The relevant part was his status as a APP student, so that's what I would go with for the headline. Using an irrelevant bit because it will get more clicks seems to fall under the "click bait" domain, especially when he was a grad from CS, not a current major. Personally I would be more interested to know that it was a newbie student to an academic field debunked a core tenet. "New APP Students Debunks Core APP Finding" is much more interesting to me than a coincidence of the former academics pursuits with mine. It implies the question, "If a brand new student to the field saw this error so quickly, why didn't anyone else?"
