I'd argue the target audience is the "layman" in a tangential field. So, they have enough background that what the article talks about doesn't go above their head, and they can get a quick overview of the subject, but it doesn't require them having to read up on a bunch of materials outside their field. Think people like mathematicians that work in tandem with physicists in their institutions, but don't read into it as much themselves.
