You don't put science on your name if you're a real science
Having flashbacks to when a close friend was getting an MS in Political Science, and spent the first semester in a class devoted to whether or not political science is a science.
"Information science" is basically long form of "informatics" so that breaks it I'd say. Also, "information" tends to imply a focus on state and places computational aspects (operations performed on information) as second hand.
I've yet to find a classification I really like but this is an interesting take. I still tend to like CIS (Computing and Information Sciences). The problem with CS is it focuses on computation and puts state as second class. The problem with IS is it focuses on state and puts computing as second class. To me, both are equally important.
It's not about computers and "You don't put science on your name if you're a real science"
He prefers the name informatics.
