I chose right in the middle.

Let's first get out of the way that knowing more about conspiracy theories does not equal being smarter. Although, there have been a time when I did think that (not unlike many others I suspect), and would most likely have hit the 90% as well.

Having said that. I always had an edge over the people I grew up with but since, I have met many people with more life experience, knowledge, and have at least my IQ.

It was a sobering but a most valuable experience when I started hanging out with different crowds. And also here I suspect that the people who ranked themselves in the upper 80 or 90% should try hanging out with different crowds.
