High grades don't guarantee a good life
For decades, the intelligence quotient was treated almost like destiny: whoever scored high on logic and reasoning tests seemed destined for professional and personal success. Goleman gathers decades of research to show that this math doesn't add up on its own.
He describes brilliant students who stumble in precisely the most ordinary situations of adult life: arguments with a partner, conflict at work, decisions made under pressure. The problem wasn't a lack of technical intelligence, it was a lack of another kind of skill, just as real as the first.
An easy example to recognize: that brilliant coworker who solves any complicated technical problem alone, but blows up at the team over the smallest delay, hurting his own work in the end. Over time, the whole team starts avoiding bringing problems to him, even knowing he would solve them fast, just out of fear of the explosion.
Goleman doesn't dismiss the importance of logical reasoning. He just argues that this other skill, historically ignored in schools and companies, weighs just as much, and in some situations even more, in determining how someone really does in life.
