Ever been trapped in a conversation where you couldn't get a word in edgewise? It’s exhausting. You’re standing there, nodding, eyes glazing over, wondering if they even realize you’re a human being and not just a sentient coat rack. We’ve all wondered why do people talk so much at one point or another. Honestly, it’s rarely because they’re trying to be rude. Most of the time, the "over-talker" is stuck in a neurochemical loop or a psychological habit they don’t even see.
Talking is a drug. Seriously. When we talk about ourselves, our brains trigger the same reward centers associated with food or money.

Scientists at Harvard University actually proved this. Researchers Diana Tamir and Jason Mitchell used fMRI scans to see what happened when people shared information about themselves. They found that self-disclosure fires up the mesolimbic dopamine system. That’s the same "feel-good" pathway that lights up when you eat a gourmet burger or win a bet. For some people, that dopamine hit is just too addictive to stop. They aren't just sharing an anecdote; they're getting a high.
The Science of the "Talking High"
It’s not just about ego. Some people are literally wired to be "talkaholics." In the late 1980s, researchers James McCroskey and Virginia Richmond coined the term "Talkaholism" to describe people who just cannot stop. These aren't just chatty folks. They are compulsively communicative.
Think about your friend who narrates their entire day.
They tell you what they had for breakfast, the weird sound the toaster made, and the exact sequence of events that led to them choosing a blue shirt over a green one. They aren't doing it to annoy you. For them, communication is a primary drive. McCroskey’s research suggested that for high-level talkers, the act of speaking reduces their internal anxiety. If they aren't talking, they feel a mounting pressure.
But there’s a flip side. Sometimes, why do people talk so much comes down to a lack of "executive function." This is common in people with ADHD. The brain's "brakes" aren't working quite right. You think of something, and before your filter can say "Hey, maybe don't say that out loud," the words are already in the air. It’s impulsive. It’s messy. And usually, the person feels terrible about it about ten minutes after the conversation ends when the "talker's remorse" finally kicks in.

It's Often About Anxiety, Not Ego
You might think the person blathering on about their vacation is a narcissist. Maybe. But often, it's the exact opposite. Social anxiety is a massive driver of over-talking.
Silence is terrifying for a lot of people.
When a conversation lulls, an anxious person feels the weight of that silence like a physical burden. They think, Oh no, it’s getting awkward. I have to fix this. I have to keep the energy up. So they start rambling. They over-explain. They repeat themselves. They’re basically throwing verbal spaghetti at the wall to see if anything sticks and makes the "awkwardness" go away.
Then you have "cluttering." It’s a speech and fluency disorder that’s different from stuttering. People who clutter often speak in rapid bursts and lose their rhythm. Their thoughts are moving at 100 mph, and their mouth is trying to keep up. It’s not about being self-centered; it’s about a brain that’s processing information faster than it can be articulated.

The "Monitor" Problem: Why They Can't See You're Bored
Most of us have a "social monitor." It’s that little voice that says, Check out their body language. They’re looking at their watch. They’ve stepped back three inches. Wrap it up. Some people just don't have that monitor turned on.
This is often linked to "low self-monitoring" traits. Psychologists note that high self-monitors are like chameleons; they adjust their behavior based on the room. Low self-monitors are the same regardless of who they’re with. If they want to talk about 14th-century pottery, they’re going to talk about it, whether they’re at a funeral or a football game. They aren't ignoring your "I'm bored" signals—they literally aren't registering them as data points.
There’s also the "Briefing Effect." In professional settings, people often talk too much because they want to prove their value. They think that by sharing every single detail of their project, they’re showing how hard they work. In reality, they’re just burying the lead.
Breaking the Loop: How to Deal with Over-Talkers
If you're dealing with someone who won't stop, you have to realize that being "polite" by staying silent is actually enabling the behavior. They think you're interested!
- The Interrupt-and-Redirect: Wait for them to take a breath. It happens eventually. Then, jump in with: "I don't want to lose that point you made about [X], but I really need to mention [Y] before I forget."
- The Time Box: Start the conversation with a boundary. "I’ve only got five minutes before my next meeting, but what’s the update on the project?"
- The Body Language Shift: Don't just stand there. Physically turn your body slightly away. Start gathered your things. Most people will subconsciously pick up on the "exit" energy even if they miss the verbal cues.
What if You're the One Talking Too Much?
If you suspect you're the one who sucks the air out of the room, don't panic. It's a fixable habit. Most over-talkers are just trying to connect, they’re just using a "quantity over quality" approach.
First, try the "Two-Sentence Rule." In casual conversation, try to convey your main point in two sentences, then stop. See if the other person asks a follow-up. If they don't? They probably aren't that interested in the topic, and that’s okay.
Second, practice "active listening" which sounds like a corporate buzzword but is actually a superpower. Instead of planning what you’re going to say next while the other person is talking, try to summarize what they just said. "So, what you're saying is the flight was delayed and you missed the wedding?" It forces your brain to stop generating its own "content" and actually process someone else's.
Actionable Steps for Better Balance
Understanding why do people talk so much is the first step toward better relationships. Whether it's you or someone you love, the goal isn't silence—it's connection.
- Identify the Trigger: Is the talking happening because of stress? Alcohol? A specific topic? Notice the patterns.
- The Wait Rule: Wait three seconds after someone finishes speaking before you start. This prevents "overlapping" and ensures they were actually done.
- Ask More, Tell Less: Goal-set to ask three open-ended questions for every one story you tell.
- Watch the Eyes: If the person you're talking to looks away more than three times, wrap up your sentence. Now.
Communication is a two-way street, but sometimes we get stuck in a one-way cul-de-sac. By recognizing the dopamine hits, the anxiety, and the lack of monitoring that causes over-talking, you can steer the conversation back to a place where both people actually get to exist.
