According to a June 25, 2007 article from The New York Times, a recent study indicates that first-born children tend to have higher I.Q.'s than their siblings. Educators are uncertain whether this phenomenon stems from biological or environmental factors. Those who contend social dynamics play a larger part believe that the oldest sibling's perceived role within the family, as well as having the opportunity to tutor younger siblings, fosters the development of a higher I.Q. Experts warn parents not to place too much stock in their children's scores, because I.Q. tests measure only a narrow set of specific skills.
