Disclosure as I feel it's relevant: I am formally diagnosed with ASD and ADHD, and my kids have a soup of diagnoses. Further disclosure: Turns out I've read many of the books she cites.
This is a mess of a book on every level. By page 25, I'm pretty sure I was hate reading. I'm trying to distill down the central problem with the book, and I've landed on this: Nerenberg is not qualified to write it, and she packed so much into such a short book that she doesn't do a very good job of it.
I won't deride a journalist rather than a psychologist writing this book. The problem is really that Nerenberg is a recently self-diagnosed neurodivergent person (no specific diagnosis) and she makes some pretty basic errors like continuing to refer to Asperger's syndrome when it was removed from the DSM in 2013 for extremely good reasons. She has some anti-psychology tendencies that can result in throwing the baby out with the bathwater. To compound that problem, she is really bad at looking outside her own experience as someone who is low support needs and privileged. Everyone she interviews falls into that lane. It's an incredibly narrow lens. There's exactly one mention of race and class.
The history of psychology and psychiatry is undoubtedly beyond problematic, particularly in regards to women, and I can speak from personal experience. The models for ASD and ADHD in particular are heavily biased towards men. However, she gets somewhat dismissive towards diagnosis, period, and has an attitude towards the idea of "deficit" or "disorder" that is well meant but backwards. She believes that labeling things with negative terms creates stigma—a kind of Sapir-Worf hypothesis. My experience is more complex. Many ND people do have complex feelings about it, and perceive it, at least in part, as an abnormality. More importantly, the stigma precedes the label. Stigma is the cause, not the effect. I knew I was different and that my differences were not okay well before anyone put a label on it. Calling it a "disorder" didn't bother me, because I knew other people didn't think I was normal. Changing language is window-dressing.
The heart of her hypothesis seems to be that the core of neurodivergence in women is being highly sensitive, whether emotional or sensory. This assumption is poorly explored and much more problematic than she thinks. Instead of merely correcting narratives about lack of empathy or theory of mind, it sets up a form of gender essentialism. It doesn't describe all women, and it also sets a false dichotomy over sensitivity. I don't know if she simply thinks that women who meet a more traditional profile would already have a diagnosis or what. But if we don't fit that "highly sensitive" profile, we don't fit her vision of neurodivergence.
The first section covers several diagnoses or quasi-diagnoses. The first is the most problematic: Highly Sensitive Person. The concept of high-sensitivity is valid. The problem is that even Elaine Aron says it's not a disgnosis, merely a neutral trait. When you dig in, the way HSP has been used is not great. Many autism advocates feel that it's anti-autistic, as it uses many autistic traits but only ones considered positive, and Dr. Aron has said negative things about autistic people. Because of the ways sensory and emotional sensitivity are blended, the description of "highly sensitive" feels vague and the questionnaire doesn't read well. ("I have a rich, complex inner life.")
The sections on autism and ADHD are, again, brief and the people interviewed fall into a narrow slice. It's all high achieving, highly educated women. If you even had trouble in college due to neurodivergence? Not for you. The SPD section is another story. There is a reason SPD continues to be rejected by the DSM committee, and it's not that they don't think sensory issues don't exist—they're in the diagnostic criteria for ASD. They're not convinced that SPD is a standalone diagnosis, rather than a symptom cluster that's associated with other diagnoses. Pretty much the whole chapter is about the STAR institute, which I will note ran Google ads when my kids were little, saying maybe it's not autism, it's SPD, visit spdstar dot org.
The 3rd part is "what's next?" and it mostly suffers from incoherence. There's bits of interviews with people (I noticed she never quotes anyone who pushes back or offers nuance). There's bits of ideas about work, home, relationships, therapy. She relies on anecdote over evidence. (Yes, sensory rooms look cool. Yes, some people benefit from them, based on self-reporting. There is no solid data.) She briefly touches on how autistic women can go undiagnosed because they don't fit stereotypes, but she doesn't even consider the problem of how we may be creating new stereotypes of female-coded autism.
I'm sure some people will see themselves in this book, but it excludes too many people, and the sloppy research is really inexcusable. It comes off as someone who discovered the concept of neurodivetsity and that it might apply to her—and then instead of taking time to really learn and work with people who were already in the space, she went and wrote a book and launched her own project.
