Men And Women

An interesting discussion on sex differences, spurred by the Google kerfuffle.

It is very important to the Left to minimize them. This is one of the several areas in which they are not the “party of science.”

[Update a few minutes later]

Here’s sort of the tl;dr:

This seems to me like the clearest proof that women being underrepresented in CS/physics/etc is just about different interests. It’s not that they can’t do the work – all those future math teachers do just as well in their math majors as everyone else. It’s not that stereotypes of what girls can and can’t do are making them afraid to try – whatever stereotypes there are about women and math haven’t dulled future math teachers’ willingness to compete difficult math courses one bit. And it’s not even about colleges being discriminatory and hostile (or at least however discriminatory and hostile they are it doesn’t drive away those future math teachers). It’s just that women are more interested in some jobs, and men are more interested in others. Figure out a way to make math people-oriented, and women flock to it. If there were as many elementary school computer science teachers as there are math teachers, gender balance there would equalize without any other effort.

I’m not familiar with any gender breakdown of legal specialties, but I will bet you that family law, child-related law, and various prosocial helping-communities law are disproportionately female, and patent law, technology law, and law working with scary dangerous criminals are disproportionately male. And so on for most other fields.

This theory gives everyone what they want. It explains the data about women in tech. It explains the time course around women in tech. It explains other jobs like veterinary medicine where women dominate. It explains which medical subspecialties women will be dominant or underrepresented in. It doesn’t claim that women are “worse than men” or “biologically inferior” at anything. It doesn’t say that no woman will ever be interested in things, or no man ever interested in people. It doesn’t say even that women in tech don’t face a lot of extra harassment (any domain with more men than women will see more potential perpetrators concentrating their harassment concentrated on fewer potential victims, which will result in each woman being more harassed).

It just says that sometimes, in a population-based way that doesn’t necessarily apply to any given woman or any given man, women and men will have some different interests. Which should be pretty obvious to anyone who’s spent more than a few minutes with men or women.

Yup. But do read the whole thing, because it also describes just how toxic and (ironically, given the “punch a Nazi” commentary) fascist the environment in the industry has become.

The most common error in reporting on the Google memo:

To object to a means of achieving x is not to be anti-x.

The failure to apply that same logic to the author of the memo is straightforwardly frustrating for those who agree with many of the views that the memo expressed. And it should also frustrate those who disagree with the author but care about social justice.

Every prominent instance of journalism that proceeds with less than normal rigor when the subject touches on social justice feeds a growing national impulse to dismiss everything published about these subjects—even important, rigorous, accurate articles. Large swathes of the public now believe the mainstream media is more concerned with stigmatizing wrong-think and being politically correct than being accurate. The political fallout from this shift has been ruinous to lots of social-justice causes—causes that would thrive in an environment in which the public accepted the facts.

Given that many of their goals are actually terrible, I’m glad they continue to screw up like this.

The Google memo exposes a libertarian blind spot.

Megan McArdle: As a woman in tech, I realized that these are not my people:

Thinking back to those women I knew in IT, I can’t imagine any of them would have spent a weekend building a fiber-channel network in her basement.

I’m not saying such women don’t exist; I know they do. I’m just saying that if they exist in equal numbers to the men, it’s odd that I met so very many men like that, and not even one woman like that, in a job where all the women around me were obviously pretty comfortable with computers. We can’t blame it on residual sexism that prevented women from ever getting into the field; the number of women working with computers has actually gone down over time. And I find it hard to blame it on current sexism. No one told that guy to go home and build a fiber-channel network in his basement; no one told me I couldn’t. It’s just that I would never in a million years have chosen to waste a weekend that way.

These people don’t realize the degree to which their ideology is blinding them to reality. And they don’t realize the degree to which their behavior harms their own cause:

…you still have to ask whether shamestorming Damore and getting him sacked was really the best way to convince him — or anyone else — that he’s mistaken. Did anyone’s understanding of the complex quandaries of gender diversity advance? If there were guys at Google wondering whether the women around them really deserved their jobs, did anyone wake up the morning after Damore’s firing with the revelation: “Good God, how could I have been so blind?” No, I suspect those guys are now thinking: “You see? Women can’t handle math or logic.”

And as always, the Left is impervious to irony.

Leftists: We worship science, except when we don’t.

Google has done a horrible thing to its employees, especially its snowflakes:

Google’s monoculture has turned these employees into snarling, hate-filled, censorious little thought-police who live under the misapprehension that their seething rage is virtue. It reminds me of what happened in the Soviet Union when neighbor turned in neighbor to ensure the regime believed in their loyalty to the Right Ideas.

And they are incapable of seeing it.

I may follow Roger’s advice to start using Dogpile. But I’ll have to wean myself from Chrome, because it makes it hard to automatically use other search engines.

Eclipses

feel weird.

I wonder if the breaking down in tears is a current phenomenon, or if it’s traditional from when most people didn’t know what was going on, and thought it was the end times?

I disagree with this, though:

…for an eclipse with specific properties (such as total versus partial, long versus short, and tropical versus arctic) to make a repeat appearance in any particular region, one has to wait while eclipses work their way around the world like a set of gears, which requires three Saroses—a length of time equal to fifty-four years and around one month, or, more precisely, thirty-three days. Because this surpasses human life expectancy in that era four thousand years ago, it’s astonishing that the cycle was noticed at all.

Only if you don’t understand that life expectancy is an average, with a high standard deviation. Many, and particularly ancient astronomers, would have likely lived much longer than average.

We were in Denver over the weekend, and went up to Wondervu Saturday might for a meeting of the Sky Watchers club (invited by Leonard and Barbara David, who have a place up there in the mountains above Boulder). One of the lecturers (retired from the National Renewable Energy Lab in Golden) gave a talk on NREL’s analysis of probability of not having clouds along the entire path. He had seen the one in Aruba in the ’90s, and he and most of the people there planned to go up to Casper to see it. I’d like to, but I can’t justify time/money right now.

Planetary Protection

There may be some useful changes coming to NASA:

JPL has butted heads with the office over the next big mission, the Mars 2020 rover, which will gather rock samples for later retrieval to Earth. JPL is interesting in having the rover target areas with subsurface brines, an activity that would not be allowed with its planned level of cleanliness. Moreover, the planetary protection office has not yet agreed on the efficacy of the techniques JPL will use to sterilize the tubes in which the rover will cache rock cores. If the issues aren’t resolved, Rummel says, the rover could be headed for a bureaucratic “train wreck”.

The office, which has always been limited by a small budget and staff, continues to gauge a spacecraft’s “bioburden” based on a classic measure—the number of cultivable microbial spores it carries. “Some of the numbers we’ve been operating on date back decades, and it’d be great to revisit them,” says Sarah Johnson, a planetary scientist at Georgetown University in Washington, D.C. She thinks the office should take advantage of two innovations: chemicals that can separate DNA from dead and living cells, and genomic sequencers that can classify the living ones by type. Scientists could then, for example, assess their individual likelihoods of surviving on Mars.

As a member of the Curiosity team, Johnson would like to see a change in policy that would allow the rover to sidle up to the wet streaks to give them a close look, even if the drill itself—currently on the fritz since December 2016—could not be used. In their op-ed, Fairén and his colleagues go further, saying NASA should slightly lower its sterilization standards so that robots as clean as Curiosity could explore special regions. Fairén says there is growing evidence that the harsh environment on the martian surface—a combination of frigid temperatures, caustic chemicals and deadly cosmic radiation—would kill Earth’s microbes quickly, especially in the limited numbers that ride along with robots. Even if some survive, he adds, future missions could distinguish between earthly and martian microbes by sequencing their genomes.

As the article notes, it’s inevitable that humans are going to go there. If they want to look for non-terrestrial life, they need to start doing it now.

Lunar Cryonics

I accidentally started a Twitter conversation with Sandy Mazza as a result of this nice piece on markets being enabled by lower-cost launch, including space burial. I noted to her that it made no sense for the California Department of Public Health to be regulating it, and then mentioned that they shouldn’t have anything to do with cryonics, either. In the course of the discussion, I dug up an old piece I wrote for Cryonics Magazine back in 1990 (ctrl-F “Simberg” to find it). Given that things are finally looking promising for reducing cost of access to space in general, and likely the moon as well, I decided I’d resurrect it here. Note that I’ve been talking about the need for markets to drive down launch costs for three decades. Note also that it’s somewhat dated, in terms of its discussion of the NASP and American Rocket.

Vegan Diets

and the brain:

Removing refined carbohydrates, such as sugar, flours, fruit juice, and cereals, makes ANY diet healthier. This is the most likely reason why plant-based diets appear healthier than meat-based diets in some clinical studies. All of the studies I’m aware of claiming that plant-based diets are superior to omnivorous diets suffer from the same tragic flaw. Researchers conducting these studies NEVER simply ask people to remove animal foods from their diet. They always change more than just that single variable—such as lowering fat content or adding exercise—and they always instruct people in the plant-based group to eliminate refined carbohydrates and processed foods. In almost every case, these special “plant-based” diets are then compared to a junky omnivorous diet loaded with sweets, baked goods and manufactured foodstuffs.

This is not a fair fight. How do we know whether it was the removal of the meat, refined carbs, industrially-produced oils, or artificial additives that was responsible for the benefits? I’ve engaged in countless social media conversations with plant-based diet experts in which I politely ask for scientific evidence that simply removing animal foods from the diet—without making any other changes—results in health benefits. None of them have ever been able to cite a single article for me.

The amount of junk science in nutrition studies is just appalling.
