Facebook decided to focus on the sentiments its users expressed most often. Zhuo and the team began by analyzing how a subset of Facebook users from around the world used the platform. They looked at the most frequently used stickers, emoji, and one-word comments and found a few common emotional threads amidst an ocean of diverse sentiments. “When we built the stickers for Facebook the most common thing people sent was love,” Keltner says. People used the hearts-in-the-eyes emoji more than any other. They were also prone to expressing humor, sadness, and shock through visual means. The team took a subset of reactions that cut across the emotional spectrum and removed redundancies like sympathy and sadness, and joy and love. Then they tested them with users.
