In todays world of research we find links/connections with a lot of different things, some are recorded in scientific journals or articles etc. regardless of whether the link is significant in causation.
Its important to understand how to identify the purpose of an article or a scientific document in order to properly comment or discuss it. Immediate dismissal of research, assuming the purpose is to indicate a conclusion due to a link for example is inappropriate. Identifying purpose in a study also prevents red herrings which allows progress in maintaining a philosophy of gaining as many true beliefs and as few false ones as possible. A red herring might result in dismissing an entire article due to fixation on irrelevant points or having a concern with something that is unrelated to the conclusion. The article might not even have a necessary conclusion related to a scientific theory it might just be a piece of data that can be used if new data arrives to formulate a theory.
Studies of correlation that do not talk of conclusive causation are not indicating a particular bias that one causes the other, or is linked to something bad therefore the other is negative as well and etc.... and if causation is inferred it usually must reference other studies to the linked objects of reference, and present a control.
I was posting a bunch of what I had written down but accidentally posted it and didn't mean to so instead ill just post some introductory material as that was not even close to being done edited and added onto.
