The next section is concerned with the effects of design on human behavior. Look at the two crosswalks on the screen. One is ordinary but the other one is unusual because it has a diagonal pattern. Why do you think it’s designed this way?
　You normally walk straight across a road, but when you see this new crosswalk, you are subconsciously tempted to walk toward the right. As a result, people walking across from either side of the road don’t bump into each other. This is a good example of how design can change people’s behavior.
　Making a diagonal line on a crosswalk is much easier than posting a “KEEP RIGHT” sign in multiple languages. It is also more effective because design sometimes speaks louder than words. This type of design is called “persuasive design.”
