93% rated accurate by friends and colleagues

Don't take our word for it. Ask their friends.

Any personality test can claim to be accurate, but Crystal asks real people to rate each other's results. Across 22,902 ratings in our most recent study, 93.3% rated the results accurate.

93.3%

of ratings called the results accurate (4 or 5 out of 5). That's 22,902 ratings from 3,287 reviewers, of 1,698 people's results.

Average rating: 4.6/ 5; average accuracy rating
Perfect score: 68.4%; gave a perfect 5-star rating

How reviewers rated what they read

Each reviewer knows the person and reads that person's results, then rates each assessment from 1 to 5.

Every framework, rated by reviewers

Framework	Average	4 or 5Rated 4 or 5	Ratings
Core Values	4.72	96.4%	3,755
Strengths	4.68	94.6%	3,749
Enneagram	4.58	92.1%	3,817
Big Five	4.54	92.5%	3,860
16 Types	4.54	92.3%	3,796
DISC	4.54	91.9%	3,925

And from users themselves

Nearly 9 in 10 users who rated their results call them accurate.

After each assessment, users can rate how accurate their own result felt. Of the 8,313 who did, 87.5% rated it 4 or 5, for an average of 4.4 out of 5 across 24,909 ratings. Rated as a whole, the full profile averages 4.42.

Reviewers rate a result higher than the person does on all six frameworks, 4.60 against 4.41 overall. The gap is widest on the Enneagram and narrowest on Strengths, and the likeliest reason is the simplest one: a friend asked to judge a description of someone they know has every reason to be generous.

Steady as Crystal grows

Q2 2026: 4.42; 9,178 ratings
Q3 2026: 4.41; 15,780 ratings

Rating volume nearly doubled from one quarter to the next, and the score held.

About these numbers

Measured from Crystal's own data on September 24, 2026. Reviewers are colleagues and friends the user invites, so these ratings show how accurate results look to the people who know someone. They are not a scientific validity study, and reviews here mean a person reviewing a profile, not academic peer review. Rating is voluntary, so figures describe the people who chose to rate. The review program has run since April 2026. Staff, demo and test accounts are excluded, as are reviews of results that were later retaken.

100x deeper than a single personality test
A test gives you a type. Crystal gives you the whole picture.
A personality test reads you one way and gives you one result. Crystal reads you through six assessments, shows you where your personality came from, and learns more about you every day.

Your sharpest hour comes right after your afternoon walk.
Tuesday

Busy days don't stress you out much. Days with no clear end do.
Wednesday

Your ideas stall when nobody owns the follow-up.
Thursday
Decisions & Communication
People trust your decisions more than your explanations.
Friday
Growth & Vision
The goal you talk about most gets the fewest of your hours.
Saturday
Relationships
People who argue back recharge you more than easy agreement.
Sunday
Personality
You usually start more than you finish. This week you didn't, and you were happier for it.
How much deeper, measured
Each assessment reads a different side of you, so each one narrows the group of people like you. Your 16 Types result alone is shared by 1 in 13 people. Add DISC and the Enneagram and it's 1 in 1,250, about 100 times more specific. Of the people who take all six, 99.3% are already one of a kind. Measured on 13,028 real Crystal users.
More depth does not mean more guesswork: 93.3% of the friends and colleagues who rated someone's Crystal results called them accurate. See the benchmarks
About these numbers
Measured from Crystal's own data on October 2, 2026, using each person's latest result on each assessment. Staff, demo, and test accounts are excluded, as are types people typed in rather than tested. “Share your result” is the average, across people, of how many others hold the same result. The 16 types are not evenly spread: the most common is held by 11.9% of people and the rarest by 1.4%. The 100x compares your type alone with your personality blend, on the same 13,028 people (7.9% against 0.08%, 99x, rounded; the blend figure, 1 in 1,248, is shown as 1 in 1,250). The all-six figure is a floor: with 10,327 people, no profile can be measured as rarer than 1 in 10,327. “A single personality test” means one that gives you one of 16 types. Myers-Briggs and MBTI are trademarks of the Myers & Briggs Foundation; Crystal is not affiliated with them. Crystal's own four-letter assessment is the 16 Types.

Coaching cost is a typical six-month engagement of $9,000 to $25,000, spread monthly, from published 2026 executive coaching rate surveys.

Easier than keeping a daily journal
Journaling works. Keeping it up is the hard part.
Lots of people start a journal. Far fewer keep one going, because every day it's on you to find the time, face a blank page, and remember to come back. Crystal makes the habit easy: a few minutes, morning and evening, with the questions ready.

A note from the founder

Personality tests are useful tools, because they often put words to things that we already know to be true about ourselves and others. But a personality test can only tell you so much: it captures one dimension of your personality, at one specific point in time.

Crystal’s goal is to provide the deepest, most accurate picture of your personality with a combination of traditional assessments, AI-powered analysis, self-reflection, and peer reviews. With that information, we can help you understand others better, create a clear vision of your future, and provide personalized coaching to help you turn it into reality.
