When the influencer enlists other people to help influence the target, what is this approach called?

The correct answer is coalitions. In the context of influence and persuasion, coalitions refer to a strategy where an influencer gathers support from others to strengthen their position and impact their target more effectively. This approach leverages the idea that a united front can be more persuasive than an individual voice, as it combines various perspectives and resources to present a more compelling argument.

By building a coalition, the influencer can create a sense of solidarity among supporters, making it more challenging for the target to dismiss the request or message. The collective effort often enhances credibility and signals to the target that a broader consensus exists, which can further motivate them to comply or align with the desired outcome.

Other options like collaboration and exchange pertain to different dynamics in influence. Collaboration suggests working together towards a common goal, which may not specifically imply enlisting others for persuasion. Exchange involves a give-and-take scenario, where benefits are traded, rather than a coalition being formed for influence purposes. Pressure, on the other hand, typically involves more coercive tactics, which contrast with the supportive nature of coalitions.
