Informal Logical Fallacies


    A logical fallacy refers to a rationally weak argument that is widely and successfully used. Informal logical fallacies are inferential arguments whose irrationality can be identified from the content of the discussion board post . Thus, formal-logical fallacies focus on the argument form while informal logical fallacies concentrate on the logic of the language used. Concisely, the premises of informal logical fallacies do not support the proposed conclusion. The following discussion provides three instances of informal logical fallacies I have experienced and explains how the mentioned mistakes could have been avoided.

    In my lifetime, I have observed informal logical fallacies from the media and experienced misconceptions in exchanging ideas with friends. Once, I discussed men’s suits with my friend, and my associate made an observation that many Hollywood stars and even the American president wear Italian designer suits. Subsequently, he made a conclusion that Italians are the best manufacturers of the most coveted men’s fashion attires in the world. The resultant conclusion is logically weak because other factors could as well elucidate their choice of suits. He could have avoided this fallacy, not focusing on certain people in his speculations.

    Second instance of misperception occurred when my Muslim friend argued that Christians are mean. After enquiring from him why he had made such a conclusion, he explained to me that he had a Christian neighbor who was mean. This is another example of informal logical fallacy because despite a true premise, the conclusion is absurd. He could have avoided the logical error by shunning hasty generalization.

    Finally, my classmate once told me that sunny days are the best because he does not have to carry an umbrella when coming to lectures. The conclusion is wrong because lack of rain would lead to more devastating consequences than carrying an umbrella during the rainy season. He could have avoided making such a deduction by circumventing general conclusions from exceptional situations.

    To sum up, people should be careful not to make wrong conclusions due to reliance on untrustworthy premises. One should avoid making general conclusions from exceptional circumstances. Hasty deductions should be eluded as they are likely to be rationally weak
