This post was originally going to be titled "How Skateboarding Helped My Education," but by the end hopefully you'll see why education was swapped for intelligence. Though related, the two are not the same thing.
One way people learn things is by observation, which humans have been using to test claims long before science arrived on the scene. Science and its tools merely extend or accentuate our observational abilities, with the added bonus of providing a somewhat reliable filter for false claims. How does this relate to skateboarding?
