Authors tend to implement fallacies into their pieces to distract the reader from the lack of sound reasoning or support that they have for their conclusion. One example of a logical fallacy is an ad hominem attack; where a persons characteristics are subjected to attack by an opponent and used as support for a faulty conclusion. An example of this is Forbes piece on Benazir Bhutto called “Power Dressing How women Use Fashion in Politics: How Bhutto used the Shalwar Kameez”.

The author’s logic proceeds as Bhutto rejected the traditional women’s dress in Pakistan (the burka) and opted for the shalwar kameez. This led to her incarceration and exile. The author suggests that the reason for Bhutto’s political exile and detainment was her defiance of the traditional way of dress, not for her actions while she ruled as the Prime Minister of Pakistan.

An example of a rhetorical fallacy is an appeal to ethics rather than sound reasoning to support a conclusion. This article on abortions states that abortion is wrong because God says it is murder.

The article doesn’t employ scientific evidence to support the author’s claim that abortion is morally wrong. Instead the author uses psalms from the bible to support the word of God as ‘support’ for why abortion is wrong. The Lord has said, “”You shall not murder,” (Exodus 20:13). The life that is growing within the mother is a child, a baby.” The author is appealing to religion or ethics to support a conclusion that does not logically follow from his logic. He states that a fetus in a womb is actually called a baby, cause the Lord says it is, and therefore if it is a baby and not a fetus a woman is committing murder by undergoing an abortion.
