Sex Differences
gregladen | June 1, 2015Bernie Sanders' famous essay is below. I will reserve comment but I'd like your opinion on it. I will say that the press is handling this rather badly, at least at present, taking quotes with zero context, not addressing the meaning of the essay as a whole. Sanders says it was poorly written. Is it?
Man and Woman
by Bernie Sanders
Mid-February, 1972
A man goes home and masturbates his typical fantasy. A woman on her knees, a woman tied up, a woman abused.
A woman enjoys intercourse with her man – as she fantasizes being raped by 3 men simultaneously.
The man and woman get dressed up on…
gregladen | November 18, 2014Of course they do. To the extent that genes make you anything in particular, though the role of genetics in human behavior is pretty limited.
You've probably heard about the newly reported research in which a genetic link was found to homosexuality in a study of gay brothers. Kelly Servick has a good writeup on it here. The study looked at 409 pairs of gay brothers, and found a region on the X chromosome that was similar across the sample. This sort of shotgun approach, comparing a trait (in this case, gayness) with a bunch of DNA (I oversimplify) is very likely to get results that look real…
gregladen | February 19, 2014Remember the Fall Olympics in Vancouver? That was the year that skaters ... not the racing ones but the dancing ones ... were falling all the time as if they had some kind of special extra slippery ice on the skating rink. Well, this year, at Sochi II, we are witnessing the Fall Olympics mainly on the snow slopes and half pipe, where lousy snow conditions, caused by warm conditions with some rain, have messed everything up.
But there is an interesting twist this year. According to a piece in the New York Times, women are being affected more than men:
...most of the injuries have been…
gregladen | August 12, 2013Whitey Bulger has finally been convicted of a small percentage of all the bad things he is said to have done. The Boston Globe has the details.
James J. “Whitey” Bulger, the notorious Boston gangster who rampaged through the city’s underworld for decades before slipping away from authorities and eluding a worldwide manhunt for more than 16 years, was convicted today in federal court of charges that will likely keep him in prison for the rest of his life.
Don't count on that. Whitey has slipped from the clutches of justice several times before. He'll probably make a break for it between…
gregladen | February 27, 2013Humans appear to have a great deal of variation in sexual orientation, in what is often referred to as "gender" and in adult behavior generally. When convenient, people will point to "genes" as the "cause" of any particular subset of this diversity (or all of it). When convenient, people will point to "culture" as the "cause" of ... whatever. The "real" story is more complicated, less clear, and very interesting. And, starting now, I promise to stop using so many "scare" quotes.
Fixed up and reposted.
Prior to birth there are a number of factors than can influence things like gender or…

In an old colonial-looking restaurant that served ten kinds of steaks, I met up with an experienced explorer and a local farmer, to have dinner and discuss plans for an upcoming research project that would be managed by The Explorer and that would partly be on The Farmer's land, which adjoined a rather extensive and remote wilderness area. I don't remember a lot about the conversation, but one memory of the evening stands out: That was when The Farmer, rooting around in a bag for some cash to tip the waitress, pulled out this big-ass gun ... a small cannon, really ... that was in the way.…
gregladen | November 27, 2012The title of this post is, of course, a parody of the sociobiological, or in modern parlance, the "evolutionary psychology" argument linking behaviors that evolved in our species during the long slog known as The Pleistocene with today's behavior in the modern predator-free food-rich world. And, it is a very sound argument. If, by "sound" you mean "sounds good unless you listen really hard."
I list this argument among the falsehoods that I write about, but really, this is a category of argument with numerous little sub-arguments, and one about which I could write as many blog posts as I…
gregladen | November 26, 2012Nature is a potential source of guidance for our behavior, morals, ethics, and other more mundane decisions such as how to build an airplane and what to eat for breakfast. When it comes to airplanes, you'd better be a servant to the rules of nature or the airplane will go splat. When it comes to breakfast, it has been shown that knowing about our evolutionary history can at times be a more efficacious guide to good nutrition than the research employed by the FDA, but you can live without this approach. Nature works when it comes to behavior too, but there are consequences. You probably…
gregladen | November 14, 2012The Gender vs. Sex question...referring to the meaning of those two terms in relation to each other...is standard material for discussion in Anthropology and related fields, but is often left unattended to in day to day discourse. Both terms have internal complexity, with Gender meaning something about people’s identity as well as being a linguistic term, different but overlapping, and of course, Sex is a verby noun sometimes. But when we say “Gender vs. Sex” we are clearly talking about biological things such as chromosomes and genitalia, behavioral things such as attraction and orientation…
gregladen | August 2, 2012One in three or four women in the United States will have been raped or seriously assaulted sexually by the time they reach a few decades in age. That will have been done by one or more men. Most people who are killed by another person are killed by a man. This is true whether the killing is legal or illegal. Very few people in Western society get through their entire lives without being affected either directly or nearly directly by some sort of violent crime of some kind or another, and that crime was almost always committed by a man. Wars are mostly fought by men, and are typically…
gregladen | December 17, 2011Sheril Kirshenbaum has a few comments about a piece in Science addressing innate differences between boys and girls in math. I have to say, it may be hard to accept the scientific truth sometimes, but the research really does consistently say the same thing again and again. In this latest study, the science ...
[doesn't] rule out the existence of very small biological difference, but, by comparing test scores across cultures, [does] indict local social factors as the likely primary culprit. Gender gaps vary from place to place, showing that cultural factors swamp biological ones.

gregladen | November 28, 2011If you read only one book this holiday season, make it all of the following twenty or so!
But seriously ... I'd like to do something today that I've been meaning to do, quite literally, for years. I want to run down a selection of readings that would provide any inquisitive person with a solid grounding in Behavioral Biological theory. At the very outset you need to know that this is not about Evolutionary Psychology. Evolutionary Psychology is something different. I'll explain some other time what the differences are. For now, we are only speaking of fairly traditional Darwinian…
gregladen | October 10, 2011The following photograph is a Facebook Peme (Pic Meme, sometimes spelled "peem"). In its original form it had a caption that was sexist and offensive, feeding the idea that girls can't do math (innately) and also suggesting that a good backup plan for a middle schooler frustrated with academics is sexual self-objectivictoin.
I've blogged about this at The X Blog. Here, I'd like to ask you to suggest alternative captions for this photograph. And by "alternative" I mean positive. Or funny but not sexist.
gregladen | August 22, 2011First of all, I want you to know that I've devoted my life to this blog post so now you have every reason to love it more than any other blog post. Sniff sniff.
Or, could it be that I've been watching too much America's Got Talent (which, clearly, it does not, except that yo-yo guy was pretty good). I mean, seriously, if America's Got Talent then why is there Country Western Music? Anyway, I have noticed this trend of the argument for Not Being Voted Off The Island being that I've Invested Myself Emotionally Beyond Belief and I think that's a bad trend.
Speaking of time, this was one of…
gregladen | July 8, 2011Humans appear to have a reasonable amount of diversity in their sexual orientations, in what is often referred to as "gender" and in adult behavior generally. When convenient, people will point to "genes" as the "cause" of any particular subset of th is diversity (or all of it). When convenient, people will point to "culture" as the "cause" of ... whatever. The "real" story is more complicated, less clear, and very interesting. And, starting now, I promise to stop using so many "scare" quotes.

gregladen | July 7, 2011Behaviors are not caused by genes. There is not a gene that causes you to be good, or to be bad, or to be smart, or good at accounting, or to like bananas. There are, however, drives. "Drives" is a nicely vague term that we can all understand the meaning of. Thirst and hunger are drives we can all relate to. In fact, these drives are so basic, consistent and powerful that almost everyone has them, we share almost exact experiences in relation to them, and they can drive (as drives are wont to do) us to do extreme things when they are not met for long periods of time. While eating…
gregladen | January 26, 2011There are human universals. There, I said it. Now give me about a half hour to explain why this is both correct and a Falsehood. But first, some background and definition.
Most simply defined, a human universal is a trait, behavior or cultural feature that we find in all human societies. Men are always on average larger than women. All humans see the same exact range of colors because our eyes are the same. The range of emotions experienced by people is the same, and appears in facial expressions and other outward affect, in the same way across all humans.
The term "Human Universal"…
gregladen | October 22, 2010Human infants require more care than they should, if we form our expectations based on closely related species (apes, and more generally, Old World simian primates). It has been said that humans are born three months early. This is not accurate. It was thought that our body size predicted a 12 month gestation, and some suggested that Neanderthals would have had such, but this research conclusion has been set aside based on new analysis. But it is still true that developmentally, human children do not reach a stage of development that allows some degree of self care for a very long time…
gregladen | October 12, 2010This Friday's Skeptically Speaking will feature ...
... academic psychologist Dr. Cordelia Fine. Her new book, Delusions of Gender: How Our Minds, Society, and Neurosexism Create Difference, challenges the assumption that gender roles are wired into our brains, and shows us how ubiquitous cultural stereotypes are mistaken for actual fact.
That will be a life discussion with Desiree Schell.
Also, this Friday's edition of Skeptically Speaking will have the latest "Everything You Know is Sort of Wrong" in which Greg Laden (whoever the heck that is) asks if modern hobbies are an evolutionary…
