Accounts of manipulation typically focus on whether an agent’s preferences have been altered in problematic ways or whether external forces have interfered with their decision-making. This paper argues that such approaches fail to identify the structural feature that distinguishes manipulation from ordinary influence. The distinction lies not in whether an agent’s motivations are affected, but in how they are affected. Influence operates through the agent’s integrative processes, allowing motivations to be incorporated into a coherent structure. Manipulation, by contrast, operates by bypassing these processes, altering the role of motivations in action without making those alterations available for integration. On this account, agency is undermined not when outcomes are externally shaped, but when the mechanisms of integration are displaced. This reframing provides a unified structural criterion for distinguishing permissible influence from manipulative control.
