Social sensitivity, as measured by these experiments, is really about understanding what people around you may be feeling based on small cues. The classic test used to measure social sensitivity is the “Reading the Mind In the Eyes Test” which you can take online. Again, it makes sense that this skill was evident in furthering collective intelligence. Being able to quickly look around a table and determine that one person is very confident in their knowledge, another is impatient with the task, and another wants to share information but isn’t feeling able is going to be a big advantage in getting the group working together at maximum potential.
