You’re standing in line at the grocery store. The person ahead of you is fumbling with their digital coupons, and you feel that familiar prickle of heat rising up your neck. You check your watch. You tap your foot. You've already mentally reorganized your "to-do" list for the next three hours because this three-minute delay has thrown a wrench in your perfectly timed afternoon.
If that sounds like your Tuesday, you’ve probably asked yourself: am i type a or type b?
But here’s the thing. Most people think these labels are just fun personality quirks, like being a Leo or an introvert. They aren’t. The whole concept actually started in a cardiologist's waiting room in the 1950s because the chairs were wearing out in a very specific way. Meyer Friedman and Ray Rosenman, two doctors, noticed their heart patients weren't sitting back and relaxing. They were literally sitting on the edge of their seats, wearing out the front edges of the upholstery.

That frantic energy became the blueprint for Type A.
It wasn't just "being a go-getter." It was a medical observation linked to coronary heart disease. Today, we’ve turned it into a badge of honor or a convenient excuse for being chill, but the reality is way messier and a lot more interesting than a binary choice.
The Stress Junkie vs. The Slow Burner
Type A individuals are often described as the "workaholics" of the world. They have this internal metronome that’s always ticking just a little too fast. If you’re wondering, am i type a or type b, look at your relationship with time. Type A people suffer from "hurry sickness." They hate waiting. They multitask even when they don’t need to—like brushing their teeth while reading emails or trying to cook dinner while on a conference call.
There’s a specific cocktail of traits here: competitiveness, a high need for achievement, and a weirdly persistent sense of urgency.
On the flip side, Type B is the "mellow" counterpart. If a Type A person sees a deadline as a brick wall screaming at them, a Type B person sees it as a helpful suggestion. They’re not lazy. That’s a common misconception that drives Type Bs crazy. They just don't derive their self-worth exclusively from how many boxes they checked off before noon. They tend to be more reflective, creative, and—honestly—a lot less likely to have a meltdown when the Wi-Fi goes down for ten minutes.
It’s about the nervous system. Type A folks live in a state of sympathetic nervous system dominance—fight or flight. Type B folks spend more time in the parasympathetic lane—rest and digest.
Why the Science Behind "Am I Type A or Type B" Changed
We used to think being Type A was a direct ticket to a heart attack. The original studies by Friedman and Rosenman suggested that Type A's were twice as likely to develop heart disease. But later research, including a massive meta-analysis by the American Heart Association, started to poke holes in that.
It turns out, being "ambitious" or "fast-paced" isn't what kills you.
The "toxic" element of the Type A profile is actually hostility.
Redford Williams, a researcher at Duke University, spent years breaking this down. He found that if you’re Type A but you’re generally a happy, driven person, your heart is probably fine. But if your Type A traits come with a side of cynicism, anger, and a tendency to snap at the barista, that is what triggers the physiological stress response that damages arteries.
So, when you ask, am i type a or type b, the better question might be: "Am I Type A with a short fuse?"
The Ambivert of Personalities: Enter Type C and Type D
The world loves a binary, but humans don’t work that way. While everyone focuses on the A/B split, psychologists eventually realized they were missing huge chunks of the population.
Type C: The Detail-Oriented Suppressor
Type C people are the ones you want auditing your taxes. They are incredibly detail-oriented, patient, and logical. However, they have a hard time expressing emotion. They tend to "bottle things up" to keep the peace. Some early (and controversial) studies even tried to link Type C traits to cancer progression because of the way chronic emotional suppression affects the immune system, though that link is much weaker than the Type A-heart disease connection.
Type D: The Distressed Soul
Type D is the "Distressed" personality. This was coined by Johan Denollet at Tilburg University. These folks feel a lot of negative emotions but, unlike the explosive Type A, they inhibit those feelings socially. They’re prone to anxiety and depression. If Type A is an erupting volcano, Type D is a slow-cooking pressure filled with steam that has no vent.
Is Personality Permanent? (The Neuroplasticity Factor)
You aren't stuck. If you took a "Which personality are you?" quiz in a magazine in 1995 and it told you that you were Type A, that doesn't mean you're doomed to a life of high blood pressure and broken watches.
Our personalities are surprisingly plastic.
A Type B person can develop Type A habits if they take a high-pressure job in Silicon Valley. A Type A person can learn to cultivate "Type B" traits through mindfulness, cognitive behavioral therapy (CBT), or simply by getting a dog that refuses to walk faster than a snail’s pace.
Think of it like a spectrum. Most of us are somewhere in the middle, sliding back and forth depending on how much sleep we’ve had or how much caffeine is in our system. You might be Type A at work—organized, fierce, and punctual—but Type B on the weekends, where you can't be bothered to even find your shoes. This is often called being "Type A-minus" or a "situational Type A."
The Hidden Perks of the Type B Life
We live in a culture that worships the Type A "hustle." We’re told that if we aren't "killing it" 24/7, we’re failing. But Type B individuals have a massive secret weapon: longevity in creativity. Because Type Bs aren't constantly redlining their engines, they often avoid the catastrophic burnout that hits Type As in their 30s or 40s. They have the "low and slow" approach to life. They’re often better at complex problem solving because they aren't rushed. They allow ideas to marinate. While the Type A person has finished three mediocre projects, the Type B person is still working on one—but it’s a masterpiece.
Also, Type Bs are generally more pleasant to be around in a crisis. When the ship is sinking, the Type A person is yelling orders and counting the lifeboats (which is helpful!), but the Type B person is the one keeping everyone calm so they don't trample each other.
How to Handle Being a Type A in a Type B World (And Vice Versa)
If you've realized you're firmly in the Type A camp, the goal isn't to stop being productive. It's to stop being reactive.
- The 90-Second Rule: When someone cuts you off in traffic, remind yourself that the physiological surge of adrenaline lasts about 90 seconds. If you’re still mad after two minutes, you’re choosing to keep that stress alive.
- Practice Waiting: Seriously. Get in the longest line at the grocery store on purpose. Don't look at your phone. Just stand there. It’s like weightlifting for your patience muscles.
- Audit Your Hostility: Are you mad at the situation, or are you mad at the person? Separating the two can save your heart.
If you’re Type B and you’re struggling to keep up with a Type A world:
- Use External Deadlines: Since your internal clock is a bit loose, use external "hard" stops. Don't say "I'll finish this today." Say "I'll finish this by 2:00 PM so I can go get a coffee."
- Communicate Your Process: Tell your Type A boss or partner, "I'm not ignoring this, I'm just letting the ideas settle so the final result is better." It stops them from hovering.
- Value Your Chill: Don't let society convince you that your lack of frantic energy is a flaw. It’s your greatest asset for mental health.
Finding the Middle Ground
Honestly, the whole am i type a or type b debate is mostly a tool for self-awareness. It’s not a box; it’s a mirror.
If you look in that mirror and see a person who is constantly vibrating with tension, maybe it’s time to lean into some Type B habits. If you see someone who is so laid back they’re falling over and missing opportunities, maybe a little Type A structure wouldn’t hurt.
The most successful people—and the healthiest ones—are usually "Versatile." They can turn on the Type A drive when a project is due, but they can switch to Type B mode the moment they walk through their front door. They know when to push and when to let go.
Practical Next Steps for Your Personality Type:
- If you identify as Type A: Identify one "non-productive" hobby that you do purely for joy, not for achievement. No tracking stats, no leaderboards, no "winning." Just doing.
- If you identify as Type B: Pick one area of your life—just one—where you commit to "Type A" levels of organization. Maybe it’s your morning routine or your filing system. See how that structure actually frees up more time for your relaxation.
- For everyone: Track your "hostility" levels for three days. Every time you feel a flash of genuine anger at a minor inconvenience, jot down what triggered it. You might find that your "personality type" is actually just a collection of habits you can change.
At the end of the day, you aren't a letter of the alphabet. You're a human being with a nervous system that needs both the gas pedal and the brakes to function correctly. Use both.
