About this site
Our Editorial Policy
On this page
Every page on IQ Score Level is researched from primary sources and checked before it goes live. When it is wrong, it is corrected in public. This page explains the rules we follow and how you can hold us to them.
How are facts chosen and checked?
Facts come from primary sources, and each one is checked before it is used. Primary sources are the original documents. Examples are test publishers’ materials, peer-reviewed papers, official Mensa pages and texts of laws.
Each fact is logged in our facts register with its source, before it goes on a page. If we cannot find a primary source, the fact stays off the page. If the page needs it anyway, the page says plainly that it is not verified.
Some sources disagree, and some popular numbers have no solid origin. We do not print those as fact. We explain where the number came from instead. Our page on Einstein’s IQ is an example.
How are numbers computed?
Numbers about the bell curve are computed by code, never typed by hand. Percentiles, “1 in X” rarity and conversions between test scales all come from one tested module. The same module runs the test, the IQ calculator and every score page.
Numbers about the test itself come from the live code and data. Settings such as the number of questions come from one configuration file. Counts of test takers come only from our database. They stay hidden until they are large enough to mean something.
How are AI tools used?
We use AI tools to help draft pages and build the site. Every fact in a draft is then checked against its primary source. Every number is computed by code, not taken from the draft. A person, Owen Hartley, is responsible for everything we publish.
AI tools never invent sources, quotes, reviews or statistics on this site. If a draft contains something we cannot verify, it is removed.
What do we avoid?
We avoid anything that would mislead a reader or a search engine. We do not publish pages made mainly to rank. We do not repeat the same text across many pages. Our score pages each carry their own computed numbers and are checked for repeated text.
We never call the site official or claim a link with Mensa or any test publisher. We never show fake reviews, fake counts or fake “updated” dates. We do not compare IQ by race or ethnicity. We do not give medical advice.
Who reviews the pages?
Right now, Owen Hartley checks every page against the sources and the rules on this page. No outside expert has reviewed our pages yet, so no page claims one. If a qualified reviewer checks a page in the future, the page will name them.
How do we handle corrections?
We correct errors as soon as we confirm them. A correction changes the page itself. A short note is added to the list below. Changes to the test and its scoring are listed separately in our methodology.
You can report an error through the contact page. Please name the page and the sentence, and tell us your source if you have one.
Corrections list
No corrections have been needed on published pages so far.
Why do we work this way?
We work this way because an IQ result matters to people. A wrong number can mislead them. Google’s guidance on helpful content asks for reliable pages made for people, not to game rankings. We agree, and this policy is how we try to meet that standard. Read more about this site. Our sources and credits page lists every source, tool and trademark we use. Or take the free test yourself.
