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.
