At least to some scientists it is. Scientists believe that catching a yawn is a sign of empathy, since it is more likely to occur between relatives than strangers. Plus, other social primates like chimps and bonobos do it, too. A new study suggests that women (traditionally branded the more empathetic sex) might be more susceptible to copycat yawning than men. Researchers surreptitiously analyzed more than 4000 real-world yawns on planes and trains, in restaurants, and in offices. They noted when someone yawned, and then whether a nearby acquaintance or friend did the same within a 3-minute period. Men and women spontaneously yawned with about the same frequency. But when someone else yawned first, women were more likely than men to follow suit. Women picked up yawns about 55% of the time, whereas men only did so 40% of the time. Women tend to score higher than men on tests of empathy, and traditional female social roles (like child-rearing) place a higher emphasis on those traits. That might make women more attuned to others’ yawns, the researchers suggest.
