Until recently, a Catholics in Alliance for the Common Good study of abortion data claimed that increased spending on welfare programs results in substantial reductions in state abortion rates but many pro-life laws do not. However, the study’s results have been revised following the discovery that incorrect abortion data was used and after criticism from a professor that the group’s conclusions did not follow from the data.
The old version of the report was removed from the site in November 2008 after critics pointed out problems with the study.
The feedback of Michael J. New, an assistant professor of political science at the University of Alabama, was acknowledged in the new version of the report. Writing at the web site MoralAccountability.com, New said that the authors of the study discovered that they had used incorrect abortion data for the years following 1997.
“The new version provides evidence that welfare policy has no more than a marginal effect on the incidence of abortion,” he argued. “In fact, the new regression results indicate that none of the three welfare policies which the authors previously argued were effective tools for reducing the incidence of abortion have a substantial abortion reducing effect.”
In an essay at MoralAccountability.com, New accused Catholics in Alliance for the Common Good of misleading the public and referred to “plenty of peer reviewed studies” which find that public funding restrictions and parental involvement laws reduce the incident of abortion.
He claimed the study had a “substantial impact” on the pro-life debate in the 2008 Presidential election and gave “intellectual legitimacy” to those such as Doug Kmiec and Nicholas Cafardi who argued that pro-life voters should vote for Democrats to advance the pro-life cause.
So, now we have it. I wonder if any will admit that they were wrong. Probably not.
