Should You Take the Myers-Briggs? A Physician's Guide
The Most Popular Assessment You Should Be Skeptical About
If you've been in any kind of leadership development, you've probably taken the Myers-Briggs Type Indicator. Maybe more than once. You got four letters. Someone told you what they meant. You may have nodded along, or you may have thought the whole thing felt like a horoscope with better marketing.
Both reactions are reasonable. The MBTI is the most widely used personality assessment in the world, and it's also one of the most criticized. If you're a physician trying to decide whether it's worth your time, you deserve a straight answer.
Here's mine: it depends on how you use it.
What the MBTI Actually Does
The assessment is based on Carl Jung's theory of psychological types, adapted by Katharine Briggs and Isabel Briggs Myers in the mid-20th century. It sorts your preferences along four dimensions: where you get energy (Extraversion vs. Introversion), how you take in information (Sensing vs. Intuition), how you make decisions (Thinking vs. Feeling), and how you structure your world (Judging vs. Perceiving).
You end up with a four-letter type. INTJ. ESFP. Sixteen possibilities total. Each type comes with a profile that describes how you tend to think, communicate, and work.
The framework is intuitive. Most people read their type description and recognize themselves in it. That recognition is where the value starts. And, if you're not careful, where it stops.
Where It's Useful
I've seen the MBTI do real good in one specific context: opening conversations about difference.
Academic medicine is full of smart people who assume everyone processes information the way they do. The surgeon who leads with rapid-fire decisions can't understand why her research colleague needs three days to respond to an email. The department chair who thinks out loud in meetings doesn't realize his introverted faculty are doing their best work in silence, long after the meeting ends.
The MBTI gives people a simple way to talk about these differences without making them personal. It's not that your colleague is slow. They might just prefer to process internally before committing to a position. It's not that your chair is dismissive. He might need to externalize his thinking to figure out what he believes.
That kind of reframing matters. It can turn frustration into curiosity. And curiosity is a much better starting point for working together.
Where It Falls Short
Here's where I have to be honest. The psychometric evidence behind the MBTI is mixed. Test-retest reliability is a known concern. Studies have shown that a significant percentage of people get a different type when they retake the assessment weeks later. The scientific literature on personality has largely moved toward dimensional models like the Big Five, which measure traits on a spectrum rather than sorting people into binary categories.
The either-or structure is the biggest problem. You're either a Thinker or a Feeler. But most people are somewhere in the middle, and where they fall can shift depending on context. A physician who is highly analytical in the ICU might lead with empathy when mentoring a struggling resident. The MBTI doesn't capture that flexibility well.
There's also the labeling risk. I've watched people use their type as an excuse. "I'm an INTJ, so I'm just not good at small talk." That's not self-awareness. That's self-limitation. Any assessment that gives you a reason to stop growing has been misused.
How to Use It Thoughtfully
If you decide to take the MBTI, hold the results loosely. Treat your type as a hypothesis, not a diagnosis. Notice where the description fits and where it doesn't. Be especially interested in the places where it doesn't, because that's where context, growth, and choice have already overridden your default wiring.
Use it as a conversation starter with your team, not as a sorting hat. The value isn't in knowing that you're an ENFP and your colleague is an ISTJ. The value is in sitting across from each other and saying, "Here's how I tend to work. Here's what I need. What about you?"
And pair it with something more robust. The MBTI can open the door to self-reflection. But tools with stronger psychometric foundations, like CliftonStrengths or DISC, tend to give you more to work with when it comes to making real changes in how you lead and communicate.
The Bottom Line
The MBTI isn't useless, and it isn't gospel. It's a starting point. For physicians in academic medicine, where collaboration across wildly different working styles is the daily reality, even a flawed framework can be valuable if it gets you talking honestly about how you show up.
Just don't let four letters define you. You're more complicated than that. And so is everyone you work with.
