We know it's a myth that "humans only use 10% of their brains," but there might be a function of your mind that you're neglecting to use: its sandboxes. Eric Weinstein borrows this term from computer science to explain the potential of experimental thinking. A sandbox in computing is a secured place where untrusted software can run without controlling the computer or accessing its vital resources. Security specialists, for example, use sandboxes to analyze how malware behaves. Once they see and understand how it works, they can then devise a strategy to defeat it, and strengthen their own system to prevent it from getting in again.
