Although I can barely spell it, anthropomorphism this is one of my favorite words in the English language and one of the most fun writing faux pas one can make.
The writers of the APA Manual abhor it for grammatical reasons, as do most editors for vanity’s sake. For some reason, I know many an editor who has serious problems with catching this error. My guess is that it can be sneaky and often slip under the radar of even the most diligent editor.
Merriam-Webster defines it as an interpretation of what is not human or personal in terms of human or personal characteristics : Humanization.
For example, when an author writes, “The library was asked to allow three additional members to join the book club, despite the fact that it was already full,” the author is attributing human abilities (i.e., to listen or to be asked) to the library.
To fix this type of error, simply add the human element as such, “The library staff were asked to allow three additional members to join the book club, despite the fact that it was already full.”
