Observational studies of human conversations in relaxed social setting
s suggest that these consist predominantly of exchanges of social info
rmation (mostly concerning personal relationships and experiences). Mo
st of these exchanges involve information about the speaker or third p
arties, and very few involve critical comments or the soliciting or gi
ving of advice. Although a policing function may still be important (e
.g., for controlling social cheats), it seems that this does not often
involve overt criticism of other individuals' behavior. The few signi
ficant differences between the sexes in the proportion of conversation
time devoted to particular topics are interpreted as reflecting femal
es' concerns with networking and males' concerns with self-display in
what amount to a conventional mating lek.
