Extract

In my comments on Townsend's detailed critique of Sulloway's (1996) book, I want to make two general points about birth order research. The first is that several authors—including Ernst and Angst (1983), who are extensively quoted by Townsend—have concluded that the effects of birth order on adult personality and behavior are either completely nonexistent or else so negligible as to be useless to science. I agree that the methodology of birth order studies is often flawed, and that many, if not most, of their findings are probably irreproducible. However, an assertion that birth order has no effect on adult behavior would be as extreme in its way as the assertion that birth order's effect on behavior is decisive. My own research demonstrates that a categorical dismissal of any and all birth order effects is not only premature but demonstrably erroneous.
