"Cogno-intellectual" was the catchphrase for this when I was in school. See Abrahams et al.:

We invite you to take part in a large-scale language experiment. It concerns the word "cogno-intellectual." This noble word can be used as an adjective or as a noun. We just invented it. The fact that "cogno-intellectual" has no meaning makes it a useful word. Meaning nothing, it can be used for anything.

Here is the experiment. Use the word "cogno-intellectual" in written and oral communications with colleagues, especially with colleagues whom you do not know well. If you are a student, use it with your most impressable teachers. If you are a teacher, use it with your most impressable administrators. Use it at meetings. Use it with significant strangers. Use it with abandon. Use it with panache. The main thing is: use it.
