 :::::Not quite. What comparative advantage really means is that in the context of division of labor it can make sense that someone does something he's actually worse at than someone else. Think of an old hunter who due to his age has become very poor at hunting but is still fairly good at mending bows and making arrows. It makes sense that the younger hunters specialize completely on hunting and let him do all the bow-mending and arrow-making in exchange for meat, even though they'd be faster at it, they'll still hunt more this way. So, basically, even if someone is not very good at anything, there's still a place for him in a division of labor system, contrary to the supposed ""Social Darwinist"" approach, and the narrative of the article. And if Axelrod uses the words cooperation and defection in a very special way, then this should be explained in the article, the cooperation Wikipedia article to which the word is linked in its first instance does not indicate any such special use.—  "
