John Tierney guest stars on xkcd

John Tierney thinks that women just can’t measure up to men when it comes to math and science.  His column is infuriating, but I’ll let Female Science Professor, Dr. Isisdana at EotAW, and PZ Myers take it apart for me.

FSP summarizes the article snarkily and succinctly:

There are flawed studies that show that females and males have similar quantitative skills and better studies that show that more males than females are extremely talented at math. This is one reason why men are more successful in math, science, and engineering. If women were good at math and science, perhaps they would understand these scientific studies with all the numbers in them.

Dr. Isis does a hot little data dance in the holes in his arguments, like so:

He then continues to outline the evidence that boys tend to be the top scorers in math and science when measured via standardized aptitude tests, even if there is no difference between the means.  Yet, he clearly has ignored the fact that this phenomenon is unique to the United States.  Indeed, in countries with more gender equal cultural norms, the divide disappears.  In Iceland, girls out perform boys in math and science.  Japanese girls out perform American boys.

Dana at EotAW, my favorite philosopher feminist, points out some logic issues:

This argument apparently only works for math. If we’re talking at the level of the facts people normally pull out here, there’s some research that suggests that at the tip of the tail, the brightest men are better at math than the brightest women, and the usual argument proceeds from here to conclude that this explains why men are more likely to be PhD’s in math, etc.  But similar research shows that the best female communicators are better than their male counterparts, and that women are natural consensus builders and yet no one suggests that top literature and political science departments are and should be female-dominated, because here we can easily see that innate tendencies can be overrun by other factors.

And PZ Myers uses the same reasoning as Tierney to show that we should be using wealth to determine who gets the best jobs in science:

By the same reasoning, we can also argue that wealth differences in abilities should not be dismissed, since they tend to be perpetuated over many generations. We can just stop wasting time and money trying to educate poor children or correcting the inequities of poverty in our schools, because the data clearly says that it’s highly unlikely that any of them will succeed in science.

Since there is far too much awesomeness to copy/paste, I advise a quick visit to FSP, Dr. Isisdana at EotAW, and PZ.

In honor of Isis the Scientist, who inspires scientists to combine hot shoes and differential equations, I present the shoes I’m wearing to show off my gorgeous new data today:

Early women scientists were awesome, but they sure had to put up with a lot.  This description of Wanda G. Bradshaw says a lot about the times – she isn’t even allowed interests separate from her husband.

The MSM contributed too much to the misinformation about health care reform by misrepresenting poll results.

Including transportation costs would go a long way towards realistically representing housing affordability: 69% of communities are considered affordable using the standard measure of 30% of income, but only 39% are affordable (less than 45% of income) if housing and transportation costs are considered.

A few weeks ago, a friend told me he was coming over with a book that I absolutely had to read.  He showed up a few minutes later and launched immediately into a rapturous description of The Wild Trees. He wouldn’t even visit very long so that I could start reading right away.   I didn’t start reading right away and that’s a good thing – I had a test the next day and once I started reading, I couldn’t stop.

From the Institute for Redwood Ecology

The Wild Trees is about redwood research and the people that pioneered the field.  Until very recently, we had no idea what was up there and a lot of it is still a mystery.

I love popular science books, but I usually find them simply intellectually exciting and rarely get emotionally involved.  This book was different for a few reasons.  First of all, the scientists are portrayed as humans and the way their personal lives influence their professional lives (and vice versa) is a large part of the book.  So often scientists are portrayed as dull or unnaturally obsessed, but this book shows how very human we are – from the connections we have with our families, to breakups and sex, to the awe and wonder we feel when presented with something so incredible as a redwood.

And that’s the second reason this book is so different from the normal nonfiction I read: a lot of time was spent describing the trees, the forest, and the experience of climbing the trees so that their magnificence and beauty really came through.  By the end of the book, I was ready to sign up for a tree climbing class just so I could see for myself what was up there.

It was also kind of thrilling to have a sort of connection to these trees.  I work with a scientist who studies redwoods and he has cores from many of these trees.  To get a core, you use a special hollow drill to extract a bit of wood the size of a very, very long straw from a tree.  You can sand the straw flat to see the growth rings:

Redwood rings under a microscope

I don’t study redwoods now, but I learned all about dendrochronology, or tree ring science, with redwoods.  Tree rings are a fascinating archive of stress, climate, competition, and more – an autobiography of a tree, if you will.  The language may be hard to interpret, but the information is there.

Every tree that is cored is given a name and most of the time the names are dull (SP032, for example).  But redwoods are given names like Thor, Atlas, and Kronos.  I always gave the tree a personality I associated with that name as I counted and counted and counted (and counted and counted) the rings.  The Wild Trees describes the discovery of many of the trees whose cores I analyzed and what it was like to climb them, what fascinating communities live within their canopies, even human drama that occurred in their branches.  I feel honored and grateful to have learned to read the stories trees tell from such ancient and stately behemoths.

Religious bastards in Virginia are handing out tracts telling women that the way we dress causes rape.  Those people should be arrested.  Or kicked in the face.

I’m always amazed by studies that show how easy it is to manipulate people’s views. Then I start wondering how I can take over the world.

Agricultural subsidies need some serious rethinking: first the government pays to make unhealthy food cheap, then it pays for obesity related disease through health care.

Maybe the problem with Toyota isn’t Toyota, but elderly drivers.

Science is getting way better at reading minds.

A very fun post on autoantonyms for all the word lovers.

From Karen Armstrong’s A History of God: The 4,000-Year Quest of Judaism, Christianity and Islam:

Science demands the fundamental belief that there is a rational explanation for everything; it also requires an imagination and courage which are not dissimilar to religious creativity.  Like the prophet or the mystic, the scientist also forces himself to confront the dark and unpredictable realm of uncreated reality.  … [T]he scientific vision of our own day has made much classic theism impossible for many people.  To cling to the old theology is not only a failure of nerve but could involve a damaging loss of integrity. The Faylasufs attempted to wed their new [scientific] insights with mainstream Islamic faith… Yet the ultimate failure of their rational deity has something important to tell us about the nature of religious truth.

Testosterone doesn’t actually make people selfish; it promotes fair play.

It’s not that feminists don’t have a sense of humor, you’re just not funny.

China really isn’t getting better about human rights abuses.

Fantastic essay by Asimov on “The Relativity of Wrong.”  I feel like this would be especially good to read in intro science classes.

Having health insurance doesn’t necessarily make healthcare affordable or accessible.

Large animal farms (actually large farms period) do incredible environmental damage with human victims.  Dairies in New Mexico have led to contaminated water in a region where water scarcity is a growing issue.

We thought flowering plants had such an advantage because of their flowers.  Actually, it’s their veins!

The Discovery Channel clearly doesn’t appreciate the women who watch their shows.  Otherwise why would they put out such offensive ads?

E.O. Wilson in Consilience: The Unity of Knowledge:

On the one side, ethics and religion are still too complex for present-day science to explain in depth.  On the other, they are far more a product of autonomous evolution than hiterto conceded by most theologians.  Science faces in ethics and religion its most interesting and possibly humbling challenge, while religion must somehow find the way to incorporate the discoveries of science in order to retain credibility.  Religion will possess strength to the extent that it codifies and puts into enduring, poetic form the highest values of humanity consistent with empirical knowledge.

The essence of humanity’s spiritual dilemma is that we evolved genetically to accept one truth and discovered another.

Oh so true snippets of fundie culture.

The Princeton Guide to Ecology just went to the top of my wishlist.  Yes, even above the lovely shoes I posted earlier this week.

“Government-run” health care has problems, but it still works better than private insurance:

Compared with the employer-coverage group, people in the Medicare group report fewer problems obtaining medical care, less financial hardship due to medical bills, and higher overall satisfaction with their coverage.

Conservatives freaked out about Obama’s speech encouraging kids to work hard in school, calling the action “unprecedented.”  I guess they weren’t paying attention during similar speeches given by Reagan and George H. Bush.  (Though perhaps if they’d paid better attention in school they would have developed some critical thinking skills and we wouldn’t have to deal with their craziness.)  I think the response of the right in this situation is very telling – they disagree with Obama, so they won’t listen to anything he says.  This is why Republicans have blocked health care reform at every turn, why Republicans have become the party of “no.”  I’m reminded of a child being told something she doesn’t want to hear who covers her ears and yells.

There isn’t much justice in our justice system.  How many innocent people have we executed?

The myth of overspending:

Whether families are spending more than they should according to some moral notion—consuming too much of the world’s resources or buying things they could easily live without—is not the issue at hand. These data give us no clue about the right amount of spending. But they give us powerful evidence that excessive consumption is not why families are going broke. There is no evidence of any “epidemic” of overspending—certainly nothing that could explain a 255 percent increase in the foreclosure rate, a 430 percent increase in the bankruptcy rolls, and a 570 percent increase in credit-card debt. A growing number of families are in terrible financial trouble, but despite the accusations, their frivolity is not to blame.

A lot of people claim that being queer is wrong because it isn’t “natural.” Weird how different cultures consider different sexualities “natural.”

Ecological/environmental refugees are becoming much more common.

A corporate sponsor of the Tea Party Express, many of whose members believe that health care reform is “a secret plot to kill old people”, is paying millions of dollars for killing old people.

A ton of feathers – why micro-inequities suck.
