Fallacies Flashcards
Fallacy
Defects that weaken arguments
Hasty Generalization
Making assumptions about a whole group or range of cases based on a sample that is inadequate.
Missing the Point
Premises of an argument do support a particular conclusion - but not the conclusion that the arguer actually draws
Post Hoc
Assuming that because B comes after A, A caused B. Of course, sometimes one event really does cause another one that comes later.
Slippery Slope
The arguer claims that a sort of chain reaction, usually ending in some dire consequence, will take place, but there’s really not enough evidence for that assumption.
Weak Anology
Many arguments rely on an analogy between two or more objects, ideas, or situations. If the two things that are being compared aren’t really alike in the relevant respects, the analogy is a weak one, and the argument that relies on it commits the fallacy of weak analogy.
Appeal to Authority
Often we add strength to our arguments by referring to respected sources or authorities and explaining their positions on the issues we’re discussing. If, however, we try to get readers to agree with us simply by impressing them with a famous name or by appealing to a supposed authority who really isn’t much of an expert, we commit the fallacy of appeal of authority.
Straw Man
In the straw man fallacy, the arguer sets up a weak version of the opponent’s position and tries to score points by knocking it down.
Red Herring
Partway through an argument, the arguer goes off on a tangent, raising a side issue that distracts the audience from what’s really at stake. Often, the arguer never returns to the original issue.
False Dichotomy
In false dichotomy, the arguer sets up the situation so it looks like there are only two choices. The arguer then eliminates one of the choices, so it seems that we are left with only one option; the one the arguer wanted us to pick in the first place.
Fallacies of Relevance
These fallacies appeal to evidence or examples that are not relevant to the argument at hand.
Appeal to Force
This argument uses force to make the audience accept a conclusion. It commonly appears as a last resort when evidence or rational arguments fail to convince a reader.
Genetic Fallacy
The genetic fallacy is the claim that an idea, product, or person must be untrustworthy because of its racial, geographic, or ethnic origin.
Personal Attack
Attacking or praising the people who make an argument, rather than discussing the argument itself.
Abusive
To argue that proposals, assertions, or arguments must be false or dangerous because they originate with atheists, Christians, Muslims, communists, capitalists, the John Birch Society, Catholics, anti-Catholics, racists, anti-racists, feminists, misogynists (or any other group) is fallacious.
