Logic in an Age of Persuasive Imagery: Hasty Generalization
statement aside as ludicrous, there is actually a fallacy represented here by my
hyperbolic enthusiasm for my own writing: a hasty generalization.

#1.Too small of a sample
#2. Not a representative sample
generalization because I do not have access to all the posts written on
apologetics in order to know if the post I just wrote is the best post
ever. The sample size for my inference
would be too small.
representative of the broader class which we are referencing. In our political campaign examples, a
Democrat candidate might claim that because Republican Randy Presidential
Hopeful demeans other candidates then all Republicans are demeaning to other
people; therefore a democrat cannot vote for any Republican. But Republican Randy doesn’t represent how
all Republicans would treat Democrats (or other republicans, independents, etc).
The sample size here is too small to
make an accurate judgment. However, I’ve
heard this kind of inference from members of both parties!

convention and studied 3,000 plumbers there.
They all made over $100,000 a year.[1]
Though 3,000 plumbers sounds like a big enough sample size,
the sample does not aptly represent all plumbers. What about the plumbers who do not make
enough to go to an international plumbers convention? This sample size is probably only taken from
wealthy plumbers (or plumbers able to afford attending the convention) and therefore is a hasty generalization.
generalizations; including throwing around poll percentages, tossing out
figures supporting a view, and attributing ideology to entire classes of
people. When you hear these figures you
should ask: Where are you getting that from?
What is the source of your information?
What were the control factors used in the study (ie. how many people
were surveyed and who were the people surveyed and did the survey have an apt
sample of the representative class)? These
are important questions to answer in order to avoid manipulation through the
logical fallacy of hasty generalization.

In the example above, the hidden assumption is that the person has been beating his wife. While that’s not so hidden in this question, it still presents a problem because the question is asking for a “yes” or “no” answer. Both of these replies will incriminate the responder. If a “yes” answer is given, the person is admitting he used to beat his wife. If a “no” answer is given, the person is admitting he still beats his wife.How is this a problem for candidates in the elections? Candidates are asked all sorts of loaded questions by journalists and others who interview them and moderate their debates. For example, in the 2007 Republican debates, Senators John McCain and Mike Huckabee were asked this basic question, “Do you believe in evolution? Yes or no.”
“No” – I do not believe in science.

This logical fallacy is one of the more popularly (pun intended) utilized in marketing a product. A company wants you to go out and purchase their product so they tell you how many other people have also done so. “Buy a Tough Guy truck. The number one truck in Oklahoma.” This appeal does nothing to evidence the quality of the product, it’s just an appeal to the popularity of the product. “Use BeautyGirl wrinkle cream. Voted the best wrinkle cream by Vogue magazine readers.” What is wrong with using a product, buying an item, or believing a view on the basis of its popularity? The error in reasoning is due to the fact that a position or product is not the best one for any individual just because a group of people (even a large group of people) think so. What is important is looking at the evidence these people have utilized in arriving at a conclusion about the product or view. Unless the group has some kind of special knowledge (such as they all work for a consumer watch company), it is fallacious to ascribe authority to their view.An everyday example: Gossip can fall into this category when a person uses the phrases “some people” or “the word on the street” or “they say” in order to prove or argue for a point. Remember, good reasons (good data) must be brought as evidence for an argument, not just a group of people’s preferences or opinions; especially not an anonymous group of people such as “they.” A political campaign example: Political campaigns utilize this strategy when they use the opinions of the American populace to support their platform: “Seventy-five percent of Americans say they will vote for Senator George Washington in the upcoming presidential election. Therefore, Washington is the best candidate!” The problem with polls and percentages is that though they may reflect a group of people’s opinion on an issue or on a person, the poll itself does not prove that the candidate is therefore the best choice for any individual voter. However, candidates misuse the polls as evidence that they are the better choice for voters. When choosing the best candidate for your individual vote, you need evidence that the candidate will legislate according to what you think is best for the nation. Popularity is not an evidential factor for legislative ideology. I’m sure you have seen this type of fallacy in use already as we approach the upcoming 2012 elections.Resources for recognizing fallacies:
committed when the Christian avoided the atheist’s actual argument and put forth a response to a different argument. The Christian focused on this issue: that the atheist did not desire to know truth. In doing so, the Christian is irresponsible in representing the atheist’s actual argument (the problem of evil), and therefore irresponsible to represent the truth. Notice that the atheist offered a reasonable objection to the existence of a good God, and the Christian did nothing to even acknowledge the atheist’s argument. This is not being a good ambassador for the Lord Jesus Christ, who is the truth. Jesus did not avoid questions. He sought to engage people with a deeper understanding of the questions they asked (Matthew 22).
