A "hollow promise" refers to a commitment or assurance that lacks sincerity or intention to follow through. It often leaves the recipient feeling misled or disappointed, as the promise is not backed by genuine effort or capability. This term is commonly used in various contexts, including personal relationships, business dealings, and political statements. In many cases, hollow promises can erode trust between individuals or groups. For instance, when a leader makes a political promise during a campaign but fails to deliver once in office, it can lead to disillusionment among voters. Ultimately, hollow promises can damage reputations and hinder future cooperation.
