I like to acknowledge that there is a difference between "knowledge" and "wisdom".

You can be wise while getting the "facts" wrong, and you can be knowledgeable about something without an ounce of "common sense".

There are also reasonable and unreasonable ways to arrive at knowledge/wisdom/truth. Some prefer the path of science/logic, others find the path of spirit/emotion more enjoyable.

If you define "intelligence" as "the same path I took to find truth" then, yea, most people are going to look like idiots from your perspective.
