Articles and posts on the Friendly Specter blog are researched from trusted sources, such as literature and writings from well-known authors in the paranormal field. If I used reference books and guides, you would find links to the source at the end of the article or as direct links. Some of the links are affiliate links to Amazon.
I use source criticism and make the articles balanced by adding different viewpoints. As the paranormal field is a minefield of misinformation I take great pride in trying to give a broad perspective in my articles.
As a paranormal investigator and ghost enthusiast, I add personal experiences and knowledge gathered in my line of work to add value to the content.
