******** REMINDERS ********
* A LOGICAL FALLACY is a mistake in reasoning that leads
one to come to a fallacious conclusion.
============
two basic TYPES/categories of logical fallacies
============
* A FALLACY OF RELEVANCE is one where the arguer offers
LOGICALLY IRRELEVANT reasons to support the conclusion.
* This is covered in Chapter 5 of the text.
* A FALLACY OF INSUFFICIENT EVIDENCE is one where the premises
may be relevant, but DON'T PROVIDE SUFFICIENT EVIDENCE to
support the conclusion.
* This is covered in Chapter 6 of the text.
******** end of REMINDERS ********
* now, here are a few MORE logical fallacies of insufficient
evidence:
------------
False Alternatives
------------
* An arguer poses a simple, yet false, either-or choice
* sometimes these are stated in if-then terms, also
------------
Loaded Questions
------------
* A question (or statement) that contains an unfair or questionable
assumption, no matter what the response
* often, cramming several questions into that one
loaded question;
* how can one respond?
...it helps to distinguish between the actual embedded
questions and respond to each individually,
NOT starting with "Yes" or "No"...
since a loaded question is complex,
(containing multiple embedded questions),
it needs a complex response;
or if necessary, a calm "That's a loaded question. ..."
------------
Questionable Cause
------------
* attributing something as being the cause of something else
without sufficient evidence
* THREE types of Questionable Cause:
* Post Hoc Fallacy
* Post Hoc Ergo Propter Hoc – "AFTER the thing,
therefore BECAUSE of the thing"
* B happened AFTER A, so A must've CAUSED B to happen
* Correlation Fallacy
* A and B (regularly/frequently) OCCUR TOGETHER,
so A CAUSES B"
(or B CAUSES A)
* Correlation is NOT equal to Causation !!!
* A very humorous Correlation Fallacy Website:
http://www.tylervigen.com/spurious-correlations
* Oversimplified Cause Fallacy
* Claiming that "A causes B" when in fact, B may occur
for any of several different reasons
------------
Hasty Generalization
------------
* Claiming something is true of an entire group after
only a few examples
* (similar to stereotyping)
* we commit this fallacy when we draw a GENERAL
conclusion from a sample that is BIASED or
TOO SMALL
------------
Slippery Slope
------------
* Claiming, **without sufficient evidence**, that a
seemingly harmless or mild action will lead, if continued,
to a harmful or disastrous outcome.
* "This is just the first (or next) step down a path that will
lead to horrific consequences!"

------------
Weak Analogy
------------
* The claim in which an arguer compares two or more things that
aren't really comparable in relevant respects.
------------
Inconsistency
------------
* Making two or more statements within the same argument
(or similar arguments) that cannot both simultaneously be
true or have an innate contradiction
