This came across as a little too disorganized and scattershot; a lot of this book reads like just a firehose of anecdotes, and there are a several not-very-well-related substantive topics that Grandin addresses. A bit more focus would make this a better book -- or even, a couple better books.

First, Grandin isn't talking about all visual thinking: she describes the distinction between spatial visualizers and object visualizers. The former is related more to abstract visualization and better-connected to verbal thinking; object visualizers, on the other hand, are, well, much more purely visual: they really, truly do see vivid, realistic images. And yes, Grandin is that latter type -- I mean, she did write a book called "Thinking in Pictures: My Life with Autism"! This book is focused on those object visualizers and their place in society; Grandin calls these the "clever engineers". I think she has a great point, that these people are dramatically undervalued these days, and that our education system, employment systems, and culture in general simply do not give these hands-on folks their due.

But then this book proceeds onto other topics. There's a section on disasters -- very reminiscent of Meltdown: Why Our Systems Fail and What We Can Do About It, Normal Accidents: Living with High-Risk Technologies, and even perhaps The Black Swan: The Impact of the Highly Improbable. And while Grandin has a good argument that visual thinking, and object visualizers in particular, are very helpful in avoiding disasters, accidents, and the general dangers of complex systems, I don't think there's anything so special to this, and that the benefit is not so specific to visual thinking, but rather, as Clearfield says in "Meltdown", the real benefit in avoiding meltdowns of various kinds comes from diversity of perspectives and experiences. This part of Grandin's book is interesting, but not very compelling.

So too is her section on genius and visual thinking. Yes, I'm sure many geniuses over history have been amazing visual thinkers. But I'm equally certain many geniuses have been spatial visualizers, or very verbally-focused. This section, too, feels like something she just tossed into the book.

A latter section on animal thinking is a bit more interesting, since that gets more at the specifics of visual thinking. Take bees, for example. They find food, fly back to the nest, do their dances, and communicate where the food is. This, and many other animal behaviors and cognition, do seem to be strong forms of visual thinking. Grandin, in this part of the book, makes a couple overtures towards an argument that visual thinking can be considered superior to verbal thinking, and I wish she would write that book: one tightly focused on human object visualizing, animal cognition as a form of visual thinking, the spectrum of the two, and why such thinking is unique and valuable.

This last part would mesh especially well with the flurry, in recent years, of work on cephalopod cognition; as well as insect cognition. This theoretical book would address the fact that our culture and society are very, very verbal and language-focused -- here, Grandin could start from The Master and His Emissary: The Divided Brain and the Making of the Western World, and address some of the left-brain, right-brain dichotomies. (A very literal dichtomy -- a division into two -- in the context of people who have their corpus callosum severed!)

This topic might also address AI, which has blown up so quickly here in early 2023: I mean, it's right there on the tin! ChatGPT and its ilk are large language models! One could describe the limitations of verbal thinking by drawing a throughline from ChatGPT back to the original Eliza chatbot. It does seem to be pretty simple to fool humans, using verbal thinking. Consider one of, the oh-so-convincing hallucinations of these large language model chatbots.

I myself am on the autistic spectrum, and share some of Grandin's object visualization tendencies (although I am obviously very much a spatial visualizer). I like Grandin's attitudes towards neurodiversity. But she has a couple great books, or perhaps long-form essays/pamphlets, buried in this book.
