The older brother effect (which is the best bit of research we have I think in this area of causation) is fascinating. I would love to see how younger siblings of single births (i.e. just one child in gestation) compare to younger siblings of multiple births (i.e. twins etc) as that would help us see whether the hormonal effect in the womb theory had some validity.
