I address them here. I have divided them -- and this is strictly my own personal ordering -- into those I have found cogent and those I have not. Uncogent objections Wikipedia is WP:
We add condition 3 for inductive strength because at best, cogent arguments would make their conclusions likely to be true if their premises are true. But there could still be a possibility that the premises are true but the conclusion is false.
And S might have information that indicates that this is what has happened. So consider Ellen who has read a New York Times article that cites several reputable studies that have found that most people in her neighborhood in Brooklyn are Democrats.
Then Ellen considers her neighbor Amy. She doesn't have any particular reason Uncogent argument doubt that Amy is an exception, or in the non-Democrat minority. Most people who live in Brooklyn are Democrats.
Amy lives in Brooklyn. Therefore, Amy is a Democrat. But Michael, who also knows Amy, and who knows that Amy lives in Brooklyn, has listened to lots of anti-Democrat tirades from Amy. He's heard her say that she's a Republican and that she wouldn't be a Democrat if held a gun to her head.
And he thinks she's sincere. Notice that the premises are true and that they are reasonable for Michael to believe; the argument is not weak because he rejects a premise. Weak Arguments Given the way we are analyzing arguments, there are several ways that they can be weak.
First, a weak argument is neither deductively strong, nor inductively strong. That is, weak, deductively strong, and inductively strong are all mutually exclusive categories. Every argument must be one of these three.
That is, if she thinks any premise is false, or if she suspends judgments about any premise, then that argument is weak. So consider this argument: Therefore, Arnold Schwartzenengger is male.
If I'm evaluating the strength of this argument, I'd have to point out that premises 1 is false because there are many CSUS students who are female. In fact, according to the last demographic information I saw on this from the administration, most CSUS students are female.
I also believe that premise 2 is false. He's a rich movie star. I don't think he is seeking a degree, and certainly not at CSUS. So the argument is weak because of both premises. An ill-formed argument is neither valid nor cogent.
So consider this example: This argument is invalid. Even if the premises were true, the conclusion would not be guaranteed to be true.

For example, All men have ten fingers. John is a man. Therefore, John has ten fingers. This argument is logical and valid. However, the premise "All men have ten fingers.". An inductive argument is cogent when the argument is strong and the premises are true. An inductive argument is uncogent if either or both of the following conditions hold: the argument is weak, or the argument has at least one false premise.
Suppose all CSUS students were male. Schwartzenegger is a male. But that fact alone isn't enough to suggest that he's a student at CSUS.
It's an instance of affirming the consequent, a logical fallacy. Defeat happens in the specific circumstances listed above under Inductively Strong arguments.Campus Rape: The Problem With 'Yes Means Yes' New students at San Diego State University watch a video on sexual consent during an orientation meeting, Aug.
