Libraries are a binary world of fiction and non-fiction. But the real world is not so black and white. It is not always clear, sometimes the edges are blurred.
The increasing popularity of misinformation in pop culture and mainstream media may mean we need to rethink how information is labeled. Misinformation is sitting on our library shelves, undermining our efforts at bringing people the truth. For example, if a library user Ancient Alien theory in the non-fiction section of the library, they might assume it is valid information. Ancient Aliens might seem harmless, but its thinly veiled racism is culturally harmful. It also promotes the idea that experts should not be listened to and does not present both views. While libraries support questioning experts, the also promote sharing unbiased information and critical thinking.
This same scenario could easily apply to homeopathic healing information. A user might not seek medical help from a doctor if they find an untested cure for a serious issue. And do not get me started on political opinions paraded as truth and fact. If we adjust labeling to reflect the content it could help library users to make more informed choices.
I realize this is a censorship issue and does some critical thinking work for our customers, but I believe it will be helpful in helping users identify better information sources. Our minds want to organize and categorize things. If we label some materials as opinion or pseudoscience, library users will be able to connect those concepts and labels with what they really are. This allows for a shared concept of truth.
Just because something has always been done a certain way, does not always mean it is the best way.
