Examples of FALLACIOUS
“Bad legislation and fallacious arguments are threatening our most renowned educational institutions, which have made major contributions to our understanding of science and society and to our health and economic well-being, institutions that are the envy of the world.” — Burton G.

Did You Know?
It will come as no surprise that fallacious is related to the noun fallacy, meaning “delusion” or “falsehood.” Both words come from the Latin word fallacia, which in turn comes from fallere, meaning “to deceive.” (Other descendants of fallere in English include fail, false, and fault.) Fallacious arguments are a hot topic among philosophers, and some classic examples include the “ad hominem” fallacy, the “slippery slope” fallacy, and the “red herring” fallacy.
