In the past, forced or arranged marriages meant that socially inept, unattractive men did not have to acquire social skills in order to find a long-term love interest. Today, men must be able to turn on the charm if they want to find a partner. Those men who have difficulty flirting, or are unable to impress the opposite sex may remain single because their social skills have not evolved to meet today’s societal demands. So says Menelaos Apostolou of the University of Nicosia in Cyprus in a study in Springer’s journal Evolutionary Psychological Science. Apostolou analyzed more than 6,700 comments left by men on the popular social news and media aggregation internet site Reddit.
