A place for hard tests and honest intelligence talk

IQMean exists for people who love intelligence but dislike the way intelligence gets marketed. The internet rewards extremes: the highest number, the rarest percentile, the most dramatic claim. Real reasoning is quieter. It is a discipline of checking what follows, what does not follow, and what only “sounds” true because the story is persuasive. The Anathema series was built for that discipline, and the IQ Profiles directory exists to keep the public conversation about intelligence anchored to evidence instead of hype.

Many visitors arrive through search queries that look almost identical: “Nikola Tesla IQ,” “Leonardo da Vinci IQ,” “William James Sidis IQ,” “Marilyn vos Savant IQ 228,” “Christopher Langan IQ,” “Rick Rosner IQ.” Those searches reveal the same impulse: to explain greatness with one number. But IQ is not a trophy and it is not a biography. It is a standardized statistic about performance on a particular kind of task under particular conditions. Sometimes a score is well documented. Sometimes it is reported secondhand. Sometimes it is a guess that has been copied so many times that it feels official. IQMean separates these cases because the difference matters.

The Anathema series: five tests, one spine

The five Anathema exams are separate tests that form one arc. Each part isolates a different cognitive pressure, and the series is intentionally designed so that discipline matters more than speed. Every item is multiple choice with ten options (A–J), which reduces guess advantage and increases the cost of sloppy reasoning. Your results show only raw score and final raw score, and every test allows one attempt plus one retake. Your final raw score is the higher of the two.

Why raw scores come first

IQMean uses an auto-norming approach: as more people take a test, the distribution of raw scores becomes clearer. Until a test has at least 100 recorded scores, IQMean shows raw results only. Once enough data exists, the mapping between raw score and IQ becomes meaningful, and IQ and percentile can be displayed responsibly. This protects you from a common failure in online testing: inflated early scores that collapse later when the test finally gets a real sample.

Famous IQ stories: what to read, and how to read it

The IQ Profiles directory is not a hall of worship for numbers. It is a research library for the public conversation. Some people became famous through a documented test story. Some became famous through achievement, then had an IQ assigned to them by later writers. And some became famous because the myth itself was irresistible.

Start with William James Sidis if you want to see how legend forms. Sidis was a genuine prodigy, but the extreme IQ ranges attached to him are not supported by a preserved standardized report. His profile shows the difference between “this person was extraordinary” and “this number is a verified measurement.”

Read Nikola Tesla and Leonardo da Vinci if you want to understand why people try to retrofit IQ onto historical greatness. Tesla’s mind is often described through visualization and engineering synthesis. Da Vinci’s mind is visible in notebooks, observation, and integrative thinking across art and science. In both cases, the genius is clear while the exact IQ number is not.

Read Marilyn vos Savant if you want a modern example where the IQ story has a clearer public chain. Guinness listed her in the “Highest IQ” category and later retired the category itself, which is an important detail: the public wants a single record-holder, while psychometrics does not support a simple universal scoreboard across different tests and norms.

Read Christopher Langan and Rick Rosner if you want to see how IQ and media culture interact. Both are tied to high-score narratives, but their public reputation is shaped by interviews, social framing, and how stories travel. IQMean profiles emphasize sources, context, and what is actually documented.

A short psychometrics map

Most modern IQ scales use a mean of 100 and a standard deviation around 15. That framing makes IQ a percentile story: an IQ value corresponds to a position in a distribution. The higher the score, the rarer the percentile. But rarity language must be handled carefully. Different tests use different item pools, different ceilings, and different norming samples. This is one reason Guinness retired “highest IQ” as a record category: it is difficult to compare scores across instruments, years, and populations without collapsing nuance into a misleading headline.

IQMean’s scoring approach is designed to stay honest to the statistics. Raw scores come first. Norms come only after enough people have taken the test. When norms mature, IQMean can map raw score to a stable percentile in a way that is consistent across the site. Until then, the site refuses to pretend that a tiny early sample is a true norm. This protects you from false inflation and it protects the directory from turning into a scoreboard built on unstable data.

Why Anathema uses ten options (A–J)

Many online tests use five options per question because it is convenient. Anathema uses ten options because it changes the incentives. When you have more possible answers, guessing becomes less effective and careless elimination becomes more dangerous. Ten options pushes you toward actual reasoning: you must understand the constraint well enough to choose the right answer, not merely avoid the worst one. It also makes the tests harder to “game” by pattern-guessing, which is essential for a site that wants honest results.

How to use this hub

If you want the cleanest path, begin with Part 1, then Part 2. If you prefer visual reasoning, begin with Part 3, then Part 4. If you want the full synthesis, take Part 5 after you have completed at least one earlier part. Use the IQ Profiles directory to explore how intelligence is discussed in public history and to compare the difference between a documented claim and a viral one.

The point is not to join an argument about who “wins.” The point is to develop a sharper relationship with evidence and with your own thinking. That is what the Anathema series measures, and that is what the IQ Profiles directory is for.
