WHAT IT’S REALLY ABOUT
Biology, Sex Differences, And Misunderstood Instincts: Dr. Carole Hooven Unpacked
- Chris Williamson and evolutionary biologist Dr. Carole Hooven discuss biological sex differences, focusing on maternal instinct, testosterone, and how these shape male and female behavior. Hooven critiques cultural narratives claiming maternal instinct is a patriarchal myth, arguing they ignore extensive cross‑species and neurological evidence. They explore how testosterone organizes bodies and brains, influences libido, aggression, parenting, mood, and even orgasm quality, including insights from transgender individuals on hormone therapy. The conversation also covers sex as a binary, childhood sex differences, grip strength and mating success, and Hooven’s desire to write a science-based, sympathetic book on male puberty and masculinity.
IDEAS WORTH REMEMBERING
5 ideasMaternal instinct is biologically real and widely cross-species, even if its expression varies.
Hooven argues maternal care is deeply rooted in mammalian biology: in ~95% of mammals, females provide nearly all parental care, and we understand hormonal and neural mechanisms (e.g., oxytocin, dopamine) that support maternal motivation. Recognizing this does not mean women must mother in any prescribed way or surrender career ambitions.
Facts about nature and human rights should be kept separate.
Hooven insists we do not need to distort or deny biological reality (e.g., sex differences, maternal instinct) to argue for equal rights or opportunities. Descriptive claims about how males and females evolved are distinct from normative decisions about laws, roles, or moral rights.
Sex is binary in humans, even though traits linked to sex exist on spectra.
Despite variation in gender expression and rare intersex conditions, humans—like other mammals—have two sexes defined by gamete type (sperm vs. ova). Most so‑called “intersex” individuals are still clearly male or female; extremely rare cases with mixed gonadal tissue do not invalidate the overall two‑sex structure.
Testosterone coordinates physical capacity with motivation, not just ‘sex drive’ in isolation.
In males, testosterone shapes genital development, muscle mass, strength, risk-taking, competitiveness and sexual motivation, aligning body and behavior to maximize reproductive opportunities. In involved fathers, testosterone typically drops, facilitating nurturing behavior—showing hormone effects are context-sensitive, not monolithically ‘toxic’.
Trans men’s experiences on testosterone highlight how radically hormones can shift perception and desire.
Many females transitioning to male report a shocking surge in libido and more objectified sexual focus on body parts, along with newfound empathy for how powerful male sexual drive can feel. Some also describe changes in emotional range and orgasm quality, underscoring the hormonal underpinnings of sex differences.
WORDS WORTH SAVING
5 quotesOf course there’s a maternal instinct. We don’t need to twist the facts of biology to support anybody’s rights.
— Dr. Carole Hooven
What exists in nature is not the same thing as what people’s human rights are. We decide what kind of society we want.
— Dr. Carole Hooven
It blows my mind that people can be so ostensibly pro‑female and obviously anti‑mother.
— Chris Williamson
Evolution doesn’t give you weapons and sperm and then no desire to use it.
— Dr. Carole Hooven
Any woman could have been born male, so I don’t see why women get to be so judgy about what it’s like to be a man.
