Obscurantism is a term used to describe an attitude or policy that seeks to keep information hidden, obscured or withheld from others. It often refers to attempts by those in positions of power to control access to knowledge and limit the spread of information, particularly when it challenges their authority or beliefs. Obscurantism can take many forms, including censorship, suppression of dissenting views, manipulation of facts, and outright lies. It is often associated with religious institutions, governments, or other powerful organizations that seek to maintain control over information in order to preserve their power or influence.
