    That's taught as fact in psychology textbooks, academic journals, and bestselling books. And these hardwired differences explain everything from sexual orientation to gender identity, to why there aren't more women physicists or more stay-at-home dads.In this compelling book, Rebecca Jordan-Young takes on the evidence that sex differences are hardwired into the brain. Analyzing virtually all published research that supports the claims of "human brain organization theory," Jordan-Young reveals how often these studies fail the standards of science. Even if careful researchers point out the limits of their own studies, other researchers and journalists can easily ignore them because brain organization theory just sounds so right. But if a series of methodological weaknesses, questionable assumptions, inconsistent definitions, and enormous gaps between ambiguous findings and grand conclusions have accumulated through the years, then science isn't scientific at all.Elegantly written, this book argues passionately that the analysis of gender differences deserves far more rigorous, biologically sophisticated science. "The evidence for hormonal sex differentiation of the human brain better resembles a hodge-podge pile than a solid structure... Once we have cleared the rubble, we can begin to build newer, more scientific stories about human development."

    These three Great Untruths are part of a larger philosophy that sees young people as fragile creatures who must be protected and supervised by adults. But despite the good intentions of the adults who impart them, the Great Untruths are harming kids by teaching them the opposite of ancient wisdom and the opposite of modern psychological findings on grit, growth, and antifragility. The result is rising rates of depression and anxiety, along with endless stories of college campuses torn apart by moralistic divisions and mutual recriminations. This is a book about how we got here. First Amendment expert Greg Lukianoff and social psychologist Jonathan Haidt take us on a tour of the social trends stretching back to the 1980s that have produced the confusion and conflict on campus today, including the loss of unsupervised play time and the birth of social media, all during a time of rising political polarization. This is a book about how to fix the mess. The culture of “safety” and its intolerance of opposing viewpoints has left many young people anxious and unprepared for adult life, with devastating consequences for them, for their parents, for the companies that will soon hire them, and for a democracy that is already pushed to the brink of violence over its growing political divisions. Lukianoff and Haidt offer a comprehensive set of reforms that will strengthen young people and institutions, allowing us all to reap the benefits of diversity, including viewpoint diversity. This is a book for anyone who is confused by what’s happening on college campuses today, or has children, or is concerned about the growing inability of Americans to live and work and cooperate across party lines.

    My name is Hida Viloria. I was raised as a girl but discovered at a young age that my body looked different. Having endured an often turbulent home life as a kid, there were many times when I felt scared and alone, especially given my attraction to girls. But unlike most people in the first world who are born intersex--meaning they have genitals, reproductive organs, hormones, and/or chromosomal patterns that do not fit standard definitions of male or female--I grew up in the body I was born with because my parents did not have my sex characteristics surgically altered at birth. It wasn't until I was twenty-six and encountered the term intersex in a San Francisco newspaper that I finally had a name for my difference. That's when I began to explore what it means to live in the space between genders--to be both and neither. I tried living as a feminine woman, an androgynous person, and even for a brief period of time as a man. Good friends would not recognize me, and gay men would hit on me. My gender fluidity was exciting, and in many ways freeing--but it could also be isolating. I had to know if there were other intersex people like me, but when I finally found an intersex community to connect with I was shocked, and then deeply upset, to learn that most of the people I met had been scarred, both physically and psychologically, by infant surgeries and hormone treatments meant to "correct" their bodies. Realizing that the invisibility of intersex people in society facilitated these practices, I made it my mission to bring an end to it--and became one of the first people to voluntarily come out as intersex at a national and then international level.Born Both is the story of my lifelong journey toward finding love and embracing my authentic identity in a world that insists on categorizing people into either/or, and of my decades-long fight for human rights and equality for intersex people everywhere.

    In pursuing this mystery, Elisabeth Lloyd arrives at another: How could anything as inadequate as the evolutionary explanations of the female orgasm have passed muster as science? A judicious and revealing look at all twenty evolutionary accounts of the trait of human female orgasm, Lloyd's book is at the same time a case study of how certain biases steer science astray.Over the past fifteen years, the effect of sexist or male-centered approaches to science has been hotly debated. Drawing especially on data from nonhuman primates and human sexology over eighty years, Lloyd shows what damage such bias does in the study of female orgasm. She also exposes a second pernicious form of bias that permeates the literature on female orgasms: a bias toward adaptationism. Here Lloyd's critique comes alive, demonstrating how most of the evolutionary accounts either are in conflict with, or lack, certain types of evidence necessary to make their cases--how they simply assume that female orgasm must exist because it helped females in the past reproduce. As she weighs the evidence, Lloyd takes on nearly everyone who has written on the subject: evolutionists, animal behaviorists, and feminists alike. Her clearly and cogently written book is at once a convincing case study of bias in science and a sweeping summary and analysis of what is known about the evolution of the intriguing trait of female orgasm.

    One of these "spirit people" delivered a message that would ultimately save her life. Still, she wanted nothing to do with these visitors and sought help from her local Spiritualist church. There she learned to embrace these new experiences, opening her to a lifetime of service that has spanned continents. World-renowned and universally respected and beloved as a medium and teacher for over fifty years, Mavis Pittilla remains modest and humble. The story of her life reveals a multi-faceted, endearing woman who has overcome tremendous adversity, much of it caused by her own human frailties. Droplets of God is far more than Mavis's fascinating biography. It is a primer of the foundations of mediumship, the key philosophical teachings of Spiritualism, and of the soul's journey of self-realization.

    The historical breadth of Boswell's research (from the Greeks to Aquinas) and the variety of sources consulted (legal, literary, theological, artistic, and scientific) make this one of the most extensive treatments of any single aspect of Western social history. The product of ten years of research and analysis of records in a dozen languages, this book opens up a new area of historical inquiry and helps elucidate the origins and operations of intolerance as a social force.

    Much more than the "facts of life" or “the birds and the bees," Sex Is a Funny Word opens up conversations between young people and their caregivers in a way that allows adults to convey their values and beliefs while providing information about boundaries, safety, and joy.The eagerly anticipated follow up to Lambda-nominated What Makes a Baby, from sex educator Cory Silverberg and artist Fiona Smyth, Sex Is a Funny Word reimagines "sex talk" for the twenty-first century.

    PoMo: short for PostModern; in the arts, a movement following after and in direct reaction to Modernism; culturally, an outlook that acknowledges diverse and complex points of view.PoMoSexual: the queer erotic reality beyond the boundaries of gender, separatism, and essentialist notions of sexual orientation.

    Whatever happened to sexual flamboyance and gender liberation, an end to marriage, the military, and the nuclear family? As backrooms are shut down to make way for wedding vows, and gay sexual culture morphs into “straight-acting dudes hangin’ out,” what are the possibilities for a defiant faggotry that challenges the assimilationist norms of a corporate-cozy lifestyle?Why Are Faggots So Afraid of Faggots? challenges not just the violence of straight homophobia but the hypocrisy of mainstream gay norms that say the only way to stay safe is to act straight: get married, join the military, adopt kids! Mattilda Bernstein Sycamore reinvokes the anger, flamboyance, and subversion once thriving in gay subcultures in order to create something dangerous and lovely: an exploration of the perils of assimilation; a call for accountability; a vision for change. A sassy and splintering emergency intervention!Called "startlingly bold and provocative" by Howard Zinn, and described as "a cross between Tinkerbell and a honky Malcolm X with a queer agenda" by The Austin Chronicle, Mattilda Bernstein Sycamore is undoubtedly one of America's most outspoken queer critics. She is the author of two novels, including, most recently, So Many Ways to Sleep Badly, and is the editor of four nonfiction anthologies, including Nobody Passes: Rejecting the Rules of Gender and Conformity and That’s Revolting! Queer Strategies for Resisting Assimilation.

    Yet underlying these subtle differences, Simon Baron-Cohen believes, there is one essential difference, and it affects everything we do: Men have a tendency to analyze and construct systems while women are inclined to empathize. With fresh evidence for these claims, Baron-Cohen explores how these sex differences arise more from biological than cultural causes and shows us how each brain type contributes in various ways to what we think of as "intelligence." Emphasizing that not all men have the typically "male" brain, which he calls Type "S," and not all women have the typically female brain (Type "E"), Baron-Cohen explores the cutting-edge research that illuminates our individual differences and explains why a truly "balanced" brain is so rare. Filled with surprising and illuminating case studies, many from Baron-Cohen's own clinical practice, The Essential Difference moves beyond the stereotypes to elucidate over twenty years of groundbreaking research. From gossip to aggression, Baron-Cohen dissects each brain type and even presents a new theory that autism (as well as its close relative, Asperger's syndrome) can be understood as an extreme form of the male brain. Smart and engaging, this is the thinking person's guide to gender difference, a book that promises to change the conversation about-and between-men and women.
