Every major personality test, compared
Six instruments, side by side: what each one measures, how it measures it, how well the evidence holds up, and what you get at the end.
We built Haliscope because none of these did the job we wanted done. That’s a biased starting position, so these pages are written to be checkable rather than persuasive — where an instrument is good, we say so; where the evidence is contested, we say that too.
The master table

Comparison 01
Haliscope vs. the MBTI
The most widely administered assessment in the world sorts you into one of sixteen boxes. Where it came from, why it caught on, and what the reliability literature actually says.
Comparison 02
Haliscope vs. the Big Five
The honest one. The Big Five is the best-validated model of personality structure available, so the argument isn’t that it’s wrong — it’s what HEXACO adds, and what occupational data does with it.
Comparison 03
Haliscope vs. Enneagram
Nine types drawn from a spiritual tradition, widely used for self-reflection and rarely tested empirically. What it’s good for, and why it can’t do career matching.
Comparison 04
Haliscope vs. 16Personalities
A Big Five instrument wearing a four-letter costume. The underlying measurement is sound; the decision to report it as a type is where the information goes missing.
Comparison 05
Haliscope vs. CliftonStrengths
A well-built development tool that ranks your talents against each other. Why that design is right for a coaching conversation and wrong for a career decision.
How to choose between them
Three questions settle most of it. None of them are about which test is most popular.
Does it report traits or types?
Measured across a population, traits are continuously distributed — most people cluster near the middle rather than at either pole. An instrument that reports a type turns that spectrum into a switch, which is why people near the midpoint often get a different result on a retake. Traits keep the information; types discard it.
Is the career mapping real, or implied?
Most personality instruments were never built to recommend jobs. When they list careers, the list is usually editorial rather than derived. Ask whether the recommendations trace back to occupational data — job tasks, work styles, required interests — or to somebody’s sense of what an ENFP might enjoy.
Can you check the work?
A serious instrument publishes its model, its scoring approach and its limitations. If you can’t find out how a result was produced, you have no way to tell measurement from a well-written horoscope. Ours is on the methodology page, limitations included.
