RarityQuiz.com was built by IaaS Academy Limited — a UK-based company passionate about using data and psychology to help people understand themselves better.
We started with a simple question: in a world of 8 billion people, how unique are you really? Not in a motivational-poster way — but statistically, psychologically, genuinely.
The answer turns out to be: far more unique than most people realise. When you combine even a handful of traits — your name, your eye colour, how you process emotions, what keeps you up at 3am — the number of people who share your exact profile shrinks dramatically.
We built the Human Rarity Score to make that tangible. To give people a number they can point to and say: this is how rare I am.
We do not store, collect, or share any of your quiz answers. The quiz runs entirely in your browser. When you close the tab, your data is gone. That is not a policy compromise — it is a design principle.
The rarity score is rooted in real population statistics and psychological research, but it is designed to be thought-provoking and entertaining — not a clinical diagnostic tool. We are clear about that distinction, and we think it matters.
We believe curiosity about yourself and others is one of the most valuable things you can cultivate. RarityQuiz is one small nudge in that direction.
RarityQuiz.com is a product of IaaS Academy Limited, a company registered in England and Wales. We build digital tools and educational products that sit at the intersection of data, psychology, and human understanding.
