When it comes to college-aged adults who are glued to their smartphones, experts argue over whether texting while walking increases the risk of an accident. Some studies have shown that texting pedestrians are more likely to walk into oncoming traffic, while other studies suggest that young adults have mastered the art of multitasking and are able to text accurately while navigating obstacles. However, few studies have measured how texters respond to unpredictable hazard conditions. By simulating an environment with random slipping threats, researchers report that texting increases the risk of falling in response to walkway hazards.
