This book received in September 2017 the most prestigious award for non-fiction literature of the Royal Society of London (the award is also called the "scientific Booker "). Many people are still confident that the differences between the sexes are so great that all men from Mars, and women certainly from Venus. And these differences between the sexes formed during evolution. Women are more cautious, and everything in them is subordinated to the idea of ​ ​ procreation, while men are leaders who try to be the first in everything. And each new generation only widens this gap between men and women. But is it really so? In her book, the famous neuropsychologist Cordelia Fine wittily analyzes all the prevailing ideas about the difference between the sexes. This dynamic book, at the same time entertaining and attractive for real erudites, is built on the basis of the latest ideas of science about evolution, psychology, neuroscience, endocrinology and philosophy. With the help of stories from everyday life, scientific data and common sense, the author breaks through the heap of stereotypes and ridiculous myths that this poignant topic has overgrown.
