You're being manipulated. Right now. Probably by a billboard, a TikTok ad, or maybe even your boss’s latest "we're a family" email. It’s not necessarily malicious, but it is intentional. Aristotle, a guy who lived over 2,000 years ago, basically cracked the code on how humans change each other’s minds, and honestly, we haven't changed that much since ancient Greece. He identified the types of rhetorical appeals—Ethos, Pathos, and Logos—as the pillars of any argument. If you've ever felt a sudden urge to donate to a charity after seeing a sad puppy or bought a skincare product because a dermatologist endorsed it, you’ve been on the receiving end of these modes of persuasion.
Most people think persuasion is just about having the best facts. It isn't. Facts are boring. Humans are messy, emotional, and skeptical creatures. To actually move someone to action, you have to hit them from multiple angles. It's a balance.

The Authority Trap: Ethos and Why We Listen
Ethos is all about credibility. It’s the "why should I care what you say?" factor. If I try to give you medical advice, you should probably ignore me because I’m a writer, not a doctor. But if Dr. Anthony Fauci or a Mayo Clinic researcher says it? You listen. That’s Ethos in action.
It isn't just about degrees on a wall, though. It's also about character. We trust people who seem like they have their lives together or who share our values. Brands do this constantly by hiring "relatable" influencers. They’re borrowing that person’s Ethos to sell you a lifestyle. Think about Patagonia. They don't just sell jackets; they sell a commitment to the environment. Their Ethos is built on decades of actual activism, which is why people are willing to pay $300 for a fleece they could get at Target for $40.
But here is where it gets tricky: Ethos can be faked. Ever seen a commercial where an actor wears a white lab coat? That’s "borrowed interest" Ethos. They aren’t experts, but the visual cue of the coat triggers a psychological response that says "this person is trustworthy." It’s a bit of a shortcut, and it works scarily well on the subconscious level.
The Heartstring Tug: Pathos is the Real Mover
Pathos is the heavy hitter. It’s the appeal to emotion. Honestly, most of our decisions are emotional ones that we later justify with logic. It’s the "gut feeling." When a political ad uses dark, grainy footage and ominous music, that’s Pathos. They want you to feel fear. When a Thai life insurance commercial makes you weep over a father’s sacrifice, that’s Pathos too. They want you to feel love and a sense of duty.
Aristotle knew that an audience in a state of anger or joy is much easier to persuade than one that is indifferent. Indifference is the enemy of persuasion.
Consider the "I’m a Mac / I’m a PC" ads from the mid-2000s. They didn’t list technical specs. They didn't talk about RAM or processing speeds. Instead, they made you feel something about the brands. The Mac was cool, relaxed, and creative. The PC was stuffy, prone to sneezing (viruses), and awkward. You didn't buy a Mac because the math was better; you bought it because you wanted to feel like the cool guy in the hoodie.
- Fear: "If you don't use this security system, your family is at risk."
- Pity: The classic SPCA commercials with Sarah McLachlan.
- Pride: "Because you deserve the best."
- Empathy: Sharing a personal story of struggle to connect with an audience.
Too much Pathos feels manipulative, though. We’ve all seen those LinkedIn posts that feel like "trauma dumping" for engagement. If you lean too hard into the emotion without any substance, people eventually get "compassion fatigue" and tune you out.
The Hard Math: Why Logos Still Matters
Logos is the appeal to logic. This is where you bring out the charts, the data, the "if-then" statements. It’s the most straightforward of the types of rhetorical appeals, but it’s often the weakest on its own.
Think about climate change. Scientists have had the "Logos" side of the argument won for decades. The data is mountainous. The logic is sound. Yet, global action has been slow. Why? Because Logos doesn't get people out of bed in the morning. Pathos does.
However, you need Logos to seal the deal. In a B2B business setting, you might win a CEO over with a vision (Pathos) and your reputation (Ethos), but the CFO is going to demand the Logos. They want to see the ROI. They want to see the spreadsheet.
Effective Logos uses:
- Deductive Reasoning: Starting with a general truth and moving to a specific conclusion ($A = B, B = C, therefore A = C$).
- Inductive Reasoning: Taking specific examples and drawing a broad conclusion.
- Syllogisms: "All humans are mortal. Socrates is a human. Therefore, Socrates is mortal."
In modern marketing, Logos looks like "Kills 99.9% of germs" or "Save 15% or more on car insurance." It gives the brain a "fact" to latch onto so it can feel smart about a decision that was probably influenced by the other two appeals.
Kairos: The Secret Ingredient Nobody Talks About
While Ethos, Pathos, and Logos are the "Big Three," there’s a fourth one called Kairos. It means "the right time." You can have the best argument in the world, but if you deliver it at the wrong moment, it’s dead on arrival.

Selling umbrellas is easy when it’s raining. That’s Kairos. Trying to sell a luxury cruise during a global financial meltdown? Bad Kairos. In communication, Kairos is about reading the room. It’s why brands sometimes get "canceled" for posting a tone-deaf tweet during a national crisis. They ignored the rhetorical timing.
Putting the Pieces Together
The most effective communication uses a "Rhetorical Triangle." It’s the sweet spot where all these elements overlap.
Imagine you’re trying to get a raise.
If you only use Pathos ("I’m really stressed about my rent"), your boss might feel bad, but they might also think you’re unprofessional.
If you only use Logos ("I’ve increased output by 20%"), they might agree but tell you there’s no budget.
If you only use Ethos ("I’ve been here five years and I’m a loyal employee"), they might say "thanks for your service" and leave it at that.
But if you combine them? "I’ve been a dedicated lead here for five years (Ethos), and in that time, I’ve personally brought in $200k in new revenue (Logos). I’m incredibly passionate about where this company is going, and I want to make sure my role here is sustainable for my future (Pathos)."
That is much harder to say no to.
Common Pitfalls in Persuasion
A lot of people think they’re being logical when they’re actually just being loud. Or they think they’re being empathetic when they’re actually being patronizing.
One major mistake is the "Logical Fallacy." This is when you use something that sounds like Logos but is actually broken. The "Straw Man" argument—where you misrepresent someone’s point to make it easier to attack—is a classic. Another is the "Ad Hominem," where you attack the person’s character (Ethos) instead of their argument. We see this in political debates constantly. Instead of discussing policy, candidates talk about each other's past mistakes. It’s effective for swaying an audience, but it’s intellectually dishonest.
How to Use This Tomorrow
You don't need a PhD in rhetoric to use this. Just start noticing it.
When you’re writing an email, ask yourself: "Am I giving them a reason to trust me (Ethos)? Am I giving them a logical 'why' (Logos)? Am I connecting with what they actually care about (Pathos)?"
If you're a business owner, look at your website. Is it all Logos (boring features list)? Add some Ethos (testimonials) and Pathos (the "problem" your customer is suffering through).

The goal isn't to be a master manipulator. It’s to be a better communicator. When you understand the types of rhetorical appeals, you stop shouting into the void and start actually being heard.
Next Steps for Mastery:
- Audit your own content: Take your last three social media posts or professional emails. Identify which appeal you leaned on most. If you didn't use all three, try rewriting one to include the missing piece.
- Analyze a commercial: Watch the next ad you see on YouTube. Note the exact second they switch from Pathos (the story) to Logos (the product features).
- Practice Kairos: Before your next big ask, wait for a moment of "green light" energy—like right after a successful project launch—rather than forcing the conversation.
