We can either agree with Barbara's plan, or just let the project fail. This fallacy is particularly problematic because it can lend false credence to extreme stances, ignoring opportunities for compromise or chances to re-frame the issue in a new way. Instead of acknowledging that most (if not all) issues can be thought of on a spectrum of possibilities and stances, the false dilemma fallacy asserts that there are only two mutually exclusive outcomes. This common fallacy misleads by presenting complex issues in terms of two inherently opposed sides. Example:ĭespite the fact that our Q4 numbers are much lower than usual, we should push forward using the same strategy because our CEO Barbara says this is the best approach. Just because someone in a position of power believes something to be true, doesn't make it true. Getting an authority figure to back your proposition can be a powerful addition to an existing argument, but it can't be the pillar your entire argument rests on. While appeals to authority are by no means always fallacious, they can quickly become dangerous when you rely too heavily on the opinion of a single person - especially if that person is attempting to validate something outside of their expertise.

The majority of people believe advertisers should spend more money on billboards, so billboards are objectively the best form of advertisement. While most of us expect to see bandwagon arguments in advertising (e.g., "three out of four people think X brand toothpaste cleans teeth best"), this fallacy can easily sneak its way into everyday meetings and conversations. Arguments in this style don't take into account whether or not the population validating the argument is actually qualified to do so, or if contrary evidence exists. Popularity alone is not enough to validate an argument, though it's often used as a standalone justification of validity. Just because a significant population of people believe a proposition is true, doesn't automatically make it true. Lola: You're saying we should throw our money away on external resources instead of building up our in-house design team? That's going to hurt our company in the long run. John: I think we should hire someone to redesign our website. Instead of fully addressing your actual argument, speakers relying on this fallacy present a superficially similar - but ultimately not equal - version of your real stance, helping them create the illusion of easily defeating you. This fallacy occurs when your opponent over-simplifies or misrepresents your argument (i.e., setting up a "straw man") to make it easier to attack or refute. Having an understanding of basic logical fallacies can help you more confidently parse the arguments and claims you participate in and witness on a daily basis - separating fact from sharply dressed fiction. Informal: Informal fallacies are arguments that have irrelevant or incorrect premises.Formal: Formal fallacies are arguments that have invalid structure, form, or context errors.There are two types of fallacies: formal and informal. These mistakes in reasoning typically consist of an argument and a premise that does not support the conclusion.

Logical fallacies are deceptive or false arguments that may seem stronger than they actually are due to psychological persuasion, but are proven wrong with reasoning and further examination. Our guide on logical fallacies will help you build better arguments and identify logical missteps. While some come in the form of loud, glaring inconsistencies, others can easily fly under the radar, sneaking into everyday meetings and conversations undetected. Logical fallacies - those logical gaps that invalidate arguments - aren't always easy to spot.
