• The form of the resources shapes the activities of the movement (e.g., access to a TV station will result in the extensive use TV media)

• Movements develop in contingent opportunity structures that influence their efforts to mobilize; as each movement's response to the opportunity structures depends on the movement's organization and resources, there is no clear pattern of movement development nor are specific movement techniques or methods universal

Critics of this theory argue that there is too much of an emphasis on resources, especially financial resources. Some movements are effective without an influx of money and are more dependent upon the movement members for time and labor (e.g., the civil rights movement in the USA).

Political Process Theory

Political process theory is similar to resource mobilization in many regards, but tends to emphasize a different component of social structure that is important for social movement development: political opportunities. Political process theory argues that there are three vital components for movement formation: insurgent consciousness, organizational strength, and political opportunities.

Insurgent consciousness refers back to the ideas of deprivation and grievances. The idea is that certain members of society feel like they are being mistreated or that somehow the system is unjust. The insurgent consciousness is the collective sense of injustice that movement members (or potential movement members) feel and serves as the motivation for movement organization.

Organizational strength falls in line with resource-mobilization theory, arguing that in order for a social movement to organize it must have strong leadership and sufficient resources.

Political opportunity refers to the receptivity or vulnerability of the existing political system to challenge. This vulnerability can be the result of any of the following (or a combination thereof):

• Growth of political pluralism

• Decline in effectiveness of repression

• Elite disunity; the leading factions are internally fragmented

• A broadening of access to institutional participation in political processes

• Support of organized opposition by elites

One of the advantages of the political process theory is that it addresses the issue of timing or emergence of social movements. Some groups may have the insurgent consciousness and resources to mobilize, but because political opportunities are closed, they will not have any success. The theory, then, argues that all three of these components are important.

Critics of the political process theory and resource-mobilization theory point out that neither theory discusses movement culture to any great degree. This has presented culture theorists an opportunity to expound on the importance of culture.

One advance on the political process theory is the political mediation model, which outlines the way in which the political context facing movement actors intersects with the strategic choices that movements make. An additional strength of this model is that it can look at the outcomes of social movements not only in terms of success or failure but also in terms of consequences (whether intentional or unintentional, positive or negative) and in terms of collective benefits.
