Not only must academics publish research to remain relevant, but doing so is a requirement—a key performance indicator—at many universities. Publishing rates can be used to determine an academic's value at an institution, and they can play a role in determining who will be granted tenure. https://www.scribendi.com/academy/articles/publish_or_perish.en.html
Academic journals make a point of ensuring that all submitted research is rigorously reviewed by experts in the field. This process is time consuming but ensures that false information is not distributed. The publish-or-perish system, then, helps promote accuracy in academia by requiring researchers to submit to high-quality, peer-reviewed journals. https://www.scribendi.com/academy/articles/publish_or_perish.en.html
The publish-or-perish system holds academics accountable to the public, ensuring that academics meet their goals and do research that will contribute to their fields of study. Thus, many view publishing as a moral requirement. Since the public funds public universities, the research they produce should be accessible to the public https://www.scribendi.com/academy/articles/publish_or_perish.en.html
