Of course, if we have evidence showing that P is the only or most likely condition that leads to Q, then we can infer that P is likely to be true without committing a fallacy. But if we argue from his being late to there being a traffic jam, we are guilty of this fallacy - the colleague may be late due to a faulty alarm clock. For example, if there is a traffic jam, a colleague may be late for work. The problem with this type of reasoning is that it ignores the possibility that there are other conditions apart from P that might lead to Q. Inferring that P is true solely because Q is true and it is also true that if P is true, Q is true. Surely you have heard of commercials implying that we should buy a certain product because it has made to the top of a sales rank, or because the brand is the city's 'favourite'. This is the fallacy committed by many commercials. The truth of a claim is established only on the basis of its popularity and familiarity. Of course, pity might be a relevant consideration in certainĬonditions, as in contexts involving charity. a student argues that the teacher should let him/her pass the examination because he/she needs it in order to graduate. Usually this happens when people argue for special treatment on the basis of their need. In offering an argument, pity is appealed to. Notice also that this fallacy does not apply to situations where there are only two rival claims and one has already been falsified, then we may justly establish the truth of the other even if we cannot find evidence for or against it. But notice, as in cases like this, there is evidence for the law, namely positive instances. the first law of thermodynamics holds because so far there has not been any negative instance that would serve as evidence against it. At first sight it seems that many theories that we describe as scientific involve such a fallacy. A simple obvious example of such fallacy is to argue that unicorns exist because there is no evidence against such a claim. The truth of a claim is established only on the basis of lack of evidence against it.

You say that only because you cannot find a good job. Example:Ī: The Government should enact minimum-wage legislation so that workers are not exploited.ī: Nonsense. Here are some examples of common fallacies:Ī theory is discarded not because of any evidence against it or lack of evidence for it, but because of the person who argues for it.
