Actually, Dan, there are well-regarded academic studies that show that groups 
that contain women are smarter than all-male groups, regardless of the relative 
intelligence of the group members.  Surprising, perhaps, but true.  Here is a 
pointer to a discussion of one of them:

There are also numerous studies, of various types, that show that  more diverse 
groups make better decisions and/or perform better than less diverse groups.  
Here is a description of one such study:

So, as illogical as these statements may seem on the surface, they are 
well-established facts.  Both of the articles I've sited give some insight into 
why this is true.
