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.

An Unsound Valid Deductive Argument Sample Answer

A deductive argument is a reason that is meant to be valid by the arguer. The argument is intended to provide a guarantee of the truth of the conclusion given that the argument’s assumptions are true. In a deductive argument, the assumptions are designed to provide substantial support for the conclusion.  Therefore, if the assumptions are true, then there is no way the conclusion can be false. Hence, an argument is said to be sound if a valid argument has true premises. Also, a case is said to be unsound if a valid argument has a false conclusion.

The premises of an argument do not need to be true in order for the argument to be valid. The argument is valid if the premises and conclusion link correctly with one other. Therefore, if the premises were true, the conclusion would have to be true as well. The following examples are valid but unsound arguments:

All toasters have gold.

All golden items are time-travel devices.

Therefore, all toasters ate time-travel devices.

Obviously, the assumptions in the above examples are not true. It may be difficult to imagine these premises being true, but it is not difficult to see that if they were true then their truth would logically make the conclusion true as well. A sound argument is one that is valid and begins with premises that are true. The following argument is of a valid nature and also reliable

No felons are eligible voters.

Some professional athletes are said to be felons.

Therefore, some professional athletes are not allowed to be voters.

In the above examples, not only do the assumptions give the right sort of support for the conclusion, but the premises contain truth in them. Therefore, that is the conclusion. Also, an inductive argument is an argument intended to increase the probability of its conclusion. Here, the premises are firm therefore if they were true the so as the conclusion. The following is a strong inductive argument:

Two witnesses said John committed the murder. John’s fingerprints are all over the murder weapon. John confessed to the crime. So, John committed the murder.

The relationship the author of the arguments takes to exist between the premises and the conclusion is what differentiates inductive and deductive arguments.  If the author of the argument has no doubt that the truth of the assumption establishes the truth of the conclusion, then the case is deductive and vice versa (IEP, 2003).
