Incest ? == 

 A paragraph of the Incest article leads the reader to this John Boyd Article. 

 Sometimes the word "incestuous" is also used metaphorically to describe other inappropriately close relationships, for example between an authority figure and a subordinate, or between people in the same profession or creative field. The term "incest group" is also common in high school, and denotes a group of friends that only date others within their group. Institutions such as churches, colleges, and sometimes whole nations can be described as incestuous when inappropriately close relationships, corrupt conflicts of interest and secret collusions occur inside the institution and especially within the institution's top echelons such as in cases John Boyd exposed in the Pentagon. 

 Please verify.
