There are the facts which may be hard to find or observe.
Then there is the logic that we use to handle the facts.
It might be interesting to briefly review some logical fallacies here.
From Wikipedia:
logical fallacies
Though often used unintentionally, so-called fallacies can be used purposefully to win arguments. Such rhetorical devices, discussed in more detail below, are: "ignoring the question" to divert argument to unrelated issues using a red herring; making the argument personal (argumentum ad hominem) and discrediting the opposition's character, "begging the question" (petitio principi), the use of the non-sequitur, false cause and effect (post hoc ergo propter hoc), bandwagoning (everyone says so), the "false dilemma" or "either-or fallacy" in which the situation is oversimplified, "card-stacking" or selective use of facts, "false equivalence", and "false analogy". Another common device is the "false generalization", an abstraction of the argument that shifts discussion to platitudes where the facts of the matter are lost. There are many more tricks to divert attention from careful exploration of a subject.[1]
