Hasty Generalization

Hasty Generalization Example 1

Person A: This young fella bagging my groceries didn’t look me in the eye, didn’t smile, didn’t say anything to me when I told him to have a nice day. Kids these days have no respect.

In this example, Person A makes a hasty generalization. Based on one anecdotal experience, Person A draws a conclusion about “kids these days” which is extremely broad. The conclusion does not match the evidence.

Why Hasty Generalization Is a Fallacy

The flaw with a hasty generalization is the lack of sufficient evidence. Broad claims require broad evidence, and so on.

If Person B claims, “I saw a brown car, therefore all cars are brown,” that is obviously absurd. This is a hasty generalization, where Person B uses only a small piece of evidence to draw a conclusion about a lot more.

When someone generalizes in this way, they are assuming things. Hasty generalizations are often borne from anecdotes, which are dubious pieces of evidence.

Hasty Generalization Example 2

Here is another brief example of a hasty generalization.

Person A: There’s an awful lot of crime in this part of town. The folks around here are criminals.

For the sake of analysis, let's say that the first part, “there’s an awful lot of crime in this part of town,” is statistically accurate. The hasty generalization occurs in the second part, then, when Person A uses insufficient evidence to draw a large conclusion about “folks” in the area.

In order to be accurate, Person A needs to be specific in their claims, and they need to clearly link their evidence to those claims.

When it comes to formulating conclusions, don't make mountains out of molehills!

Example of Hasty Generalization (Essay Quote)

Not all examples of hasty generalization are short or obvious. Sometimes, they are employed in essays and articles. When this happens, they can be harder to spot. Here’s an essay paragraph that employs the hasty generalization in a sneakier way.

Can you identify the hasty generalization? Remember, what conclusion does not match the evidence provided?

The answer: “Clearly, Tuwey has a problem with buildings and construction.”

This is a hasty generalization because the evidence only supports the contention that Tuwey doesn’t approve of building in the nature reserve. It doesn’t support a conclusion that he is broadly against buildings and construction.

Because this generalization is hasty, it would be very easy for the essayist to get off track at this point, and continue down a line of reasoning that is flawed. The brief and unassuming nature of a hasty generalization is a big reason why you have to be so careful every time you draw a conclusion.

Fig. 2 = One flaw to start them all.

Tips to Avoid Hasty Generalization

When writing your own essay, here are some tips to avoid making this logical fallacy.

Slow Down to Avoid Hasty Generalization

The word “hasty” is in the name of the fallacy for a reason.

When you are writing, don’t jump to your conclusion because you feel pushed or are in a rush. If you don’t slow down to make sure that your logic is straight, you will get ahead of yourself, and you might find that you have hastily generalized a book, a group, or a character.

The Scale Test to Avoid Hasty Generalization

Whenever you draw a conclusion in your essay, immediately stop and apply the scale test. This is a very easy test:

Big claim = a lot of evidence, small claim = not much evidence.

If you use a word like “all” or “most” in a conclusion, be sure that your evidence scales. Does it cover “all” or “most” things? It probably won’t scale, so try to make a smaller and more specific claim.

Smaller and more specific claims don’t need as much evidence. One to three pieces of evidence should suffice.

Support multiple smaller points using logical evidence. Then, as you verify these points, use them to support your thesis statement.

Erase Preconceptions to Avoid Hasty Generalization

When preconceptions creep into your essay, they corrode your logic. This is because they have a way of moving your argument along in your own head, when the argument doesn't progress without written evidence. Preconceptions become unstated conclusions, and that will not do when all your conclusions require valid support.

For example, if you don’t like a character in a story, don’t write about the character with the underlying assumption that your reader doesn’t like them. Keep your reader in the loop at all times.

Preconceptions are also dangerous because they can be supported by fallacious evidence and opinions. Bigotry, for example, is based on faulty preconceptions.

Synonyms for Hasty Generalization

You might hear this fallacy referenced by other names, including the “faulty generalization," “sweeping generalization,” and an “argument from small numbers.” In Latin, this kind of argument is called dicto simpliciter.

The hasty generalization is an example of jumping to conclusions. When you jump to conclusions, you fail to take the necessary time to procure evidence in order to draw your conclusion.

Although not synonymous, racism and other forms of bigotry commonly result from hasty generalizations.

Hasty generalizations are not glittering generalities. A glittering generality is a form of propaganda. It is not a logical fallacy. A glittering generality is a slogan such as "Believe In Change." It sounds positive and forward-moving, but is devoid of content.
