Invisible Women: Data Bias in a World Designed for Men by Caroline Criado Perez (Non-fiction)

A fascinating (but somewhat uneven) book that looks at the way the needs of half of the world’s population (women) are ignored in the design of almost every system and object on the planet. From transportation systems, to medicine, to the sizes of tools, cars, and piano keyboards, Perez points out the insidious way that women’s needs aren’t considered unless they perfectly align with men’s. She divides the book into three themes: the female body, women’s unpaid care burden, and male violence against women. It’s a mixed bag — a huge pile of information (with references) — some of which is deeply insightful, some politically motivated, and some really about the needs of groups which may be predominantly women but are not necessarily problems of women because they are women.

The best parts (for me) focused on the (ignored) biological differences in the female body. Examples include different heart attack signs, incorrect medication dosages, and pacemaker thresholds. What amazed me was that some studies have shown different medication efficacy at different stages of the menstrual cycle — and yet no pharmaceutical trials ever even consider that. Why? As one researcher said — it’s just too hard! Other aspects of the “female body” theme are a little less cut and dried. Many, many, things from tools, to voice recognition systems, to pianos, to car seats, to the temperature in offices are designed for “the average man.” I always have trouble with averages because that means that many men — who are not average size — will also have trouble with these things depending on the shape of the curve and the spread in sizes. Still — I found all of these stories to be fascinating and primarily things I had never considered. I had some issues with the other two themes — the assumptions and calculations didn’t always make sense to me — though they did give me something to think about.

Overall this is a really fascinating collection of data (or lack of data) about how the world that we live in considers women to be the “exception to the norm.” While I found that some of the examples strain the point — really belonging to other groups, many of whom happen to be women; calculations of economic productivity that leave out factors not supporting her conclusion; items based on averages that are not working for non-average men as well as women, etc — there are an equal number of truly fascinating studies and examples that completely shifted the way I thought about things.

Recommended, but keep your own thinking cap on before blindly accepting all of her conclusions….
