It's also way too easy to publish articles that are actually completely meaningless because they have no theory in them. Say, "the correlation between posting on neogaf and being a shitheel". You get an answer alright, but it's without a process of expected explanations / predictions / hypothesis (theory), which is therefore junk information. It tells you nothing. Yet these "bullshit publications" (my words, not someone else's) do count towards credibility.
...hardly, because they are not cited that often.
A real problem in this vain though is that review articles tend to get massively overcited, whereas original research is often largely ignored.
