This shows several common problems that I've been cleaning up all day:
- People categorizing books in subcategories and their parent categories simultaneously.
- Mixing up subjects that are only peripherally related. The book in question was probably a sociology book or a psychology book, not both.
- Authors tend to get a little grandiose with their conceptions about a book. Just because a book deals with psychology, and a person's psychology is affected by their brains, that doesn't mean every psychology book is also a neuroscience book.
- "Cognition" really isn't a topic for a book, or is a very uncommon one if it is. People tend to treat a bunch of related-words as categories, and every book picks a different set of strange words to use. Categories are supposed to be a way to keep like books together, but that only works if books use a common set of subject names.
