You see dozens of ads every day that fail to actually tell you why you might buy the product. Instead, they depict celebrities using it, manufacture false urgency or suggest that everyone else is in on the purchase. These strategies are effective despite being logically wrong, and they waste advertisers billions of dollars on campaigns that erode trust.

According to Kantar’s 2024 Media Reactions study, 58% of consumers say they distrust advertising, with logical fallacies examples in media and emotional manipulation cited as primary reasons. But countless brands still use these tactics because they can drive short-term sales, while also eroding long-term brand equity.
This guide breaks down the most common fallacies in advertising and demonstrates how advancements in marketing technology are more favorable to both brands and consumers.
What Are Fallacies in Advertising?
Fallacies are NOT just mistakes, they are weaknesses in an argument that make the argument appear stronger than it is. In advertising they are inducements and dodges which act on peoples’ emotional, prejudicial or social aversions to sidetrack thinking.
Logical fallacies in ads work by linking messages that feel compelling but don’t hold up under logical scrutiny. They take advantage of cognitive shortcuts that allowed human beings to make quick decisions in prehistoric environments but often cause them to make bad decisions in the modern world.
The key characteristic of advertisements with logical fallacies is that if you take out the logical boo-boo, there’s not really much of an argument for the product. If the only reason to purchase something is because of a celebrity endorsement, and that celebrity has no actual expertise in what they are endorsing, there’s a fallacy behind the ad.
10 Logical Fallacies in the World of Advertising (and How to Spot Them)
These real life examples of fallacies in media are also great examples of how big brands push flawed logic to persuade you to buy.
#1. Bandwagon Appeal
“9 out of 10 dentists recommend” has been a toothpaste tagline for years — from Colgate to Crest. The suggestion is if most dentists say one thing, then that must be the right answer. This overlooks the fact that dentists may recommend several brands, and popularity does not equal superiority. The survey method is often obscure and not fully qualified, but the claim can be compelling for its power to make users worry that they are missing out on what “everyone else” has.
#2. False Dilemma
The McDonald’s “You deserve a break today” ad campaign hinted that you had just two choices: to cook at home (crushing) or, instead, to eat at McDonald’s (liberating). That disregards dozens of other options for dining. This fallacy is a favorite among weight loss advertisements, showing their product versus remaining overweight, without consideration for diet, exercise etc.
#3. Appeal to Authority
This is the category of celebrity endorsements from non-experts. Pepsi’s notorious 2017 ad starring Kendall Jenner — in which the suggestion was that a can of soda could solve social justice problems —and where it uses her fame as an implicit authority on things she knew nothing about? Constants to George Clooney selling Nespresso coffee makers, utilizing his celebrity versus any actual knowledge of making coffee.
#4. Ad Hominem
It’s common in attack ads in political races, but you see it frequently among commercial brands as well. When beverage companies imply that you can only be unsophisticated or uncool when drinking their competitor’s product, they aren’t making a pitch about the product at all. Apple’s“ I’m a Mac, I’m a PC” campaign actually humanized computers and poked fun at PC operators rather than simply trying to explain technical distinction.
#5. Hasty Generalization
“This formula worked for me, so it will work for you” — that’s the law of testimonial advertising” That message is everywhere in infomercials and other testimonials. Diet pills display one person’s success story and insinuate everyone will have the same outcome without accounting for unique metabolism, diet or genetic configuration. These examples of fallacies in the media ignore statistical reality for emotional impact.
#6. Red Herring
This is also a trick that’s used in car commercials that play on lifestyle and/or adventure as opposed to fuel efficiency, safety ratings, or reliability. A truck commercial of someone scaling a mountain is diverting from reality-based inquiries about cargo capacity or the price of a tuneup. The distractions pull focus from what actually should be top of mind when we buy.
#7. Slippery Slope
“If you don’t use our anti-aging cream, it will add decades to your face in mere months” implies that one small decision inexorably transforms into an enormous consequence. They use it in insurance ads when they suggest that failing to buy their product will result in financial disaster, ignoring a spectrum of potential results or other protections.
#8. Appeal to Emotion
Sad music and suffering animals in Sarah McLachlan’s ASPCA commercials made viewers loosen their purse strings. Despite the cause being real, the technique sidestepped any rational consideration of whether that specific organization was doing work in which it made the most sense to donate. Many charity and pharmaceutical ads with fallacies rely entirely on emotional manipulation rather than presenting evidence of effectiveness.
#9. False Cause
“I took this supplement, and then I got a promotion at work” is an example of post hoc ergo propter hoc. When people see advertising for energy drinks, they see images of successful people after having drank them (apparently, if we believe the advertisements, their students capable of benefiting through hard work and skill but this not what is being magicalised by the adverts). This fallacy occurs when commercials compare product use with results, without establishing a cause-and-effect connection.
#10. Straw Man
When organic food brands claim that conventional farming “pumps crops full of chemicals,” they are grossly simplifying how pesticides operate and ignoring regulations governing safety. They go after a caricature of regular agriculture, rather than differences in nutrition or the environment. This enhances their argument by attacking a non existent as described.
These logical fallacies in commercials strive in commercials because while they do not hold up logically, but we are a weak-minded sucker for psychology!
The Problem: Why These Myths Are So Effective
Ads with logical fallacies continue to work because of how human brains evolved to quickly make sense in the world around them using heuristics and emotions, rather than carefully analyzing the underlying logic. Our ancestors who paused to consider each choice were eaten by the predators rationally. Those whose instincts were reasonably well calibrated to the reality of their environment — who leaned on social proof, authority figures and cues from their emotions in order to survive — lived to pass it on.
Time pressure amplifies these effects. When you are scrolling through social media or watching streaming TV, you don’t have minutes to parse the logical structure of each ad. Subconsciously, the fallacy gets logged in and then could affect your next purchase decision, without you actually understanding why.
Repetition compounds the problem. Hearing the same false assertion repeated scores of times, makes it feel like truth by mere dint of familiarity. “9 out of 10 dentists” becomes the truth by virtue of your having heard it all your life.
The economic motivation perpetuates these methods. A brand may understand that its celebrity endorsement doesn’t logically matter, but when it boosts quarterly sales by 5 percent, the pressure is too great for anyone to stop using it. “In the short term, [data-driven metrics] incentivize bull — advertising even when it undermines long-term trust.

The message?
Technology enables ethical advertising when used properly. Depending on how advertisers use the same tools, these can also be used to manipulate or educate.
How Data-Driven Advertising Replaces Logical Fallacies
There are alternatives to fallacy-based persuasion in today’s advertising technology.
- A demand-side platform (DSP) relies on behavioral signals, demographics, and context to target suitable audiences. Someone who is studying baby strollers is going to see ads for strollers, not because “everyone is buying them” but because they’re actively in-market. Relevance obviates the use of fallacy.
- Personalization allows honest value propositions. Instead of writing ads with false dilemmas or celebrities, you can have ads that speak to a particular pain point for that viewer. A parent thinks about safety ratings and storage space. A price-comparison shopper sees prices compared. A tree-hugging type notices sustainable certifications.
- Platforms like the supply-side platform (SSP) meet publisher needs for control over which advertisers appear on their site, vetting misleading claims, and adhering to standards of quality. Given 100% traffic scanning and proven partnerships, the ecosystem self-regulates with more vigor than traditional advertising channels, where anything with a budget could fly.
- The white-label ad exchange puts honest advertisers in front of the right users at scale. Capable of handling billions of operations a second and reacting in 2 ms, the system pairs supply with demand sincerely rather than connivingly.
- Video advertising benefits especially from this shift. The video ad server delivers targeted messages on connected TV and mobile, letting brands tell authentic stories to people who actually care rather than shouting fallacious claims at everyone.

These logical fallacies take advantage of evolutionary psychological habits that make humans gullible to social proof and authority figures and emotional appeals. So they can work to juice short-term sales (while ruining long-term trust) sometimes.

The trade-offs are eroded brand perception as consumers perceive your manipulation, legal fines for false claims, wasted ad spend going after the unqualified masses, reduced coverage efficiency as audiences become jaded, bad buzz on social media and long-term damage to that customer relationship.
How can brands avoid fallacies and create more transparent ads?
Leverage data-driven targeting to target people who could actually benefit from your product instead of trying to trick everyone.

Through programmatic systems, targeting can become so exact that there is no need for tricks.
