Final answer:
An increase in the effectiveness of initial commitment is often achieved when individuals are required to engage in efforts that lead them to value their actions or group membership more, as demonstrated by the foot-in-the-door technique and the justification of effort principle.
Step-by-step explanation:
The concept in question relates to the effectiveness of initial commitment and can be understood within the framework of social psychology. A factor that increases the effectiveness of an initial commitment is the requirement for the target to engage in an action that requires some effort. This principle is illustrated by the foot-in-the-door technique where an individual is persuaded to agree to a small request, which then leads to agreeing to a larger one. A hard initiation to a group can also make members value their membership more, as evidenced by the concept of justification of effort.
Furthermore, public actions that require significant commitment can influence the attitudes, ideas, and behaviors of others. This is harnessed in community-based projects that thrive on stakeholder commitment, and individual initiative plays a crucial role here. Those who take the initiative in such activities may sometimes feel guilt if success is not achieved or if boundaries are overstepped, but the effort put into such undertakings is often justified by the value we place on something we have worked hard to achieve.
