What type of power allows an individual to control access to important information?

The power that allows an individual to control access to important information is informational power. This type of power is derived from an individual's possession of valuable data or insights that others need or want. When someone has access to critical information, they can influence decisions, guide actions, and affect outcomes based on the sharing or withholding of that information.

In many organizational contexts, having this type of power can enhance a person's ability to lead, persuade, or manipulate situations to their advantage, as others may seek out that information to make informed decisions or to better understand the environment in which they operate. This can create a gatekeeping role where the individual can leverage their information control for various purposes, such as collaboration, negotiation, or asserting influence over processes and outcomes.

In contrast, legitimate power stems from a person's official position or authority, referent power is based on admiration or respect, and expert power arises from specialized knowledge or skills. While all these forms of power can influence others, informational power specifically highlights the ability to manage and regulate access to key information.
