As social psychologists, we study how the groups that people belong to become part of their sense of self—and how those identities fundamentally shape how they understand the world, what they feel and believe, and how they make decisions. . . .
Knowing yourself is about understanding how your identity is shaped and reshaped by the social world that you are inextricably embedded in—as well as how you shape the identities of people around you.
Understanding how identity works provides a special type of wisdom: the ability to see, make sense of, and (sometimes) resist the social forces that influence you. It also gives you the tools to influence the groups you belong to. Among other things, you can learn how to provide effective leadership, avoid groupthink, promote cooperation, and fight discrimination.

Assigning people to an arbitrary group can immediately affect patterns of brain activity, change how they look at others, and, at least momentarily, override racial biases. [Group studies have] fundamentally reshaped how we understand the nature of human identity. They have clarified to us that there is no true social vacuum. In many ways, the psychology of groups is the natural human condition.
-----
What people think, feel, and do is influenced, often to a startling degree, by what they believe everyone else is thinking, feeling, and doing. And because they are bound to groups and identities, the particular norms that guide people at any given moment can vary depending on which parts of themselves are the most salient and active.

Social motives and beliefs can outweigh the desire for accuracy, causing people to be overly credulous when it comes to identity-affirming information. We have conducted several studies in which we found that people tend to believe positive stories about their in-groups and negative stories about out-groups, no matter how dubious the information may be.
-----
Social identities provide potent incentives for cooperation. . . . people more readily cooperate and improve outcomes for everyone when they identify with their groups and adhere to cooperative social norms. This has critical implications for creating groups and organizations that function effectively.
-----
The point of examining bias, implicit and otherwise, is so we can understand that our minds sometimes produce behaviors and outcomes that are inconsistent with our broader beliefs and values. And recognizing this, we can take control, exerting agency to challenge ourselves and others to build a better world.
-----
How much we offer help to other people, like so much else, depends on whether we see them as sharing a part of our identities. The philosopher Peter Singer refers to this idea as a “moral circle,” the boundaries of which determine who is deserving of our concern—and, of course, who is not. . . .
The boundaries of our identities are not fixed; they can vary across time and situations based on what is most salient. . . . the people we feel a responsibility to help and care for in any given moment is fluid.
-----
Human beings’ most important social identities are created around and fostered by shared traditions, rituals, histories, myths and stories, memories of accomplishments, and joys. But they are also forged by adversity, hardship, and the ways people are treated and mistreated by others.
-----
What great leaders do, no matter their domain, is tell stories about identity. . . .
Iconic moments of leadership . . . are instances of embodiment. They are powerful because they capture an essence. But it is an essence not simply of the leaders themselves—their particular dynamism or brilliance or charisma—it is an essence of us, of the group as a whole. They are moments in which the actions of a leader exemplify something about who we are or perhaps who we aspire to be.
-----
People cooperate and coordinate with one another much more readily when they see themselves as sharing an identity. The identities we activate and act upon are often those that differentiate us from others, whether they be based on boundaries of occupation, religion, race, gender, or nation. But, as we have seen, people are also drawn together by common fate, when they recognize that they share the same set of circumstances and are ultimately subject to the same destiny.
