I don't think it's fear as much as being spoiled. Sure a student dreads failing an exam, but there's a lot of machinery starting up every time that fear is invoked, to find apologies and calm, soothing prospects on how it's going to work out eventually. That machinery existing, not even running through to a satisfying result, is comforting enough to overrule the fear. The oversized emotional attachment the article mentions must relate to the activities done instead of the thing which apparently too little emotion is attached. What is called Fear of Missing Out.
