Research has shown that when speaking in front of a group, people’s attention tends to gets stuck on the most emotional faces, causing them to overestimate the group’s average emotional state. In this piece, the authors share two additional findings. First, the larger the group, the greater this attention bias. Second, the attention bias is stronger for faces expressing negative emotions than for faces expressing positive ones, meaning that our ability to judge a group’s emotional state isn’t just skewed towards more intense emotions — it is specifically biased toward more negative evaluations. Based on these findings, the authors suggest that when giving a talk or meeting a large group of people, we should attempt to intentionally scan the audience more evenly in order to counteract our natural attention biases and get a more accurate picture of the group’s overall emotional state.
