How to Use Psychology in Writing: 12 Rules

Written by Leandre Larouche | May 21, 2024 12:00:00 PM

Most people think writing is about language.

They obsess over sentence structure, grammar, and finding the “right” words. But those are just surface tools—what truly drives compelling writing is psychology. Human behavior, not perfect phrasing, is what pulls readers in and keeps them turning the page.

This might sound controversial, especially if you've studied literature or creative writing. I get it. I studied English literature and professional writing myself. I wrote my first book during university. And while my education gave me a strong foundation in writing style and structure, it didn’t teach me what I later learned through experience: people don’t respond to writing because it’s elegant. They respond because it connects with their psychology.

After writing and editing over 15 million words—and helping more than 130 clients write books, blogs, and content—I’ve come to see one truth repeated over and over: what makes writing powerful is its ability to influence the mind, not decorate the page.

In this article, I’ll share 12 psychological principles that will elevate your writing, whether you're crafting research papers, building a brand, or writing a nonfiction book. These aren’t theories pulled from a textbook. They’re patterns I’ve observed through years of working in the trenches as a ghostwriter and coach.

If you want your content to resonate, convert, and endure—understand the brain behind the reader. Let’s look at how psychology in writing makes all the difference.

1. People Are Desensitized: Start with Emotion That Cuts Through Noise

Modern readers are overstimulated. They scroll past headlines, skim intros, and skip entire paragraphs. Most writing dies before the first sentence is done.

That’s why emotional resonance isn’t optional—it’s the entry point. If your writing doesn’t stir something in your reader within seconds, they’ll click away.

As a ghostwriter and coach, I’ve seen this play out across industries. The most effective openings don’t start with information—they start with sensation. Whether it’s a heart-wrenching anecdote, a shocking image, or a single emotionally loaded word, the goal is the same: interrupt the reader’s default state.

Potent emotion hooks attention. Once you have it, you can do anything.

This rule applies to all writing—web content, books, blog posts, even research papers. If you want engagement, lead with feeling.

This is also a natural place to connect to foundational writing skills. For a deeper dive into building emotional connection from the first sentence, you can look at How to Improve Your Writing Skill.

2. People Are Emotional: Tell Stories, Not Statistics

People process numbers with their heads. But they process stories with their hearts.

That’s why a narrative about a single struggling student will always resonate more than data about school dropout rates. It’s why personal case studies outperform academic research in blog posts—unless the research is wrapped in human terms.

This principle applies even in formal contexts. I’ve edited white papers, research proposals, and even psychology papers where the emotional framing made the work exponentially more impactful.

Stories create meaning. They build trust. They humanize your writing.

Statistics should support your argument, not carry it. Always lead with the emotional core—then let the data prove the point.

3. People Are Naturally Optimistic: Inspire Through Your Own Journey

Humans look for hope. We want to believe things can improve. That’s why transformation stories perform so well—they offer a mirror and a roadmap.

But the key to using this rule is vulnerability. Glossy success stories without friction feel fake. You have to show what it cost.

In my own case, I went from struggling student to writing coach, ghostwriter, and author. But what made that journey real for my audience was the detours, the missteps, the time I almost gave up. That’s where people relate—and that’s what makes your growth feel possible to them.

When writing content, don't just teach. Inspire. Show what your life looked like before the win. Then walk the reader through your choices. This is especially powerful when you're writing blog articles or nonfiction chapters aimed at professionals or entrepreneurs. It also happens to be a core strategy in writing a book to grow your business.

If you want your audience to believe in themselves, show them how you believed in yourself—when it wasn't easy.

4. People Enjoy Living Vicariously: Give Readers a Lens into Another Life

Writing is a form of mental transportation. When it’s done right, readers get to escape their reality and enter someone else’s.

That’s one of the reasons I often share personal experiences from working with clients, living abroad, or navigating the publishing world. For readers, these glimpses into unfamiliar territory don’t just entertain—they create curiosity and admiration.

It’s human behavior. We enjoy watching someone walk a path we haven’t taken, whether it’s launching a business, ghostwriting a bestseller, or simply living with intentional discipline.

This technique is especially powerful when your audience aspires to what you’ve already done. It makes your writing aspirational without becoming arrogant. You’re not just telling them what’s possible—you’re showing them you’ve lived it.

And that builds immediate credibility.

5. People Love Comparison: Share Your Failures to Build Trust

One of the fastest ways to lose a reader’s trust is to pretend you’ve never failed.

That’s why I make it a point to share my early missteps—clients I lost, projects that collapsed, and lessons that cost me time and energy. These aren’t low points to hide. They’re connection points. They make you human.

Readers naturally compare themselves to others. When they see someone ahead of them sharing their struggles, it creates psychological safety. They think, If he went through that and still succeeded, maybe I can too.

This doesn’t mean you turn your content into a confessional. But strategic use of failure—anchored in growth—can do more to position your authority than any list of credentials.

In fact, one of the most effective author bios I’ve ever written for a client began not with their achievements, but with their early career doubts. It made the wins feel earned.

6. People Interpret Words Literally: Choose With Surgical Precision

Words are not neutral. Every word you choose carries both a literal meaning and an emotional charge.

This is one of the most overlooked principles in writing. I’ve coached clients who unknowingly weaken their own message by using language that’s technically correct—but emotionally off-key.

For example, saying “I don’t want you to fail” is not the same as “I want you to succeed.” They point to the same outcome, but they do very different things in the reader’s mind.

That’s why great writing isn’t just clear—it’s intentional. It respects both the denotation and the connotation. In marketing copy, this principle determines whether your message inspires action or indifference. In academic writing, it shapes the tone of your argument. Even in student papers or literature reviews, precision adds weight.

One of the best ways to improve your writing style is to audit your language for tone. Are your words reinforcing your message—or accidentally undercutting it?

I’ve had entire paragraphs transform simply by swapping a few key terms.

7. People Have a Negativity Bias: Frame the Risk Before the Reward

As much as we want to lead with inspiration, fear often works faster.

This isn’t manipulative—it’s evolutionary. The human brain is wired to notice threats before opportunities. That’s why headlines warning of loss or danger perform better than those promoting gain. It’s why “Don’t Make These Mistakes” usually outperforms “Do This to Succeed.”

When I work with clients on books or content strategies, we often discuss the ethical use of fear. The goal isn’t to scare people—it’s to wake them up. You don’t need to be a fearmonger, but you do need to understand that people respond more urgently when they sense a risk of pain, embarrassment, or loss.

This applies whether you're writing persuasive web copy or guiding readers through research findings. The warning often opens the door for the solution.

Use fear sparingly, but don’t ignore its power. It's one of the most effective tools in the psychological writing toolkit—especially when balanced with a clear, hopeful resolution.

8. People Are Easy to Intrigue: Open Loops Keep Them Reading

Curiosity is a psychological itch. Once triggered, it begs to be scratched.

This is why open loops—unanswered questions or unresolved moments—are so powerful. They compel readers to stay engaged until they reach closure. It’s how novels work, and it’s how effective nonfiction content holds attention.

Years ago, I stumbled on a show called Startup. I didn’t mean to binge it, but the first scene raised just enough tension and curiosity that I had to keep watching. The same principle applies to writing: if you hint at a problem but delay the solution, you create magnetic tension.

Start your piece with an unresolved anecdote. Ask a provocative question. Interrupt a narrative halfway through, then resume it later. These structural choices aren’t tricks—they’re examples of writing in psychology at its best.

In a world of endless scrolling, open loops are what keep people from bouncing.

9. People Can Only Take Small Cognitive Loads: Structure With Simplicity

Overload kills clarity. It also kills retention.

The average reader can only juggle a few ideas at a time. That’s why grouping content into three, five, or seven points works so well. These are cognitive thresholds that make content digestible and memorable.

This article is a good example. I had twelve points to make. Rather than dump them into a single block, I structured them in four parts—each with a theme, rhythm, and clear break.

This rule is especially important in research papers, scientific writing, and business content. If you overwhelm readers with too much information too quickly, they disengage. Worse, they forget what they just read.

Clarity isn’t about dumbing down. It’s about respecting the mental bandwidth of your audience. Strong writing isn’t about how much you say—it’s about how well what you say sticks.

10. People Trust What They Understand: Use Simpler Words

There’s a myth among inexperienced writers that complexity equals intelligence. But if you’ve spent any time writing for actual people—clients, students, readers—you know the opposite is true.

Complicated writing doesn’t build trust. It confuses readers and makes you sound insecure. Simplicity is what communicates confidence.

In academia, I was taught to use long, abstract phrases and specialized vocabulary. That style may work in scholarly journals, but in the real world—where clarity matters more than prestige—it falls apart. Whether you're writing a book, a blog, or a research proposal, the goal is the same: communicate ideas in a way that readers can instantly grasp.

Using simple words doesn’t mean oversimplifying concepts. It means choosing language that allows your audience to access those concepts without friction. That’s how real authority sounds.

If you want people to listen, write the way they think.

11. People Feel Better When They Laugh: Use Humor to Humanize

Humor builds connection faster than any other tool in your writing arsenal. It lowers defenses, increases likability, and makes your content more memorable.

But like anything powerful, it requires finesse.

Humor is deeply contextual. What lands with one audience might fall flat with another. And if you’re writing for an international or professional readership, misfired humor can damage your credibility.

Still, I’d argue it’s worth the risk.

I’ve used humor in psychology writing, client projects, and even ghostwritten books for leadership experts. When done with tact, it adds tone and rhythm. It gives your writing a pulse. Even a subtle self-deprecating comment or a clever turn of phrase can make a piece more enjoyable to read—and that’s often enough to keep readers going.

If you’re not sure what kind of humor fits your brand, start with personal examples. These tend to be relatable and low-risk. And if a joke misses? Readers forget quickly.

The upside is worth it.

12. People Forget Easily: Repeat What Matters

Repetition is not a flaw in writing. It’s a function of how human memory works.

I used to believe that saying something once was enough—that readers would catch the message the first time. They don’t. Most skim. Many forget. And unless you strategically reinforce your key points, your message fades.

In psychology papers and scientific writing, repetition is used to reinforce claims. In marketing copy, it’s used to drive action. In nonfiction books, it helps organize a reader’s thinking across chapters.

The same holds true in your writing.

To be remembered, say it more than once. But don’t just repeat your words—repeat your core ideas in different forms. Use examples, metaphors, summaries, and callbacks. Repetition done well feels like rhythm, not redundancy.

The best writing doesn’t rely on memory. It builds it.

Writing Isn’t About Words—It’s About Psychology

If you want to improve your writing style, don’t just study grammar or sentence structure. Study people.

The most persuasive, memorable, and impactful writing taps directly into human behavior. It bypasses intellect and speaks to instinct. This is true whether you're working on blog content, writing a nonfiction book, or preparing research proposals.

That’s why these twelve psychological principles matter so much. They remind us that writing isn’t just a skill—it’s a form of influence. And when you understand how people think, feel, and make decisions, your writing becomes sharper, deeper, and more effective.

Language is the surface. Psychology is the engine.
