Take for example research into AIDS. At first, all the studies focused on men. Only later was it discovered that while symptoms like pulmonary complications have been common in male carriers, symptoms in women have proved to be different. A consequence of this oversight was that it was more difficult to do early detection in women, and once the disease was discovered, death came faster than for men.
以愛滋病的研究為例，一開始都是以男性為研究對象，後來才發現，愛滋病的肺部併發症等癥候多發生在男性帶原者身上，女性帶原者的症狀並不同於男性，因而造成女性帶原者不易早期發現，而一旦罹病死亡速度較男性快的現象。
