I'm the ideal test reader for Brain Storm. I've always had reservations about the sweeping claims that there are fundamental differences in the organization of male and female brains, caused by prenatal hormones. But the sheer number of published studies that seemed to give incontrovertible evidence led me to assume that the theory was sound. This elegantly written and fascinating book has changed my mind. Jordan-Young's comprehensive analysis of the array of conflicting results and methodological weaknesses shows that we have closed the book on this topic far too soon. Her warning is one that all scientists can agree with: Careful!
This important and intellectually powerful book shows that a dominant paradigm in human sex differences is held together by chewing gum. By painstakingly examining a large and contradictory literature, Jordan-Young shows the weakness of the brain organization hypothesis. She has so much respect for the scientific method that she can hope that reason and integrity will help create a better, more empirically sound theory of sex differences, and she reaches out to scientists to offer a glimpse of a new psychobiology.
This is a book of remarkable depth that sets a new standard for clear scientific thinking about complex behavioral traits, as well as for interdisciplinary scholarship. Rebecca Jordan-Young charts a fresh new course through the morass of questions about gender and sexuality with enviable humor, fairness, and intellectual power.
Brain Storm poses the most comprehensive challenge yet to the claim that prenatal hormone exposure permanently structures the brain to be either masculine or feminine, and does so in a highly engaging, fair-minded narrative that is a delight to read.
Jordan-Young has written a stunning book that demolishes most of the science associated with the dominant paradigm of the development of sex and gender identity, behavior, and orientation. The current paradigm, brain organization theory, proposes: "Because of early exposure to different sex hormones, males and females have different brains"; and these hormones also create "gay" and "straight" brains. Jordan-Young interviewed virtually every major researcher in the field and reviewed hundreds of published scientific papers. Her conclusion: "Brain organization theory is little more than an elaboration of longstanding folk tales about antagonistic male and female essences and how they connect to antagonistic male and female natures." She explains, in exquisite detail, the flaws in the underlying science, from experimental designs that make no statistical sense to "conceptually sloppy" definitions of male and female sexuality, contradictory results, and the social construction of normality. Her conclusion that the patterns we see are far more complicated than previously believed and due to a wider range of variables will shake up the research community and alter public perception.
What Jordan-Young's analysis uncovered is by turns fascinating and appalling...This book is not only a tonic, it's also full of scientific insights presented in plain, intelligent prose--an absorbing read, if you've ever wondered what was going on in the secret parts of your attic.
It was with appreciation verging on glee that I read Barnard professor Rebecca Jordan-Young's devastatingly smart and definitive critique: Brain Storm: The Flaws in the Science of Sex Differences. Jordan-Young argues that the science of prenatal hormones, gender, and the mind "better resembles a hodgepodge pile than a solid structure." And she knows of what she speaks. An expert on measures and study designs, Jordan-Young has spent the last 13 years combing the literature on brain organization, unpacking assumptions, questioning methods and statistical practices, holding one paper up against another. She stresses that fetal hormones must matter to the brain--somehow. But after picking apart more than 400 studies that try to understand the genesis of particular psychological sex differences (real or supposed), she concludes that fetal T looks like an awfully anemic explanation...After decades of determined research, if robust links between prenatal hormones and "male" or "female" minds really exist, shouldn't we see those links across lots of different kinds of studies? This matters because the obsession with prenatal T can easily become a distraction. It can make us forget how much gender norms have changed--think of all those female accountants, lawyers, and doctors who weren't around 50 or even 30 years ago--and how remarkably similar men's and women's brains and minds actually are. All this unwarranted hammering away at difference (and its putative explanations) causes real trouble, too. As a growing body of research shows, cues that foreground gender and bring stereotypes to mind can dampen men's performance on tests of social sensitivity, women's scores on math tests, and women's stated interest in quantitative pursuits. Jordan-Young has done an enormous amount of work to untangle the gender claims. We ought to read her, cite her, thank her. And then, let's move on.
Jordan-Young ferret[s] out exaggerated, unreplicated claims and other silliness regarding research on sex differences. The book [is] strongest in exposing research conclusions that are closer to fiction than science.
Exhaustively analyses every relevant study on hormonal sex differentiation of the human brain, and argues that they are riddled with weaknesses, inconsistencies and ambiguity. It's a clarion call for better science on the subject.
In her exhaustive survey of the literature, Jordan-Young discovers a hodge-podge of tiny samples, inadequate controls, conflicting data and extravagant conclusions...By meticulously revealing the flawed research behind brain organization theory, she opens the way to a non-hierarchical study of sex difference that will be both more fruitful for science and less damaging for society.

Further, Victor Pride has written the most important 25 pages ever printed into an ebook. Women crave the book because Victor explains to men why they must cut out porn and masturbation. Hint: Both lower testosterone. That means he's less of a man. But remember, this book is for men only.
Both great men are like the father figure that most males on earth today never had. Further, they are completely authentic, sincere and they've an obsession with doing what brings positive changes in the course of world events.
One last thing, show Victor Pride some love. He feels loved, but he doesn't ask his readers to join him on social networks. However, you know a lot of males that are introverted or lack a certain confidence about them. Have them learn from Victor Pride. It's the best gift you can give any man, and it's free.
His work built my body strong, prepped me for the show. The injuries halted production of the show. But, the strength built because of his book Body of A Spartan was a big help when the hit and run accident caused the bleeds in my brain which caused multiple strokes. I learned to walk and talk again in record time. Sure, there's a long road ahead, but it's friends like Victor Pride and Mike Walsh that have been the examples and encouraged me every step.
Well. I did not finish this. I was looking for something based on science that could provide me with research studies and statistics, maybe some diagrams and charts. I wanted something that had actual content. What I got was a lot of opinion and stereotypes. I am very interested in learning about the differences in the female and male brain (like how the hippocampus is larger in the female brain and the amygdala is larger in the male brain) and how this affects us. But I also want the source material to be credible and, what's more, actually credited within the book. Brizendine would state things about the brain but there was no citation. She used examples of women and girls she knew. It all seemed a little too casual, almost made up. (Not that I want to be smacked in the face with a bunch of medical jargon.) There was only about one study mentioned in the one and a half chapters I read and, of course, the study wasn't cited (come on, footnotes aren't that hard). Her stereotypes of women are very...(I hate using this phrase) close-minded. There also didn't seem to be any sort of study that involved girls/women who weren't white. Then again, I didn't finish the book, so there might have been. But honestly, I doubt it.
Time to look for a different book instead. One that actually has some semblance of fact to it. Also, she straight up name dropped all her universities of study and residency on the first page. Calm down, miss. We know you've got your doctorate.
New research on the neural connections within the human brain suggests sex-based differences that many have suspected for centuries: women seem to be wired more for socialization and memory while men appear geared toward perception and coordinated action. The female brain appears to have increased connection between neurons in the right and left hemispheres of the brain, and males seem to have increased neural communication within hemispheres from frontal to rear portions of the organ. University of Pennsylvania researchers announced the results, generated by scanning the brains of about 1,000 people using a technique called diffusion tensor imaging, on Monday (December 2) in the PNAS.
