At the university I have met 2 types of professors. The first type will explain the new topic in very academic and strictly professional way. The second type will explain the topic in a plain language, in a very easy-to-understand way. If I look at it from the perspective of countersignaling, I would describe the first type as contrarian and the second type as meta-contrarian. My observation is also that the contrarian would be usually younger professor in his late thirties or forties, and meta-contrarian would be professor in his sixties and up.
