Also known as "humans are special", this trope is actually rarer than I expected it to be.

The humans in the Wake graphic novel series are the only species without telepathic powers, which means they're immune to psi abilities and are hard to detect.
In the Grand Central Arena books, while trying to achieve faster than light travel, the crew of a ship end up in the place where all the species of the universe meet. They pretty quickly realize how humans are way more willing to take risks compared to all the other species.
