non-excludability
Non-excludability refers to a situation where it is difficult or impossible to prevent people from accessing a resource or service. In the context of general knowledge, once information is available—like facts, ideas, or cultural content—it becomes accessible to everyone. For example, once scientific research is published online, anyone can read it without restrictions. This characteristic often leads to benefits for society, as knowledge can be shared widely, but it can complicate ownership and funding, as individuals cannot easily charge others for access to that knowledge.

Non-excludability is a characteristic of certain goods or resources that means once they are provided, it's difficult or impossible to prevent anyone from using them. For example, public goods like clean air or national defense benefit everyone, regardless of whether they contribute to their provision. This can lead to challenges, as individuals might rely on others to provide these goods, which can result in underfunding or depletion over time. Essentially, non-excludability highlights the importance of collective responsibility in maintaining resources that are beneficial to all.
