How do you draw a circle? We analyzed 100,000 circles to show how culture shapes our instincts

Let's do a quick exercise. Did you start at the top or bottom? New data show that the way you draw a circle holds clues about where you come from. In November, Google released an online game called Quick, Draw!, in which users have 20 seconds to draw prompts like "camel" and "washing machine." It's fun, but the game's real aim is to use those sketches to teach algorithms how humans draw.
