The above argument is considered strong because John’s probability of a fair complexion is high. Weak Argument. A weak argument is an inductive argument that fails to have its conclusion be probably true, even given the truth of the premises. Example. Most Germans have a fair complexion. John has a fair complexion. Therefore, John is a German
A strong argument is an inductive argument that succeeds in having its conclusion be probably true, given the truth of the premises. A weak argument is an inductive argument that fails in having its conclusion be probably true, even given the truth of the premises. With this in mind, let’s next see how we can identify inductive arguments.
Inductive arguments are said to be either strong or weak. There’s no absolute cut-off between strength and weakness, but some arguments will be very strong and others very weak, so the distinction is still useful even if it is not precise. A strong argument is one where, if the premises were true, the conclusion would be very likely to be true.
5.1: Prelude to Inductive Arguments; 5.2: Cogency and Strong Arguments Inductive arguments are said to be either strong or weak. There’s no absolute cut-off between strength and weakness, but some arguments will be very strong and others very weak, so the distinction is still useful even if it is not precise.
Inductively strong arguments cannot have: Actually true premises and actually false conclusion; To summarize, a strong inductive argument is one where it is improbable for the conclusion to be false, given that the premises are true. A weak inductive argument is one where the conclusion probably would not follow from the premises, if they were ...
By contrast, an inductively strong argument with true premises provides good, but not conclusive, grounds for its conclusion. ... Inductively strong; Inductively weak; Worthless; General and Particular. It’s not unusual (particularly if you’re trying to learn logic using YouTube) to see deductively valid arguments described as proceeding ...
So, the strengths of inductive arguments range from very weak to very strong. This chapter focuses specifically on the nature of the inductive process because inductive arguments play such a central role in our lives. We will begin with a very important and very common kind of inductive argument, generalizing from a sample. ...
The most important part is that an argument should have reason in it and that reason should be relevant to the given situation. . A strong argument will always have ‘why’ in it. Weak argument: A weak argument is the one which is illogical, impractical and irrelevant. Also, extreme statements and examples are weak arguments.
Something that worked in the past may not work in the future. We want to make decisions backed by evidence that lesson risk and increase the probability of success. We want what we will call strong inductive arguments. We want to avoid weak inductive arguments. Very strong inductive conclusions = reliable beliefs. (See the optional tutorial for ...
The first idea that one might have to define inductively strong arguments is: X ⇒ Y X\Rightarrow Y X ⇒ Y is inductively strong when X → Y X\rightarrow Y X → Y is probable. To say that a formula is "probable" means that the probability of the formula is above some threshold. For instance, the probability of the formula is greater than 0. ...
In the next section, we concentrate on arguments that are deductively strong but inductively weak. 13 1.2 Deductively Correct and Inductively Weak Arguments Rips (2001) also provides a priori arguments for why, when the probability of the conclusion given the premise is 1, the argument is not necessarily deductively correct—although if it is ...
The primary goal in argumentation is for the conclusion to follow from its basic premises either with certainty or with high probability. Technically, this means the arguer desires the argument to be deductively valid or to be inductively strong. The concept of deductive validity can be given alternative definitions to help you grasp the concept.
Inductive arguments are arguments judged by the inductive standard of, "Do the premises make the conclusion probable?" So the strengths of inductive arguments range from very weak to very strong. With inductively strong arguments there is a small probability that the conclusion is false even if the premises are true, unlike with deductively ...
An weak argument is one in which it is not probable that if the premises are true, then the conclusion is true. • For example 2. Exactly 50% of 30-year-old American women live to be 80. ... either a weak argument or a strong argument with a false premise. • Every argument with a valid form is valid, but strength is not ensured
A strong argument is one where the premises provide substantial support for the conclusion, making it likely to be true, while a weak argument has premises that do not adequately support its conclusion, making it less likely to be true. This distinction is crucial in evaluating inductive reasoning, as it helps to determine how persuasive and credible an argument is based on the evidence provided.
An inductive argument is inductively strong when you have the following: If all its premises were true, then it its highly likely or probable that its conclusion would also true. "Strong" and "weak" are the terms used to describe the possibilities for the logical strength of inductive arguments. To determine if an argument is strong or weak:

Inductively strong arguments and reasons can take many different forms; in this module, we will focus on those that involve probability. We can also speak of inductively strong reasons. A group of sentences provide inductive reasons for a conclusion just in case it is unlikely for all of them to be true and the conclusion false.
