Could you recognize the names of the three main characters from the Harry Potter series if you saw them out of context? Think you could identify a trio of Shakespearean plays, or iconic Chevy models? Take this quiz to see if you can figure out what these objects, items or names have in common!

Your brain is pretty incredible, and while you might not give it a whole lot of attention, it's quietly operating in the background of your life like the world's greatest supercomputer. Not convinced? The National Science Foundation estimates that an average human has between 12,000 and 50,000 thoughts every single day. On top of all those thoughts, we're inundated with sights, sounds, smells, tastes and countless interactions with people as we go about our daily routines.

And somehow, with all those thoughts and all that input, your brain manages to keep everything straight, all while also controlling basic human functions like breathing, circulation, walking and talking. Even more amazing is that your brain manages to store that information and file it instantly so you can pull it up again when you need it.

So how does your brain manage all that? In many cases, those gray synapses get the job done by finding patterns and using them to assign thoughts or information to categories, rather than trying to process each bit of info individually.

Think you can spot these patterns and figure out what groups of items have in common? Take our quiz to find out!
