The Real Reason Introverts Might Struggle to Find the Right Words
Introverts often find it hard to express their thoughts quickly, but that’s not a flaw. It’s their brains doing what they do best — diving deep.
Suddenly, a coworker appears at my desk and asks me a question. The look in her eyes and the urgency in her voice tell me she wants an answer now. Her question is simple, but my brain freezes. I start sentences, then stop. I hesitate. I say things that are almost what I mean, but not quite. I backtrack. My coworker — an extrovert who seems to express herself effortlessly — gives me a look that says, Hurry up and spit it out! Inside, I’m silently pleading: Why can’t my brain just work right?
Ever had something like this happen to you? If so, you’re not alone. Struggling to find the right words — especially when you’re put on the spot — is a common experience for many introverts. And there are good reasons this happens… ones you might not expect.
The Challenge of Word Retrieval
The struggle to find the right word when you need it is called word retrieval. It’s that frustrating moment when a familiar word is suddenly out of reach — even if you use it all the time. It’s like digging through a giant toy box for a specific toy. You know exactly what it looks like, but you still have to rummage through everything else to find it.
Everyone has moments like this, but word retrieval can be especially tricky for introverts because we process information deeply. We chew on ideas, turning them over and looking at them from every angle. And when you’re thinking deeply — even about something as simple as what to make for dinner — it can be hard to shift gears and speak. Unlike extroverts, many introverts don’t “think out loud.” We process things inwardly. Quietly. Often without words.
That’s why, when we struggle with word retrieval, we might not be able to keep up with fast-talking extroverts. At work, people might mistakenly assume we’re unsure of ourselves, even when we know exactly what we’re talking about. In school, we might hesitate to raise our hand because it’s hard to put our thoughts into words on the spot.
The Role of Long-Term Memory
In her book The Introvert Advantage, Dr. Marti Olsen Laney offers another explanation for why introverts sometimes struggle to find the right words. It may have to do with how we use our long-term memory.
As the name suggests, long-term memory stores information for a long time — possibly forever. But most of that information lives outside our conscious awareness, so accessing it isn’t always easy. For example, try remembering your first day of kindergarten. Some details might pop into your mind right away, but others take a little more effort to recall.
In contrast, working memory (also called short-term memory) is where we hold information for just a few seconds. It’s easily accessible, but unless we intentionally move that information into long-term storage, it quickly fades away.
Interestingly, Laney notes that introverts tend to rely more on long-term memory, while extroverts more often use their working memory. That means extroverts are more likely to have information “on the tip of their tongue,” ready to go. For introverts, though, it may be buried a little deeper.
The challenge is that digging through long-term memory takes time. You need the right “key” to unlock what you’re trying to recall. For instance, seeing a specific pair of sneakers (the key) might remind you of your own childhood shoes — then of the milk that spilled on them — then of your first day of kindergarten. One memory leads to another, like a chain reaction.
But all that searching and linking takes time. And when you’re in a conversation, that delay can make it harder to respond quickly — something many introverts experience.
How Anxiety Affects Introverts’ Ability to Speak
When we’re nervous while trying to talk — like I was when that intimidating coworker approached me — it can make finding and saying the right words even harder. Not all introverts feel anxious in social situations, but many of us do feel a bit uneasy. That’s because we tend to think things through deeply (sometimes we overthink), and being around people can drain our energy — cue the infamous introvert hangover. With all that going on, it’s easy for anxiety to sneak in.
Anxiety doesn’t just make you feel jittery or uncomfortable; it can also wear out your brain and mess with your memory. When you’re anxious, your body releases a stress hormone called cortisol. Cortisol plays an important role in many body functions: It helps regulate your sleep/wake cycle, raises your blood sugar when needed, gives you quick bursts of energy, and even helps form memories.
But here’s the problem: Too much cortisol, especially from ongoing stress or anxiety, can backfire. When stress becomes chronic, excess cortisol can make it harder to remember things. In fact, research shows that chronic stress can actually change the structure of your brain, including areas like the hippocampus, which is crucial for learning and memory.
So for introverts, anxiety adds another layer of difficulty. Not only does it make it harder to speak in the moment, but over time, unmanaged stress can affect how your brain functions, making it even tougher to retrieve the right words when you need them.
Why Introverts Prefer Writing
In her groundbreaking book Quiet, Susan Cain points out that introverts “often feel as if they express themselves better in writing than in conversation.” And she’s right, because it’s not uncommon to find introverts among professional writers. Bestselling author John Green (The Fault in Our Stars) once described writing as a solitary activity that suits introverts perfectly: people who “want to tell you a story but don’t want to make eye contact while doing it.”
But it’s not just about writing novels. Many introverts prefer to text or email instead of calling or meeting face-to-face. Others turn to journaling as a way to process their thoughts and emotions more clearly.
So, why does writing often feel easier than talking for introverts? According to Dr. Marti Olsen Laney, it has to do with how our brains work. Speaking and writing use different brain pathways, and the ones used for writing tend to function more smoothly for introverts. Writing gives us time to think, reflect, and choose our words carefully — all things that come naturally to the introverted mind.
What to Do When Your Mind Goes Blank
Memory is a complicated process. Your brain stores information in different areas and builds connections between them. As mentioned earlier, you need the right “key” to unlock something from long-term memory. The good news? Most memories are stored with multiple associations, so if you can find just one key, the rest often follows. As Dr. Marti Olsen Laney puts it, “If we find just one key, we can retrieve the whole memory.”
If you’re struggling to remember a word, a fact, or even something simple — like what you did over the weekend (a favorite small talk topic) — try these steps:
- Be still and relax. Give yourself permission to pause. Don’t let the other person’s energy pressure you to respond right away.
- Buy yourself time. Say something like, “Let me think about that…” or “Hmm, give me a second.” You can also give a nonverbal cue that you’re thinking, like looking away or furrowing your brow.
- Let your mind wander. Follow your thoughts wherever they go. One idea might lead to another, and eventually help you retrieve the information you’re looking for.
- Don’t beat yourself up. If the words still don’t come, try not to feel embarrassed. Your brain is doing what it’s wired to do — slow down, process, and think. Quiet moments don’t mean something’s wrong; they’re just part of how deep thinkers operate.
If the silence feels awkward, try making a light joke about being lost for words. Or let the person know you’re thinking it over and will follow up later by email, text, or when you’ve had a moment to gather your thoughts.
Remember: Just because you’re quiet doesn’t mean your mind is empty. Like Stephen Hawking once said, “Quiet people have the loudest minds.”
