Genetic fallacies (For instance: The appeal to novelty (also called argumentum ad novitatem) is a fallacy in which someone prematurely claims that an idea or proposal is correct or superior, exclusively because it is new and modern. In a controversy between status quo and new inventions, an appeal to novelty argument isn’t in itself a valid argument. The fallacy may take two forms: overestimating the new and modern, prematurely and without investigation assuming it to be best-case, or underestimating status quo, prematurely and without investigation assuming it to be worst-case.)
