Sixty years ago the philosopher Jean-Paul Sartre wrote 'hell is other people'. Now, new evidence shows us that he was utterly wrong. Beginning from the first moments of life and at every age and stage, close contact with other people - and especially with women - affects how we think, whom we trust, and where we invest our money. Our social ties powerfully influence our sense of life satisfaction, our cognitive skills, and how resistant we are to infections and chronic disease. While information about diet, exercise, and new classes of drugs were the life-changing breakthroughs of the past decades, the new evidence is that social bonds - the people we know and care about - are just as critical to our survival. The Village Effect tells the story of the ways face-to-face human contact changes our minds, literally. Drawing on the latest discoveries in social cognition, social networks and neuroscience, salted with profiles of real people and their relationships, Susan Pinker explains why we are driven to trust other people and form lifelong bonds, and why we ignore these connections at our peril.
