Faulty cause and effect is a logical fallacy and propaganda technique in which someone wrongly concludes that just because two events follow each other, one of those events is the reason the other happened. This fallacy can also be applied to sets of data. Someone may use such an argument when they're strongly against something and are seeking justification for the position.
Similar to faulty cause and effect is a false analogy, which occurs hen a person claims two things are much alike when that may not be case. Like all propaganda techniques, people use faulty cause and effect and false analogies to appeal to the audience's emotions so that they take a specific action or hold a certain belief.
