Caution: Slippery Slopes Ahead!

LeBron James drinks Sprite, so YOU should drink Sprite! Michael Phelps thinks Subways is delicious, so of course you agree! Right? Joe Flacco loves Gummy Bears … you probably get the idea. And you can undoubtedly list many other examples of advertisers who attempt to sell products based on the “authority” of celebrity endorsements. Hence, this logical fallacy is known as the appeal to authority.


Another common fallacy is the bandwagon appeal, which you can see anytime you pass one of the 35 thousand-plus McDonald’s that exist on the planet.The implicit argument here is “99 BILLION” people can’t be wrong! In other words, if everyone is doing something, so should you.

But have you ever considered the strength of your arguments when you write essays for your English or Business courses? If not, now is a great time to learn about the many ways arguments can be flawed so you can work on making yours stronger. Check out this awesome poster that includes an exhaustive list (and nice graphics) of various logical fallacies, including the titular slippery slope preceding this post. And the next time you’re watching a commercial, see if you can identify one of these fallacies in the ad’s argument.
