Right, but a professor specifically is someone who in most instances can at best be said to have once done some research before graduating into managing researchers (grad students). It's like saying "programmers don't behave like _____, based on my experience with mid-level managers in technical organizations."

PhD students are learning to research.

The only group not included in "professors" is "postdocs" then, who are temporary staff who usually leave academia after a year or two.
