Examples of Fallacies
Fallacies are
defined as mistakes in belief based on an unsound argument. There are many
different types of such mistakes that can occur.
Fallacies in Arguments
Here are some examples of fallacies you
may encounter when making an argument:
·
Appeal to Ignorance - An appeal to ignorance occurs when one
person uses another person’s lack of knowledge on a particular subject as
evidence that their own argument is correct.
For example: “You can’t prove that
there aren’t Martians living in caves under the surface of Mars, so it is
reasonable for me to believe there are.”
·
Appeal to Authority - This type of fallacy is also referred to
as Argumentum ad Verecundia (argument from modesty). In this case, rather than
focusing on the merits of an argument, the arguer will try to attach their
argument to a person of authority in an attempt to give credence to their
argument.
For example: “Well, Isaac Newton
believed in Alchemy, do you think you know more than Isaac Newton?”
·
Appeal to Popular Opinion - This type of appeal is when someone
claims that an idea or belief is true simply because it is what most people
believe.
For example: “Lots of people bought
this album, so it must be good.”
·
Association Fallacy -
Sometimes called "guilt by association," this occurs when someone
links a specific idea or practice with something or someone negative in order
to infer guilt on another person.
For example: “Hitler was a vegetarian,
therefore, I don’t trust vegetarians.”
·
Attacking the Person - Also known as Argumentum ad Hominem
(argument against the man), this is quite a common occurrence in debates and
refers to a person who substitutes a rebuttal with a personal insult.
For example: “Don’t listen to Eddie’s
arguments on education, he’s an idiot.”
·
Begging the Question -
This type of fallacy is when the conclusion of an argument is assumed in the
phrasing of the question itself.
For example: “If aliens didn’t steal
my newspaper, who did?” (assume that the newspaper was actually stolen).
·
Circular Argument -
Also referred to as Circulus in Probando, this fallacy is when an argument
takes its proof from a factor within the argument itself, rather than from an
external one.
For example: “I believe that Frosted
Flakes are great because it says so on the Frosted Flakes packaging.”
·
Correlation Implies Causation Fallacy - Otherwise known as Cum
Hoc Ergo Propter Hoc, this is a fallacy in which the person making the argument
connects two events which happen sequentially and assumes that one caused the
other.
For example: “I saw a magpie and ten
minutes later, I crashed my car, therefore, magpies are bad luck.”
·
False Dilemma/Dichotomy - Sometimes referred to as Bifurcation,
this type of fallacy occurs when someone presents their argument in such a way
that there are only two possible options.
For example: “If you don’t vote for
this candidate, you must be a Communist.”
·
Non Sequitur - A fallacy wherein someone asserts a conclusion
that does not follow from the propositions.
For example: “All Dubliners are from
Ireland. Ronan is not a Dubliner, therefore, he is not Irish.”
·
Slippery Slope - Assuming that a very small action will
inevitably lead to extreme and often ludicrous outcomes.
For example: “If we allow gay people
to get married, what’s next? Allowing people to marry their dogs?”
As you can see,
there are many different types of fallacies that you may encounter. Arguing
with someone who uses false logic like this can be a frustrating experience,
but now that you know these are examples of fallacies, you can identify what
they are doing and spot the lapse in logic right away.
