Emotional Intelligence was an international phenomenon, appearing on the "New York Times" bestseller list for over a year and selling more than 5 million copies worldwide. Now, once again, Daniel Goleman has written a groundbreaking synthesis of the latest findings in biology and brain science, revealing that we are `wired to connect` and the surprisingly deep impact of our relationships on every aspect our lives. Far more than we are consciously aware, our daily encounters with parents, spouses, bosses, and even strangers, shape our brains and affect cells throughout our bodies, down to the level of our genes - for good or ill. In "Social Intelligence", Daniel Goleman explores an emerging new science with startling implications for our interpersonal world. Its most fundamental discovery: we are designed for sociability, constantly engaged in a `neural ballet` that connects us brain-to-brain with those around us. Goleman explains the surprising accuracy of first impressions, the basis of charisma and emotional power, the complexity of sexual attraction, and how we detect lies. He describes the `dark side` of social intelligence, from narcissism to Machiavellianism and psychopathy. He also reveals our astonishing capacity for `mindsight`, as well as the tragedy of those, like autistic children, whose mindsight is impaired. In this book Daniel Goleman delivers his most heartening news with powerful conviction: we humans have a built-in bias toward empathy, cooperation and altruism - provided we develop the social intelligence to nurture these capacities in ourselves and others.
