This is a book that once again will be ignored by those who don't want to hear it. I'm sure it has added to the authors litany of threats but it's a book that needs to be read that needs to be thought about and examined. Yes there may be errors, but honestly I want to see your proof and if you're coming at this going "well actually the number is 77% not 78% and with that error how can we trust any of it" I don't want to hear it.
There were two things that stood out for me in this book, one was the Policewoman who had breast reduction surgery to make her stab vest safe... the other is that 78% of female pianists (47% of men) have hand pain and that if they just could use the 7/8 DS keyboard that this would be drastically reduced. The reason the second anecdote stood out for me is because I had ganglion surgery at 21 and stopped doing piano exams because the Octave scales were causing pain. I had done 7 of 8 exams before the Diploma. Barely passing the last one so I decided to cut my losses.
I'm a short woman, I wear a padded piece on the seatbelt of the car because otherwise it rubs painfully. I'm also aware that front impact protection bags can kill women my size. But the fact that we're in a world where it's acceptable to ignore 50% (I've seen the numbers at 51% but let's just go broad here) of the population because it's messy to properly do the research. Ignoring the fact that body chemistry can have impact on things. The fact that a lot of tools to help detect that a person has fallen over involves phones in pockets... when most women can't carry them that way.
Read this book, no really, there may be some errors in it but overall it's a book that designers and most men need to read and then ask themselves why women aren't angrier.
