Definition of gatekeeper

The term "gatekeeper" originated in the early 20th century in the context of security and access control. A gatekeeper was a literal person who controlled access to a property or a gate, such as a castle or a large estate. They would decide who was allowed to enter or exit, often based on pre-established criteria such as identity, authority, or permission. The term later expanded to metaphorical contexts, such as social hierarchies, where a "gatekeeper" refers to someone who has the power to decide who can enter or participate in a particular group, community, or social circle. In modern times, the term is often used in digital contexts, such as online platforms, where a "gatekeeper" is a person or entity that controls access to certain information, resources, or networks. Overall, the concept of a gatekeeper implies a person or entity that has the authority to control the flow of people, information, or resources.
