Editorial Team
Five people write and check what you read here: the 16 personality type profiles, the test explainers, the famous-people typings and every number in them. This page says who covers what, who signs a page off before it is published, and how to tell us when we have got something wrong.
Personality types are easy to write about badly.
Too flattering, too certain, too much like a horoscope. Every page on this site has a named writer and a named reviewer, so if a claim is wrong you know who to hold to it.
This team writes and checks the type guides on Insight Metrics: the profiles of all 16 personality types, the pages around our personality test and the FAQ. For who we are as a company, see About Insight Metrics; to reach the team, use the contact page.
Who writes what.
Every section has someone who signs it. The byline on each page links here, to whoever wrote and reviewed it.
Aarav Vardhan
Editor-in-ChiefAarav decides what Insight Metrics publishes and what it does not. He owns the language the site uses about results: that a four-letter type describes preferences rather than abilities, that each score shows how clear a preference is rather than how much of a trait you have, and that one sitting is an indication, not a verdict.
He is the standing reviewer on anything that interprets a result for a reader: the 16 personality type profiles, the personality test page and the FAQ. He also holds the line the site does not cross, that this is a self-discovery assessment and not a clinical one, and he is the named contact for corrections.

Alden Cross
Research WriterAlden writes the long-form explainers: the 16 personality type profiles, the guide to cognitive functions, and the pieces that set type theory next to modern trait research such as the Big Five. These are the pages that have to take a slippery idea and leave the reader holding it correctly.
His working rule is that the caveat belongs in the same paragraph as the claim. He works from the primary sources, Jung’s Psychological Types, Myers’ Gifts Differing, the MBTI Manual and peer-reviewed research, rather than from other personality websites, and where the evidence is contested he says so instead of picking the tidier answer.

Leon Falkner
Data & Research AnalystLeon owns the numbers: how common each type is, the splits by gender, the score scales in our reports and every table that compares types. A frequency figure is only meaningful with its sample, its country and its year attached, and keeping those attached is his job.
He also checks the figures in everyone else’s drafts, which is where most errors on a site like this would otherwise get through: a percentage taken from a different sample than the one cited, two sources blended into one table, or a rarity figure that has quietly lost a decimal place.

Elora Mercer
Famous Personalities WriterElora researches the famous-people and fictional-character typings. Her part is the person rather than the label: what is actually documented about someone, whether they have ever shared a type result themselves, and which typings have simply been repeated between websites until they started to look like facts. Where the record is thin, the profile says so.
The discipline that matters is restraint. “Often typed as ENFP” and “is an ENFP” are different claims, and she keeps them apart.

Arjun Vardhan
News & Research WriterArjun writes the study write-ups: pieces that take a newly published paper on personality and set out what it actually found, who it studied and how far the finding travels beyond the sample it came from.
He also covers how personality assessments are used in practice, by employers, coaches and schools, where that use is supported by evidence and where it has run ahead of it.

Six rules we hold ourselves to.
These six rules decide what gets published on Insight Metrics and what gets sent back.
Every number has a source
A figure, such as how common a type is, traces to a named study, manual or dataset, or it is labelled an estimate in the sentence that carries it. If a widely repeated number has no verifiable origin, we say so instead of repeating it.
Nothing here is a diagnosis
Insight Metrics runs a self-report personality assessment. A type describes preferences, not ability, intelligence or mental health. It diagnoses nothing, and it should never be the only basis for a hiring decision. Any page that starts to read like a diagnosis gets rewritten.
A person reviews it, and we name them
Nothing that interprets a result, reports a statistic or describes research goes live on one person’s draft. It is reviewed first, and the reviewer’s name is printed on the page, so if a claim is wrong you know who to hold to it.
Famous people are typed carefully
Very few public figures have shared an official type result. When we name the likely type of a celebrity or a character, we say it is an unofficial typing and what it is based on, instead of presenting it as fact.
The science stays in the same paragraph
Type theory comes from Jung and from Myers and Briggs; most academic research today studies traits, such as the Big Five. Where the evidence is limited or contested, the caveat sits next to the claim, not in a footnote nobody reads.
Corrections are dated, not silent
When we get something wrong, we fix it and say what changed, with the date, at the foot of the page. Quietly editing a page and moving on is how a site loses the right to be believed.
What happens before a page goes live.
The same five steps for a type profile, a test explainer and a famous-people typing.
Commissioned
A topic goes to the person who covers it, with the questions the page has to answer stated up front.
Written from sources
Drafted from the theory, manual or study itself, not from other sites. Anything unverifiable is labelled.
Figures checked
Every percentage, frequency and scale is checked against its source before the draft moves on.
Editorial review
Read for accuracy and overreach, especially sentences that sound more certain than the evidence.
Published and dated
Goes live with the writer’s byline, the reviewer’s name and the date. Corrections are added at the foot, dated.
