Side Project: IQ and the Human Population

I work on side projects in addition to, you know, work-work and writing. This is one of them. It’s a single-page website that shows some fun stats about IQ as it relates to the overall human population. The fact that there are 7.5ish billion people in the world right now has some unexpected implications. For example, “superior intelligence” is rated as something like and IQ of 110–119. Want to know how many people in the world have an IQ of 115 or above (i.e. termed “superior” or higher)? Over a billion.

Yes. More than a billion people.

Pretty cool.

The site also shows the uniform odds that any given person would have someone at a certain IQ level or higher within their social circles: family, close friends, colleagues acquaintances, etc.

If you’re into personality testing and/or IQ stuff, give it a look!
