its analysis at the center of high school mathematics.

Blind Orchestra Auditions Alleged to Be Unfair Based Purely on Optics

I'll open this article with a tweet by "The Science Femme, Woman in STEM":

Blind auditions were introduced in order to focus on talent, not what a musician looks like. In his book, Blink: The Power of Thinking Without Thinking, Malcolm Gladwell celebrates blind auditions:

The world of classical music – particularly in its European home – was until very recently the preserve of white men…But over the past few decades, the classical music world has undergone a revolution…Many musicians thought that conductors were abusing their power and playing favorites. They wanted the audition process to be formalized…Musicians were identified not by name but by number. Screens were erected between the committee and the auditioner, and if the person auditioning cleared his or her throat or made any kind of identifiable sound…they were ushered out and given a new number. And as these new rules were put in place around the country, an extraordinary thing happened: orchestras began to hire women. [pp. 249-250]

Musician and educator James Boldin concurs."The ability of even highly trained musicians to make split-second evaluations of a player’s skill is compromised [by the way they look]."

In the referenced NYT article dated July 15, 2020, writer Anthony Tommasini urges that blind auditions are not fair ("The status quo is not working"), because (he argues) there are not enough Blacks playing for major orchestras. It is stunning that Tommasini makes this allegation of impropriety without offering any statistics showing the extent to which Blacks listen to classical music while growing up, the extent to which they aspire to be classical musicians or the extent to which they apply to and graduate from classical music programs. Why has he failed to tell us the extent to which Blacks aspire to be classical musicians?  These numbers (which I haven't been able to track down) bear strongly on what I think about Tommasini's numberless conclusions.  If Blacks, as a percentage of the population, are less interested in classical music, the small numbers of Blacks in major orchestras might reflect that lack of interest in classical music, not anything nefarious.

Tommasini argues "over the past century of increasingly professionalized training, there has come to be remarkably little difference between players at the top tier."  He is arguing that there is so little difference among the musicians in the top tier that they are all good and there is thus no need for auditions. Apparently, according to Tommasini, orchestras should should simply assemble the musicians that are merely passable, then completely dispense with the meritocracy.

American culture is at an intense impasse. Many of us strongly believe that professions ought to be staffed by those who are best at doing the tasks demanded by the profession. Most of us want the best possible surgeon operating on our children and we want the best pilots flying our airplanes.  Increasingly, however, other people are making arguments that there is something wrong with any profession where the practitioners are not representative of society as a whole. They argue that bad optics constitute a prima facie case of unfairness.  I strongly disagree with the latter viewpoint unless it can be shown that participants are being excluded because because of the way they look.

When I attend classical concerts (I attend about one per year), I notice that the percentage of Asian musicians is much bigger than the general population of the U.S.  I assume that Asians* are "overrepresented" because they have more interest in classical music than the population at large.  This article from 2012 sets forth the numbers offered by Slate:

Asians make up just over 4 percent of the U.S. population, but 7 percent of U.S. orchestra musicians are Asian, and the figure rises to 20 percent for top orchestras such as the New York Philharmonic. At the elite Julliard School for music, one in five undergraduates—and one in three Ph.D. students—is Asian.

I have never seen any evidence that there is a pro-Asian hiring bias by orchestras.  I assume that Asian musicians excel at blind auditions because they make better-sounding classical music according to the people who hire classical musicians.

Why did Tommasini fail to interview those who hire musicians for major orchestras as part of his article?  Is it possible that those who do the hiring would A) argue that even at the highest levels of performance, there are noticeable differences in music quality among professional musicians, and B) they support blind auditions because this allows them to hire solely on the quality of the music?  I wonder even more, why would a person who hires musicians for a professional orchestra consider stepping into the current maelstrom of Wokeness in which Tommasini indulges by stating, on the record, that they hire the best musicians blindly, thereby putting targets on their backs for attacks based on implied or institutional racism? What would those who hire classical musicians have to gain by contributing to this type of article, which declares unfairness without considering extent of interest in classical music by the various demographic groups? Without this information, this type of article written by Tommasini is a cheap shot based upon innumeracy (or worse) and one-sided evidence.

I choose my own music based on sound. I rarely know what the instrumentalists look like when I listen to new music on internet "radio."  I like what I like and I could care less what the musicians look like. Blind auditions sound like a good idea for me because I do it all the time when I hear new music and then make an intuitive judgment as to whether I like that music.

I believe that the NYT needs to be avoid assuming that there is something wrong just because membership in a profession doesn't reflect the population at large. This argument, which is increasingly putting the focus on every profession, and which claims that every profession and college class must be representative is growing into an obsession these days. Where else should we apply it?  Is there something wrong when those who are gospel choir singers, professional football and basketball players, jazz musicians and hip hop musicians lack the proportion of whites (or Asians) that one finds in the general population?  The logic applied by the NYT article is the same logic that would conclude that police officers are sexist because 73% of people arrested in the U.S. are men. Men are arrested more often because then commit more crimes than women.  Why aren't there more men teaching kindergarten?  Why are there not more women car mechanics?  Why are only 43% of college students men? It is not surprising that demographics of every group don't represent the U.S. population at large.

I applaud organizations that take a special interest in offering education and training to Blacks who aspire to become professional classical musicians. It would be great if everyone who is interested in classical music had the opportunity to be exposed to that genre along with opportunities to perform and excel.

*I don't like to use the term Asians, in that it awkwardly and crudely lumps together people from many different countries.  But this is the term used by the Slate article.  I also consider it destructive to lump people into the cartoonish categories of "black" and "white."  See also here.  I need to also make it clear that while I think racial categorization of any type of pernicious, I am aware that bigotry exists in many places--many people do categorize others in these ways and discriminate against them based on these categories. Wherever bigotry exists, it should be vigorously prosecuted and socially condemned.

Hear No Facts, See No Facts.

At the Wall Street Journal, Ayaan Hirsi Ali writes that many of the most vocal players in our re-energized race debates are incentivized to maintain conflict rather than seeking solutions. I have seen what Ali has seen about the the resistance to facts and statistics when these things are inconvenient to the narrative of choice by those supporting the Black Lives Matter political agenda (which is separate and distinct from the idea that Black lives do, of course, matter). Whenever there is such a disconnect between narrative and evidence, that is a big red ultra-suspicious flag.

Here are a few dozen other issues and facts courtesy of Sam Harris (Making Sense Podcast Transcript: "Can We Pull Back From the Brink") that the reform movement not only ignores, but intensely refuses to consider. Why doesn't BLM's website take a careful look at available statistics regarding policing on its website?  If it did, BLM would find significant support for the claim that police harass Blacks more often than non-Blacks, but they would not find evidence that police use lethal force against Blacks disproportionately.

If the people insisting on reform refuse to first discuss the facts on the ground--a vigorous exploration the facts, pro and con--why should the rest of us--the country at large--trust that movement?

Here is an excerpt from Ali's WSJ article:

Although I am a black African—an immigrant who came to the U.S. freely—I am keenly aware of the hardships and miseries African-Americans have endured for centuries. Slavery, Reconstruction, segregation: I know the history. I know that there is still racial prejudice in America, and that it manifests itself in the aggressive way some police officers handle African-Americans. I know that by measures of wealth, health and education, African-Americans remain on average closer to the bottom of society than to the top. I know, too, that African-American communities have been disproportionately hurt by both Covid-19 and the economic disruption of lockdowns.

Yet when I hear it said that the U.S. is defined above all by racism, when I see books such as Robin DiAngelo’s “White Fragility” top the bestseller list, when I read of educators and journalists being fired for daring to question the orthodoxies of Black Lives Matter—then I feel obliged to speak up.

The problem is that there are people among us who don’t want to figure it out and who have an interest in avoiding workable solutions. They have an obvious political incentive not to solve social problems, because social problems are the basis of their power. That is why, whenever a scholar like Roland Fryer brings new data to the table—showing it’s simply not true that the police disproportionately shoot black people dead—the response is not to read the paper but to try to discredit its author.

I have no objection to the statement “black lives matter.” But the movement that uses that name has a sinister hostility to serious, fact-driven discussion of the problem it purports to care about. Even more sinister is the haste with which academic, media and business leaders abase themselves before it. There will be no resolution of America’s many social problems if free thought and free speech are no longer upheld in our public sphere. Without them, honest deliberation, mutual learning and the American problem-solving ethic are dead.

Being Bad at Math Gives Us Freedom

Math proficiency is a superpower that allows us see into the future and to understand the past. Only 41% of our 4th graders and 34% of 8th graders are math proficient.

Being BAD at math gives people the freedom and confidence to say things that are blatantly untrue with a straight face. Being BAD at math gives us the super-power to laugh at those who have carefully proven their cases with math. Being bad at math gives us the super-freedom to "prove" complex claims with mere anecdotes.

Every day it becomes clearer to me that our innumeracy explains much of our country's rampant dysfunction.
