This research is simply raw data, which may or may not be of use in the long run. But studies like this are often a starting point to finding deeper truths. Maybe the results of this study will lead to the understanding of why some people have a more fully developed social network, and therefore simply communicate more within that network. Maybe it will lead to a discovery that the data-gathering techniques were flawed, and there is no real difference. The point is, we cannot stop studying the world around us, particularly ourselves, out of fear of being a labeled racist or sexist.
