Present An Example Of An Unsound Valid Deductive Argument
Present An Example Of An Unsound Valid Deductive Argument And A Sound
Present an example of an unsound valid deductive argument and a sound valid deductive argument from the media. Outline both arguments presenting the premises and the conclusions of both. Explain why you believe the arguments are sound and unsound. Include a URL to the arguments drawn from a media source. You may draw from the week’s required multimedia for examples. If you are unable to locate examples from the media, you may identify arguments from your life. After you have presented your deductive examples, present an example of an inductive argument from the media and determine whether it is strong or weak. Explain your reasoning about why it is strong or weak, and then explain how the argument might be strengthened. Include a URL to the argument drawn from a media source. If you are unable to locate examples from the media, you may identify an argument from your life. You must post to this discussion on at least four separate days of the week and your posts must total at least 400 words as you address the questions noted above. Your first post must be completed by Day 3 (Thursday) and the remainder of your posts must be completed by Day 7 (Monday). You must answer all aspects of the prompt at some point during the week. Also, be sure to reply to your classmates and instructor. Try to attempt to take the conversation further by examining their claims or arguments in more depth or responding to the posts that they make to you. Keep the discussion on target and try to analyze things in as much detail as you can.
Paper For Above instruction
In evaluating logical arguments, the distinction between soundness and validity is crucial. A deductive argument is valid if its conclusion logically follows from its premises, regardless of the truth of those premises. An argument is sound if it is both valid and its premises are true. To illustrate these concepts, I will present examples of both an unsound valid deductive argument and a sound deductive argument based on media sources, along with an analysis of each.
Example of an Unsound Valid Deductive Argument
Consider the following argument originating from a media article:
- Premise 1: All actors are celebrities.
- Premise 2: Some celebrities are politicians.
- Conclusion: Therefore, all actors are politicians.
This argument is invalid because the conclusion does not necessarily follow from the premises. However, if we modify the reasoning to make it valid (for instance, by stating "All actors are celebrities" and "All celebrities are politicians," leading to "All actors are politicians"), the structure becomes valid. But in the original case, the argument's invalidity means it is not guaranteed to be true, regardless of the truth of the premises. Also, since the conclusion does not follow validly, it is unsound as a deductive argument.
A real-world media example can be cited from a news report claiming, "Since all birds can fly and penguins are birds, penguins can fly." Here, the argument is invalid because the premise "All birds can fly" is false, rendering the conclusion false. Its invalidity invalidates its deductive status, and thus, it is also unsound.

Example of a Sound Deductive Argument
From the media, an example of a valid and true argument can be framed as follows:
- Premise 1: All humans are mortal.
- Premise 2: Socrates was a human.
- Conclusion: Therefore, Socrates is mortal.
This argument is classic and well-known in logic. Its form is valid, and both premises are true, making the argument sound.

Analysis of Soundness and Validity
The first example demonstrates an invalid argument with false premises, hence unsound. The second example shows a valid argument with true premises, thus it is also sound. Correctly identifying whether an argument is sound depends on both the logical structure and the truth of its premises.
Inductive Argument Example from Media
An media report might state: "In a recent poll, 70% of surveyed citizens support the new policy." Based on this, one might infer that the majority of all citizens support the policy. This is an inductive argument, as it generalizes from a sample to the whole population.
This argument’s strength depends on the sample size, representativeness, and methodology of the poll. If the sample was random, sufficiently large, and representative, the argument would be considered strong. However, if the sample was biased or small, the argument would be weak.
To strengthen the argument, the media source should provide information about the polling methodology, margins of error, and whether similar polls have yielded consistent results.

Conclusion
In conclusion, understanding the difference between valid and sound deductive arguments is essential for critical thinking. Validity pertains to the logical connection between premises and conclusion, while soundness also requires the premises to be true. Similarly, inductive arguments vary in strength, which hinges on the quality and quantity of evidence. Analyzing media arguments critically enables us to assess their reliability and reasoning quality more effectively.
