Definitely. Norman Bates is purely fictional. He was created by authors and has appeared in books, movies, and other forms of entertainment to thrill and scare audiences.
In most cases, Norman is not based on a true story. It's more likely a creation of the writer's mind to entertain and engage the audience with an interesting fictional narrative.
Well, without more context, it's difficult to say exactly who James Burton in science fiction is. He could be a new emerging talent in the field. For example, he might be a concept artist who is creating amazing visuals for science - fiction video games or movies that are still in development. Or perhaps he is a scientist who has written some speculative science - fiction based on his research.
