“There’s a theory in the sibling psychological literature called “deidentification,” which finds that siblings aren’t so much choosing their own identity as choosing what not to be in response to who their siblings are. In The Bin Ladens, Steve Coll describes the necessarily complicated dynamics that result when one father has 54 children. Most of the Bin Laden siblings grew up to embrace the entree to the West the father’s money gave them. In this psychological portrait, you could say that Osama Bin Laden, who made it his mission to destroy the United States, where many of his siblings were educated, lived, and did business, demonstrated the ultimate, homicidal case of deidentification.”
