"To a considerable degree, antiabortion activists are able to take advantage of the fact that the general public and most policymakers do not know what constitutes “good science” (related article, November 2005, page 1). To defend their positions, these activists often cite studies that have serious methodological flaws or draw inappropriate conclusions from more rigorous studies. Admittedly, the body of sound research in this area is relatively sparse because establishing or conclusively disproving a causal relationship between abortion and subsequent behavior is an extremely difficult proposition. Still, it is fair to say that neither the weight of the scientific evidence to date nor the observable reality of 33 years of legal abortion in the United States comports with the idea that having an abortion is any more dangerous to a woman’s long-term mental health than delivering and parenting a child that she did not intend to have or placing a baby for adoption."
