Why Fiction Writers Need to Know Psychology

Writing fiction is more than just weaving words together; it's about bringing characters, emotions, and conflicts to life. This is why a fiction writer needs to understand psychology—the study of the human mind and behavior. To create authentic characters, a writer must get into the psyche of those characters, understanding their motivations, desires, and fears. Let’s explore how an understanding of psychology can elevate fiction writing and why it’s essential for fiction writers to know psychology.

Writing: Thinking on Paper

When you write, especially fiction, you're not just putting down words; you're essentially thinking on paper. This process involves considering how your characters think, feel, and act in different situations.

You have to become your character, which means you cannot be yourself.

To make your story and characters believable, understanding how people think becomes crucial. This is where psychology comes into play.

Fiction writers who possess a deep understanding of psychology are better equipped to create layered characters that readers can relate to. Every action and dialogue needs to resonate with the character's internal world—their mental and emotional landscape. There’s so much more that goes on in the subconscious mind than what the character knows. Fortunately, as the author, you should know exactly what’s going on behind the scenes and portray bits and pieces of that to the audience. In the end, the characters may discover what the author already knows about them. This is the point of revelation for the character that can be quite exciting for the reader.

Readers might not always be able to articulate why a character feels "real" or "alive," but it will be because you've successfully mirrored human psychology in the way they behave on the page.

Think Like a Psychologist: Observe the World Around You

One of the keys to understanding psychology is to develop the habit of observing the people around you. Psychologists excel at studying human behavior, and as a writer, you must do the same to make your character and stories more realistic.

Observing the world and people around you is one of the most practical and effective ways to develop an intuitive understanding of the human psyche.

• Behavior and Dialogue: Watch how people interact. Pay attention to body language, tone of voice, and the unspoken communication that happens between individuals. How do these behaviors shift in different emotional states or social settings?
• Motivations: Ask yourself, why do people act the way they do? What are their deeper motivations, beyond surface-level desires? A good writer digs beneath a character’s words and actions to explore what drives them internally—fear, love, ambition, jealousy, or insecurity.
• Conflict: Psychological conflict is at the heart of compelling fiction. By observing the emotional and psychological struggles of real people, you can translate that into your stories. Whether it’s internal conflict (a character battling guilt or self-doubt) or external conflict (a power struggle between two individuals), the tension will only feel real if it mirrors genuine human psychology.

Reading About Psychology: A Fiction Writer’s Goldmine

Beyond observation, one of the best ways for fiction writers to deepen their understanding of the human psyche is by reading psychology books. While reading fiction helps you learn structure, pacing, and style, reading about psychology offers insights into how the mind works.

• Books on Human Behavior: Dive into works by Carl Jung, Sigmund Freud, or more modern authors like Daniel Kahneman ("Thinking, Fast and Slow") and Robert Greene (“The Laws of Human Nature). These authors can provide a better understanding of cognitive biases, personality development, and the subconscious forces that influence human decision-making. This knowledge is invaluable when crafting complex, realistic characters.
• Understanding Archetypes: Carl Jung’s work on psychological archetypes can help writers develop characters that resonate on a deeper, universal level. Archetypes like the Hero, the Mentor, the Rebel, or the Innocent speak to shared human experiences and desires. Writers can use these archetypes to anchor characters while adding unique traits that differentiate them.
• Emotional and Cognitive Development: Writers can also benefit from understanding the psychological stages of development. Erik Erikson’s stages of psychosocial development or Jean Piaget’s stages of cognitive development, for example, provide insight into how people grow, change, and think at different stages of life. Whether you're writing a child, an adolescent, or an elderly character, these theories can guide how you shape their thought processes and behavior.

The Limits of Reading Fiction Alone

Many aspiring writers believe that they can learn everything they need about character development and psychology simply by reading fiction. However, while fiction can teach you a lot about writing style, structure, and plot, it’s often lacking in deep, actionable insights into the human mind. That’s why I’ve mentioned the points from earlier. The most potent of all is real-world observation as you can see, first-hand, how other people act.

Writers who only read fiction often risk creating characters that feel shallow or stereotypical because they are drawing from surface-level tropes rather than genuine psychological understanding. Fiction usually follows familiar formulas, and unless you're consciously studying the psychology of the characters, you may fall into the trap of being too cliche or formulaic.

How Reading Fiction Still Helps: Structure and Style

That said, fiction is still important for developing your craft, particularly in terms of structure and style. By reading a wide range of novels, you'll learn how successful authors create tension, pace their stories, and structure their narratives.

You can also see how other authors develop characters, particularly in how they balance internal psychological exploration with external action. Writers like Dostoevsky, and Virginia Woolf, and contemporary authors like Haruki Murakami are masterful at marrying psychology with compelling narratives.

• Pacing Psychological Unfolding: In great fiction, characters don’t reveal everything about themselves all at once. Their psychology is revealed gradually, through actions, inner monologues, and how they react to the events of the plot. Learning this balance—how to drip-feed psychological insights into your character without overwhelming the reader—can be honed by reading fiction with a focus on character development.

Bridging the Gap: Psychology and Storytelling

Ultimately, fiction writers need to bridge the gap between the structural insights gained from reading fiction and the deep psychological insights gained from studying psychology. By doing both, you’ll craft stories that are not only structurally sound but also emotionally and psychologically resonant.

• Empathy: Understanding psychology fosters empathy, both in the writer and the reader. A well-crafted character allows readers to see the world from another’s perspective, even if that character is completely unlike themselves.
• Relatable Characters: At the end of the day, readers are drawn to stories that make them feel something. The more accurately and deeply you can portray the psychology and universal struggles or flaws of your characters, the more your readers will connect with them as all people struggle and have flaws. It is what it means to be human.

Conclusion: Become a Psychological Observer and Storyteller

In the end, fiction writers must become students of the human mind. By observing people in real life, reading about psychology, and honing your skills through fiction, you will be able to create characters that leap off the page and into the hearts and minds of your readers. The journey to mastering character development isn’t easy, but by adopting a psychologist’s lens, you’ll open up new dimensions in your writing.

If you're ready to take your characters to the next level, start by expanding your psychological toolkit. You’ll be amazed at how much richer your stories become when you understand not just how to write but how to think like a psychologist.
