[Standard] Logical Connection / Causal Link [Why it's important] 
Without a proposed and demonstrated mechanism between an asserted cause and effect, there's no way to demonstrate that it's anything more than a coincidence. The causal link between flipping a light switch and the light coming on is that the flow of electricity is allowed to the light bulb, which lights up. This causal link can be easily demonstrated. Conversely, what is the causal link between burying a statue of St. Anthony upside down by the "for sale" sign for the house that's on the market, and the house selling faster, and how would one demonstrate this causal link? Without the causal link, it's a form of post hoc ergo propter hoc to assert that they're connected.
