Some people can see a deer in the woods when no one else can. Some can see a "glitch" in a 19GB file.
Some folks just can. One of my former bosses called it "seeing the holes". One of the tests I had for hiring analysts was a visual test. "What do you see", helped tell me how people think.
I'm good at it, but I don't think I'm anywhere near "The Dude's" status. That's impressive.
