I don't think this can be true, except for experts. In the biography of Oppenheimer, American Prometheus, he was described as having an uncanny ability to flip through publications and understand their conclusion and significance in seconds. That description, or anything like it, certainly isn't true for me. I would suggest that any paper that you perceive as a waste of time or not worth reading with care probably isn't worth reading at all. If it is the case that this sort of thing is the norm, as I know full well it is in some disciplines, then that says something important about what's being published in that discipline. It says nothing about what the best way to read and understand the latest pubs in a discipline with real research going on.
