What is the evolutionary value of blushing? It seems not to be to our advantage to do it, to involuntarily reveal our inner emotions. If we're trying to manipulate or lie, actions in furtherance of individual goals as opposed to the goals of others, blushing would not seem to be helpful. And yet everyone blushes, except the psychopath.
From Frans de Waal
I have often noticed how primate groups in their entirety enter a similar mood. All of a sudden, all of them are playful, hopping around. Or all of them are grumpy. Or all of them are sleepy and settle down. In such cases, the mood contagion serves the function of synchronizing activities.
