Invisible Women by Caroline Criado Perez – a world designed for men

From the 'one-size-fits-men' approach to smartphone design to the medical trials that are putting women's lives at risk " this book uses data like a laser

The problem with feminism is that it's just too familiar. The attention of a jaded public and neophiliac media may have been aroused by #MeToo, with its connotations of youth, sex and celebrity, but for the most part it has drifted recently towards other forms of prejudice, such as transphobia. Unfortunately for women, though, the hoary old problems of discrimination, violence and unpaid labour are still very much with us. We mistake our fatigue about feminism for the exhaustion of patriarchy. A recent large survey revealed that more than two thirds of men in Britain believe that women now enjoy equal opportunities. When the writer and activist Caroline Criado Perez campaigned to have a female historical figure on the back of sterling banknotes, one man responded: "But women are everywhere now!"

It's a smart strategy, therefore, to invite readers to view this timeworn topic through the revealing lens of data, bringing to light the hidden places where inequality still resides. Criado Perez has assembled a cornucopia of statistics - from how blind auditions have increased the proportion of female players hired by orchestras to nearly 50%, to the good reasons why women take up to 2.3 times as long as men to use the toilet. This is a man's world, we learn, because those who built it didn't take gender differences into account. Most offices, we learn, are five degrees too cold for women, because the formula to determine their temperature was developed in the 1960s based on the metabolic resting rate of a 40-year-old, 70kg man; women's metabolisms are slower. Women in Britain are 50% more likely to be misdiagnosed following a heart attack: heart failure trials generally use male participants. Cars are designed around the body of "Reference Man", so although men are more likely to crash, women involved in collisions are nearly 50% more likely to be seriously hurt.
