Scientists have finally discovered why your male boss behaves like a chest-beating chimpanzee: it's in his genes. Aussie researchers interviewed hundreds of managers and employees, and found that, like animals, bosses assert their authority with visuals and behavior. (Like monkeys who flaunt brightly colored body parts, male managers tend to pair bright shirts or ties with dark suits; they also have bigger chairs, interrupt more, and use confusing jargon to assert their place in the office hierarchy. "Groups were territorial in the past because it helped them survive...But it is surprising how many... workers are still very tribal in their behavior," says professor Jeffrey Braithwaite. The research focused on men, but Braithwaite says that among female managers, some become "alpha females" to compete with the men while others adopt "a more team-oriented style." [The Independent]
