People around the world paint their walls different colors, buy plants to spruce up their interiors and engage in a variety of other beautifying techniques to personalize their homes, which inspired a team of researchers to study about 50,000 living rooms across the globe.
In a study that used artificial intelligence to analyze design elements, such as artwork and wall colors, in pictures of living rooms posted to Airbnb, a popular home rental website, the researchers found that people tended to follow cultural trends when they decorated their interiors.
