How to Persuade People

Persuasion is a badly underrated skill. We tend to think it belongs to salespeople, lawyers, and politicians, but in fact everyone persuades every day: persuading the interviewer to hire you, persuading your boss to give you a raise, persuading a client to sign, persuading an investor to put up money, persuading your partner not to work overtime again this weekend. People who can get things done are plentiful, but people who can make others trust you, support you, and act on your behalf are forever scarce.

Interestingly, the best theory of persuasion comes not from a modern business school but from a Greek who lived twenty-three hundred years ago.

The Source of It All: Aristotle’s Three Elements of Persuasion

In Rhetoric, Aristotle proposed that all successful persuasion rests on three pillars: Ethos, Pathos, and Logos. Every popular persuasion framework today—whether the formula for a fundraising pitch or the template for a sales script—is at bottom a different permutation of these three elements.

Ethos: Credibility—“Why should I listen to you?”

Before the other person evaluates what you say, they evaluate who you are. The same sentence—“this stock is going to go up”—carries entirely different weight coming from Warren Buffett versus a taxi driver. Credibility comes from three sources: your identity and credentials (titles, track record, professional background), third-party endorsement (client reviews, references, media coverage), and the expertise and sincerity you display in the exchange itself. Ethos is implicit; it often starts working before you even open your mouth, but it determines whether the other person is willing to hear you out.

Pathos: Emotion—“Did it move me?”

Humans like to think of themselves as rational animals, but neuroscience has shown over and over: people make decisions with emotion first, then use logic to find reasons for the decision. Fear (fear of missing out, fear of loss), desire (longing for a better state), resonance (“you really get my pain”)—these emotions are the true engine of action. A great salesperson jabs at the pain point first; a great pitcher paints the vision first; in essence both are mobilizing Pathos.

Logos: Logic—“Does it hold up?”

Data, reasoning, chains of cause and effect, comparative cases. In modern business persuasion, Evidence, Traction (growth data), and Proof all belong to this layer. But note what Logos actually does: it rarely makes someone act on their own initiative. Its job is to make a person unable to refute you, and to give them a respectable reason to talk themselves into it.

In practice the usual order is: first establish Ethos so the other person is willing to listen; then use Pathos to open the door so they want to keep listening; finally close with Logos to give them a rational step to stand on. None of the three can be missing—logic alone feels cold, emotion alone feels like a con, and credentials alone feel arrogant.

Ten Scenarios: Localized Versions of the Three Elements

Once you grasp this underlying model, look at the specific scenarios. You’ll find that the so-called classic frameworks are just “localized versions” of the three elements for different audiences.

Getting Promoted and a Raise: Claim → Reason → Evidence

Many people pursue a promotion by hinting, waiting, and hoping the boss “notices”—and the result is usually disappointment. The professional approach is exactly the opposite: ask directly and with structure.

Step one, Claim: state clearly what you want. “I’d like to be promoted to senior manager in the next review cycle.” No circling, no fishing. Coming straight to the point actually makes you look professional and self-assured.

Step two, Reason: explain why the request is justified, focusing on the company’s and the boss’s point of view. “Over the past six months I’ve effectively been doing this job already—leading a team of three and owning delivery for two product lines.” The core of the reason is not “I work hard,” but “I’m already creating the value this role corresponds to.”

Step three, Evidence: seal it with facts. Performance data, project results, positive feedback from clients or colleagues. “Those two product lines grew quarterly revenue by 40%, and the renewal rate went from 75% to 90%.”

This structure maps onto Aristotle: the Claim shows self-assurance (Ethos), the Reason is the logic of interests, and the Evidence is pure Logos. A common mistake is to reverse the order—rambling through a list of everything you’ve done and only gingerly raising the request at the end. That leaves the other person confused for the first five minutes about “what are you even trying to say,” and your persuasiveness takes a big hit.

Job Interviews: The STAR Method

The most common interview format is the behavioral question: “Tell me about a hard problem you solved,” “Describe a time you had a conflict with a coworker.” The gold-standard structure for answering these is STAR.

Situation: set the context in a sentence or two. “Two weeks before the project launch, the core backend engineer suddenly quit.” Note: just a sentence or two—many people talk for three minutes here, and the interviewer has already tuned out.

Task: what your responsibility was. “As the project lead, I had to ensure on-time delivery.”

Action: what you specifically did. This is the heart of the whole answer and should take up more than 60% of it. The key technique is to use “I” rather than “we”—the interviewer wants to hire you, not your former team. “I re-prioritized the remaining work by risk, cut two non-core features, took over the payments module myself, and persuaded the next team to lend us an engineer for a week.”

Result: a quantified outcome. “We shipped on time, customer satisfaction that month was 95%, the two cut features were added back in the next release, and we received zero complaints.”

The essence of STAR is to use a real, data-backed story to build Ethos—just saying “I work well under pressure” persuades no one, but a concrete story leads the interviewer to that conclusion on their own. Letting the other person reach the conclusion themselves is always more powerful than telling them outright.

The Elevator Pitch: Win or Lose in 30 Seconds

The premise of the elevator pitch is that you run into a key person in an elevator and have only 30 to 60 seconds to make them interested in you. The structure is four steps: who I am → what problem I solve → how I solve it → a hook.

For example: “I work on cross-border logistics SaaS. Right now, a small or mid-size seller shipping to an overseas warehouse has to switch back and forth between five systems on average, and reconciliation alone eats up one person’s time. We connect the whole flow on a single platform, and 300 sellers are already using it. Your company does cross-border business too, right? Mind if we exchange contact info, and I show you a three-minute demo sometime?”

Note a few details. The pain point has to be specific enough to trigger instant resonance—“five systems” and “one person’s time” are far more vivid than “low efficiency,” a miniature application of Pathos. “300 clients” is one second of Logos. And the most easily overlooked part is the hook at the end: ask for contact info, set up a next meeting, send materials—there must be a clear next step. An elevator pitch with no hook, however brilliantly delivered, is just self-indulgence.

Work Email and Asking for Resources: BLUF

BLUF stands for Bottom Line Up Front, a communication tradition that comes from the U.S. military: conclusion first.

The traditional habit in Chinese writing is “setup—development—conclusion,” building up layer by layer and finally revealing the point at the very end. But in a business email this is a disaster. Studies show busy decision-makers spend an average of 8 seconds on an email. If your request is buried in the third paragraph, it most likely won’t be seen at all.

BLUF flips the whole structure around:

The first sentence states the conclusion and the request directly: “Requesting two additional frontend engineers for the project team, budget roughly X, approval needed by this Friday.”

Only then do you give the reason: “Under the current schedule we have a 40% staffing gap; without reinforcement, the delivery date is projected to slip by three weeks, which would affect the launch milestone committed to the client.”

Finally you attach the evidence: the schedule, the hours breakdown, the risk assessment—as an attachment or link for the other person to consult if needed.

BLUF takes deliberate practice for Chinese speakers because it runs counter to instinct—we always worry that “leading with the ask is too abrupt.” But for a busy person, the greatest respect is precisely not wasting their time.

Fundraising Pitch: Problem → Solution → Traction

Investors see dozens of projects a week, and they have only three questions in mind: is the market big enough? Why you? Is there evidence you’re already making it work? Those map onto the classic three-part fundraising narrative.

Problem: what pain point exists in the market and how big it is. This step should also answer the market size in passing—“China has 40 million small and mid-size merchants, 80% of whom still manage inventory in Excel, generating over a hundred billion in losses every year as a result.” The more concrete and visceral the pain, the stronger the Pathos.

Solution: how your product solves the problem, and why you’re the one who can pull it off. The second half is what matters—team background, technical moats, unique resources. “Our three founders were respectively the heads of product, engineering, and sales at top-tier SaaS companies” is a direct injection of Ethos.

Traction: the part investors care about most, because it proves the first two parts aren’t empty talk. Month-over-month growth, the revenue curve, customer retention, repurchase rate. One beautiful growth curve beats a hundred pages of market analysis. Early-stage projects with no revenue data should still bring out everything they have: seed-user retention, the length of the waitlist, feedback from pilot customers.

What’s special about the fundraising scenario is that investors are inherently skeptical of everything, so Logos (data) carries more weight here than in any other scenario. But the opening Problem still has to be told with Pathos—first make the investor feel the problem is worth solving, and only then will they have the patience to look at your data.

Sales: Pain → Gain → Proof

The sales three-part structure shares the same root as the fundraising one, but the perspective shifts entirely to the customer themselves.

Pain: hit the customer’s pain precisely so they feel “you get me.” “Doesn’t your support team spend half its day answering the same repeated questions?” Note this step is a question, not a statement—get the customer to say “yes, exactly,” and you’re already halfway to persuading them.

Gain: what your solution brings them, quantified in their business language. Don’t say “our product is intelligent”; say “once it’s live it can intercept 60% of repeat inquiries, the equivalent of saving you two support staff in labor cost per month.”

Proof: lower the risk of their decision. Case studies from customers in their own industry are the most effective—“Your peer XX Company used it for three months and cut support response time from 4 hours to 20 minutes.” Pair that with a trial period, results guarantees, and similar mechanisms to dismantle the “but what if it doesn’t work” worry.

There’s a counterintuitive truth in sales: the customer doesn’t care about your product, only about their own problem. So throughout the pitch, the subject should be “you” as much as possible, not “we.”

Public Speaking and Launch Events: The Golden Circle

In his famous TED talk, Simon Sinek introduced the Golden Circle: great communicators all speak from the inside out—Why → How → What—while mediocre ones do exactly the reverse.

Why: your belief and vision. “We believe every small merchant should be able to afford AI.”

How: your distinctive method. “So we spent three years driving deployment cost down to one-tenth of the industry average.”

What: the concrete product. “This is Product X, which we’re launching today.”

The vast majority of people present a product backwards: specs first, then features, with the vision either missing or reduced to a slogan at the end. The audience feels nothing the whole time, because specs can’t move anyone. Steve Jobs unveiling the first iPhone is a textbook case of the Golden Circle: he first said “today, Apple is going to reinvent the phone” (Why), then “we’re combining an iPod, a phone, and an internet device into one” (How), and only then showed the product itself (What).

The Golden Circle is a Pathos-first approach, fit for any occasion that calls for inspiring rather than arguing: product launches, team rallying, brand storytelling. Its power lies in this: people don’t buy what you do, they buy why you do it.

Negotiation: Common Ground, Interests, and BATNA

Negotiation is often misunderstood as “a verbal contest,” but the classic Getting to Yes from the Harvard Negotiation Project offers exactly the opposite mindset: hard on the problem, soft on the people. In practice it breaks into three steps.

Step one: establish common ground first. Don’t open with the disagreement; first confirm a shared goal: “Our goals are aligned—we both want this partnership to last for the long term.” This sentence switches the negotiation from a “you win, I lose” adversarial frame to a “let’s solve the problem together” collaborative one.

Step two: negotiate interests, not positions. A position is “I want 30-day payment terms”; the interest is “I need cash-flow safety.” When both sides expose the real interests behind their positions, a win-win solution often appears—say the other side accepts 30-day terms in exchange for a 2-point concession on price from you. Clinging to positions only produces a standoff; trading interests creates room.

Step three: confidence comes from your BATNA. BATNA (Best Alternative to a Negotiated Agreement) is “your best fallback if the talks fall through.” If you have another offer in hand before a salary negotiation, you naturally stand tall; conversely, if this is your only shot, every “no” you say is a bluff—and the other side can usually sense it. So the real work of negotiation happens outside the negotiation: before you walk in, make your fallback option real.

Copywriting and Marketing: AIDA

AIDA is an advertising framework more than a hundred years old, and it’s still the skeleton of all conversion copy: Attention → Interest → Desire → Action.

Attention: the headline and lead image, life or death in 3 seconds. In an age of information overload, content that isn’t noticed might as well not exist.

Interest: hold the reader with a fact or story that’s personally relevant. “90% of people brush their teeth wrong” works because the reader immediately wants to know whether they’re in that 90%.

Desire: depict the after-state to create “I want that too.” You’re not selling a drill, you’re selling the hole in the wall; not face cream, but the self in the mirror who looks five years younger.

Action: a clear call to action, with the barrier to acting as low as possible. “Click to claim,” “three days only,” “first order free.” Plenty of copy nails the first three steps but ends without a clear call to action, and the traffic drains away for nothing.

Interestingly, livestream shopping is the high-speed loop version of AIDA: the host’s call-out is Attention, the live demo is Interest, “I save half an hour a day using this” is Desire, and “three, two, one, link’s up” is Action—one loop in two minutes, run a few hundred times in a night.

Persuading Family and Partners: Nonviolent Communication

What all the previous scenarios have in common is that the other person shares an interest with you, so talking about interests and data works. But intimate relationships are different—here logic often doesn’t work, and arguing your case can even pour oil on the fire, because what the other person wants is never to be persuaded, but to be understood.

Marshall Rosenberg’s Nonviolent Communication (NVC) offers four steps:

Observation: state only the facts, without smuggling in judgment. Say “you came home after 11 p.m. three nights this week,” not “you never care about the family.” Words like “always” and “never” are judgments that instantly trigger the other person’s defenses.

Feeling: express your own emotion rather than blaming the other person. “When I eat dinner alone, I feel a bit lonely.”

Need: name the need behind the emotion. “I need us to have some real time together each week.”

Request: make a specific, actionable request rather than a vague demand. Say “could we have dinner together this Saturday?” not “can’t you spend more time with me?”

The fundamental difference between NVC and the other frameworks is that here Pathos is not a means but the end itself. Your goal isn’t to “win the argument” but to rebuild the connection. In fact, winning the argument and losing the affection in an intimate relationship is the most total kind of failure.

A Universal Boost: Five Stackable Psychological Levers

Finally, whichever framework you use, you can stack on a few psychological techniques validated by extensive experiments. They come from Robert Cialdini’s classic Influence:

Reciprocity: give first, then ask. A free trial, doing the other person a favor first, sharing a valuable resource—humans have a natural discomfort with “owing a favor” and instinctively want to repay it.

Commitment and consistency: first get the other person to agree to a small request (psychologists call this the “foot-in-the-door effect”), and the probability they’ll agree to a larger request afterward rises significantly, because people have a strong drive to keep their self-image consistent.

Social proof: “all your peers are using it” is far more persuasive than “our product is great.” When uncertain, people decide by reference to how similar people behave.

Scarcity: limited time, limited quantity, exclusive. Loss aversion is one of the strongest human motivators—the drive to avoid losing is about twice as strong as the desire to gain.

Contrast and concession: make a large request first, get refused, then retreat to your real goal (the “door-in-the-face effect”). The other person feels you’ve made a concession and, out of reciprocity, is more likely to agree.

Conclusion: The Framework Is the Map, Sincerity Is the Compass

Looking back over these ten scenarios, you’ll find they never stray from the same root—they all answer the same three questions: what I want (say it clearly), what’s in it for you (talk interests), and why you should believe me (give evidence). This is precisely Aristotle’s three elements echoing two thousand years later.

But one last thing must be said: every framework is only a map, not the destination. The highest level of persuasion is not a pile of techniques but truly believing what you say and truly looking out for the other person’s interests. Technique can get a good proposal heard, but it can’t hold up a bad one; it can amplify sincerity, but it can’t fake it.

First become someone worth believing, then learn how to be believed—that is the complete answer to this ancient art of persuasion.
