第58章　心と先入観

Modern psychology is the science of the human mind. Among its top priorities is understanding how, day after day, ordinary people quietly form opinions about everything from a new neighbor to a foreign country.

One of the hardest problems it studies is the stereotype: a fixed image of a group of people that the mind quickly produces and reluctantly gives up. Such images can be useful shortcuts, but they often hide far more than they reveal. A patient in therapy may slowly discover that her sharpest judgments about others are little more than such stereotypes, picked up from a parent or a neighbor in childhood. Recognizing this is often the first step toward genuine change. Brain research suggests that each hemisphere of our brain handles experience slightly differently, just as the science of astronomy reveals the strange motions of distant stars. The picture is more sophisticated than the popular books suggest. Sometimes we must compromise between what we feel and what we know. We may suppose ourselves to be entirely open-minded, yet our reactions to a new face can be definitely instant and not always kind.

To overcome this bias, psychologists prompt us to relate our reactions to specific evidence, to render our quick judgments visible to ourselves, and somehow to leap beyond the comfortable image we hold of our own character.

Even a person who looks indifferent on the outside often carries a rich internal life — a private profile of memories, hopes, and quiet fears that no one else fully sees. Judging a stranger by a single glance can therefore be deeply unfair. Becoming truly fair requires a keen eye for our own mistakes, and a refusal to remain dull about the inner worlds of strangers. The most thoughtful adults learn to suspend judgment until they have actually listened.
