New psychological research shows a clear link between humility, as a personality characteristic, and helping, an action one does for the benefit of others.
Researchers discovered that humility is strongly associated with a host of positive values, including reliable friendship, good working habits and generosity. Evolutionary psychologists say there's good reason for that: "Humble people will be more helpful to the group because a trait that involves subsuming one’s own needs to those of others is only likely to be preserved in a species in which cooperation is necessary for survival." Humans, who generally require the help of others in thriving or raising children, are probably one such species.
