Bad Arguments and Bogus Logic: Navigating Logical Fallacies

Navigating Logical Fallacies - Generic Illustration

Have you ever found yourself in a heated argument where you do not seem to be getting anywhere? Where neither side is listening and you keep attacking "straw man" versions of each other's points?

Logical fallacies have fascinated me because they deal with the very foundations of how we think and communicate ideas. Yet it is remarkably easy to slip into fallacious arguments without realizing it. I certainly know I have been guilty of faulty logic many times before!

I do not claim to be an expert, but I hope this overview provides some helpful perspective. Let's dive in!


1. Straw Man

The straw man fallacy gets its name from creating a figurative "straw man" — a weak, brainless scarecrow that is easy to knock down. The straw man fallacy involves misrepresenting someone's argument or position to make it easier to attack. For instance:

Person A: You really should not make straw man arguments.
Person B: Oh well, then I guess we should just not have arguments at all!

This flawed reasoning pattern distracts from the original idea by substituting in and attacking an altered version. It is like loudly arguing with an imaginary opponent, which does little to persuade the actual person in front of you.

The straw man is considered a subtype of another fallacy called the "red herring." A red herring refers to any irrelevant distraction used to divert attention from the original point. So straw men fall under this umbrella by shifting focus to a distorted tangent.


2. Begging the Question

"Begging the question" refers to an argument where the conclusion simply restates the premise. This provides no factual support since the reasoning moves in a pointless circle.

For example, a common begging-the-question argument during the Cold War was, "The United States is the world's greatest democracy. Therefore, all of our actions reflect democratic values." This bases the conclusion that US actions are democratic solely on the unproven premise that the US exemplifies democracy. Rhetorical declarations about America's democracy do nothing to demonstrate that any specific policies are democratic. Yet this format crops up repeatedly in political discourse to "support" partisan points.

Begging the question demonstrates muddled, circular thinking. It fails to substantiate assertions with logic and instead appeals to claims as questionable as what is being argued for.


3. Slippery Slope

The slippery slope fallacy claims that taking one step will inevitably lead to extreme consequences further down the metaphorical line. This constitutes flawed deductive reasoning by presuming a cascade effect without justification.

For example, arguing that allowing minor government surveillance will eventually put cameras in all homes is a slippery slope argument. There is no logic showing why small laws would make a total loss of privacy inevitable.

The slippery slope is also called the "camel's nose." Like a camel nudging its nose into a tent and eventually bringing in its whole body, the fallacy claims the first minor step makes subsequent ones unavoidable. But this ignores the possibility of halting the process.

Watch for absolutes like "will definitely lead to" without supporting chains of reasoning. Just because one thing might influence another does not mean extreme outcomes are unavoidable. Real-world results often depend on mitigating actions too. Like trying to stand still on actual slippery slopes, assuming worst-case slides often leads to irrational conclusions.


4. False Cause

The false cause fallacy asserts improper cause-and-effect relationships without justification. An example is blaming increased violence on media like video games. While exposure may correlate with aggression, other factors like mental health, home life, and personality likely play roles. False cause arguments oversimplify by declaring a single influence as the definitive cause.

A class of false cause fallacies is called Post Hoc Ergo Propter Hoc, meaning "after this, therefore because of this." This claims Event A caused Event B simply because A preceded B. Correlation does not prove causation. Superstitions are general examples of this type.


5. Appealing to Popularity

Appealing to popularity, or Argumentum ad populum, claims an idea is true or right because it is popular. Three main tactics emerge:

  • Bandwagoning: asserting "everybody is doing it." Popular behavior does not necessarily equal wise behavior. Otherwise we would still think the earth is flat when people believed so.
  • Patriotic approach: stirring feelings with words like "patriotism." Wrapping arguments in flags does not address their merits.
  • Snob approach: claiming "all the best people do it." This subtly attacks dissenters rather than proving the argument. Even intelligent people can be mistaken or disagree.

Beware notions assumed true or ethical simply because they garner widespread or elite support. The flaws, hypocrisies, and mistakes of the majority recur throughout history. An idea must stand on its own merits, not on its popularity.


The Bottom Line

Logical fallacies litter debates, advertisements, and everyday chatter. How can we catch them and steer around flawed reasoning?

Maintaining critical thinking helps identify poor arguments. Watch for unsupported sweeping claims. Question suspect assumptions and emotional appeals. Analyze whether premises truly prove conclusions. Entertain counterarguments charitably. Consider multiple perspectives since truth resists simplicity. Present substantive evidence, not just assertions.

Of course, we all fall victim to flawed reasoning at times. Catching fallacies requires constant vigilance, patience, and charitable interpretation. Particularly, identifying and avoiding faulty logic can strengthen discussions and decisions. With care, we can navigate the minefield and find common ground.
