"Gatekeeping is the control of access to information and resources, often by a select group of people or institutions."
Here's why:
* Control of access: Gatekeeping is fundamentally about who gets to see or use something.
* Information and resources: This encompasses a wide range of things, from news stories to job opportunities to academic journals.
* Select group: Gatekeepers are not always obvious, but they are always present. They can be editors, publishers, hiring managers, or even social media algorithms.
Other options might focus on specific aspects of gatekeeping, but this definition captures the core concept of restricted access.
