Something very similar happens at many Internet dating sites. Attractive women get more emails than they can answer. The men, who find that many of their emails go unanswered, react by sending more emails. Moreover, these emails become less informative, because the men submitting them are less likely to study the information contained in each woman’s profile and how best to approach her. The women in turn reply to a smaller and smaller percentage of the messages they get, and the men respond by sending even more, and even more superficial, messages.
