Determining cause and effect is not a simple feat.
From Dictionary of Philosophy
Mill’s methods: Inductive methods formulated by John Stuart Mill for the discovery of causal relations between phenomena.
Method of Agreement: If two or more instances of the phenomenon under investigation have only one circumstance in common, the circumstance in which alone all the instances agree, is the cause (or effect) of the given phenomenon.
