So you've heard about this personality test everyone's taking - the Myers Briggs Personality Type Test. Maybe your friend won't stop talking about being an ENFP, or your HR department made you take it during training. Honestly, when I first took it years ago, I thought it was just another internet quiz. Boy was I wrong - this thing has actual psychology roots.
What Exactly Is the Myers Briggs Assessment?
The Myers Briggs Personality Type Test (or MBTI for short) is a questionnaire that sorts people into one of 16 personality types based on four key dimensions. It came from this mother-daughter team, Katharine Cook Briggs and Isabel Briggs Myers, back in WWII. Their big idea? Help women find war jobs that fit their personalities. Kinda cool origin story, right?
Now here's where things get real: the test doesn't just slap a label on you. It looks at how you:
- Get energy (Extraversion vs. Introversion)
- Take in information (Sensing vs. Intuition)
- Make decisions (Thinking vs. Feeling)
- Approach the world (Judging vs. Perceiving)
Quick tip: Judging here doesn't mean being judgmental! It's about whether you prefer structure (J) or flexibility (P). Took me ages to understand that.
The Nuts and Bolts: How the MBTI Actually Works
So how does this Myers Briggs Personality Type Test thing function? You answer around 90 forced-choice questions (pick between A or B, no middle ground). Then voilà - you get four letters that supposedly define your personality.
Let me break down what those letters really mean:
E or I
Energy source:
E = Extraversion (social interactions)
I = Introversion (alone time)
S or N
Information processing:
S = Sensing (facts/details)
N = Intuition (patterns/big picture)
T or F
Decision making:
T = Thinking (logic/rules)
F = Feeling (values/impact)
J or P
Lifestyle approach:
J = Judging (organized/planned)
P = Perceiving (flexible/spontaneous)
Combinations create the 16 types like INFJ or ESTP. Ever notice how some people just feel like certain letters? My college roommate was textbook ESFP - always dragging us to parties last minute.

The Good, Bad and Ugly: Pros and Cons
The Upsides
- Self-awareness boost - helps you understand why certain situations drain you
- Relationship insights - explains why your partner needs alone time when you crave connection
- Career navigation - identifies jobs matching your natural strengths
- Team building tool - companies use it to improve communication
The Downsides

- Labeling danger - "I'm an introvert so I can't do presentations" (not true!)
My take? The Myers Briggs Personality Type Test is useful if you don't take it as gospel. When my team did it at work, it sparked great conversations - but we didn't make promotions based on it.
Putting Your Results to Work
So you got your four letters - now what? Here's how to actually use your Myers Briggs Personality Type Test results:
Career Planning
- NT types (INTJ/ENTP) often thrive in tech or engineering
- NF types (ENFP/INFJ) frequently excel in counseling or creative fields
- SJ types (ISTJ/ESFJ) usually prefer structured environments like administration
- SP types (ESTP/ISFP) typically seek hands-on work like emergency services
Relationship Building
Think your partner's being difficult? Might be type differences:
- Judgers schedule date nights; Perceivers prefer spontaneity
- Extravisors process out loud; Introvisors need quiet thinking time
- Feelers discuss emotions; Thinkers focus on solutions
Personal story: Learning my wife's ISTJ vs my ENFP explained our endless closet debates. I wanted it "creative," she needed it organized. We compromised with color-coded chaos!
Top Alternatives to Consider
While the Myers Briggs Personality Type Test is popular, other tools offer different insights:
- Big Five Personality Traits - Measures openness, conscientiousness, extraversion, agreeableness, neuroticism on spectrums. More scientifically validated.
- DISC Assessment - Focuses on behavior: Dominance, Influence, Steadiness, Conscientiousness. Great for workplace communication.
- Enneagram - Identifies core motivations and fears through 9 interconnected personality types. Deeper spiritual angle.
- StrengthsFinder - Pinpoints your top 5 talents out of 34 possibilities. Very action-oriented.
Honestly, I've taken them all. Myers Briggs gives best overall picture, but Big Five feels more scientifically solid.
Your Myers Briggs Questions Answered
Can your Myers Briggs type change over time?
Technically no - but how you express it can evolve. At 20 I tested strong ENFP. At 40? Still ENFP but less E and more F. Life experience changes how traits manifest.
How accurate are free online versions?
Surprisingly decent for basic typing! But professional assessments have better validation checks. I compared free vs paid - got same type but paid gave WAY more insight.
Why do psychologists criticize the MBTI?
Mainly the black-and-white categories. Real personality exists on spectrums. Also test-retest reliability isn't perfect. But many counselors still find it useful regardless.
Can employers require Myers Briggs testing?
Legally yes, but ethically questionable. Type shouldn't determine hiring. My company uses it for team-building only - never for evaluations.
What's the rarest personality type?
INFJ wins (or loses?) the rarity contest at about 1-3% of population. ENTJ women are also uncommon. Meanwhile ISTJs and ISFJs are everywhere!
Before You Take the Test: Practical Tips
- Take it when well-rested - I made the mistake post-red-eye flight and got weird results
- Answer instinctively - don't overthink "what should I pick?"
- Consider work vs home behavior - which feels more authentic?
- Retake if doubtful - 20% get different results on second try
- Don't obsess over "bad" types - there are no inferior results!
Final thought? The Myers Briggs Personality Type Test works best as a mirror, not a cage. It helped me understand why networking events exhaust me and why I thrive brainstorming with others. But it doesn't define what I can become. Your turn now - what will your four letters reveal?
