The MBTI and Academic Medicine: Useful or Overrated?
You Already Know Your Four Letters
Somewhere in your career, probably during a leadership retreat or a faculty development workshop, someone handed you the Myers-Briggs Type Indicator. You answered a bunch of questions. You got four letters. You may have felt seen. You may have felt skeptical. Either way, those letters have a way of sticking around.
I still hear physicians introduce their MBTI type like it explains everything. "I'm an INTJ, so that's why I hate small talk." "I'm an ENFP, which is why I keep saying yes to things." It gets used as shorthand. Sometimes as a shield.
So let me take a step back and ask the question I think more faculty should be asking: Is the MBTI actually telling you anything useful?
What the MBTI Does Well
I'll start with the good news. The MBTI opens doors that otherwise stay shut.
In academic medicine, we don't talk about working styles enough. We assume that smart people should be able to figure each other out. But a room full of brilliant physicians can still be a communication disaster if nobody understands why half the group needs to think out loud while the other half needs to process in silence before speaking.
The MBTI gives people a low-stakes vocabulary for those differences. That's genuinely valuable. When an introverted researcher tells her extraverted department chair, "I need time to reflect before I respond to big decisions," and they both understand that as a preference rather than a problem, real progress happens.
I've also seen it work well in team settings. When a division uses the MBTI as a starting point for a conversation about how they collaborate, it can surface patterns that everyone felt but nobody named. That naming matters. As organizational psychologist Adam Grant has pointed out in his writing, shared language around personality differences reduces the tendency to treat them as character flaws.
Where It Breaks Down
Here's where I have to be direct. The psychometric evidence behind the MBTI has real limitations.
- Test-retest reliability is inconsistent. Research published in the Journal of Career Planning and Employment and elsewhere has found that a substantial number of people receive a different type when they retake the assessment within weeks. If the tool measures something stable about you, the results should be stable too.
- The binary categories don't reflect reality. You're either a Thinker or a Feeler. But personality science has moved decisively toward dimensional models, like the Big Five, that place people on a spectrum. Most physicians I work with are not cleanly one thing or the other. They're analytical in the ICU and deeply empathetic in a mentoring conversation. The MBTI forces a split that doesn't capture that range.
- It can become a label instead of a lens. This is the risk I see most often. A physician takes the assessment, gets a type, and starts using it to explain away areas where they could grow. "I'm just not a Feeling type" becomes a reason to avoid developing emotional intelligence. That's not self-awareness. That's stagnation.
How to Use It Without Being Used by It
If you've taken the MBTI, or if your department is about to roll it out, here's what I'd recommend.
Hold the results loosely. Treat your type as a conversation starter, not a conclusion. Notice where the description resonates and where it doesn't. The gaps are often more interesting than the fits.
Pair it with a stronger tool. The MBTI can spark reflection, but instruments with more robust psychometric backing, like CliftonStrengths or the DISC assessment, tend to give you more actionable insight. Think of the MBTI as the appetizer, not the main course.
Watch for the excuse trap. If you hear yourself using your type to justify avoiding something hard, pause. Growth often happens in the space between your default preference and the demands of your role. A physician leader who "prefers Introversion" still needs to show up visibly for their team.
Focus on the team conversation, not the individual label. The MBTI's best use case is collective. Sit down with your team and ask: How do we each prefer to receive information? Make decisions? Handle conflict? That conversation matters more than any four-letter code.
The Bottom Line
The MBTI is not junk science, and it's not a definitive personality map. It sits somewhere in between: a useful but imperfect framework that can help academic physicians talk about differences they'd otherwise ignore.
The real question isn't whether the MBTI is valid. It's whether you're using any tool at all to understand how you work, communicate, and lead. If the MBTI is what gets you started, great. Just don't let it be where you stop.
