Prisoner's dilemma - is a two-person scenario in which (1) Player A stands to benefit more from a transaction by acting selfishly toward Player B if B offers to collaborate, and vice versa; but, (2) A and B together might obtain a bigger total payoff by collaborating than by acting selfishly in both cases. The typical result of a Prisoner's Dilemma is that both players act selfishly, which results to a poor decision for both.
With this system, one may strike a balance between rivalry and competitive for the benefit of all parties.
According to game theory, a situation where two players act selfishly would ultimately lead to a poor decision or getting smaller rewards for both is known as a prisoner's dilemma. The prisoner's dilemma also demonstrates the fact that sometimes, collaboration is not the best course of action.

Explanation:
While technology, population, environment factors, and racial inequality can prompt social change, only when members of a society organize into social movements does true social change occur. The phrase social movements refers to collective activities designed to bring about or resist primary changes in an existing society or group.
Wherever they occur, social movements can dramatically shape the direction of society. When individuals and groups of people—civil rights activists and other visionaries, for instance—transcend traditional bounds, they may bring about major shifts in social policy and structures. Even when they prove initially unsuccessful, social movements do affect public opinion.

Social scientists interest themselves in why social movements emerge. Do feelings of discontent, desires for a “change of pace,” or even yearnings for “change for the sake of change” cause these shifts? Sociologists use two theories to explain why people mobilize for change: relative deprivation and resource mobilization.
