Conservatives Seize On Hugely Flawed Study About Same-Sex Parents | ThinkProgress

Although dating to Febraury, Sullins research is important to note as he has in the past defended the Regnerus study, which is in the news again.  What it boils down to, "Conservatives praise these studies for their large samples, eagerly highlighting their negative results while ignore the distortions required to arrive at them."

Think of this as a precursor of what is to come.

Conservatives are excitedly promoting a new study that supposedly reveals negative outcomes for the children of same-sex parents. Like the infamously flawed Mark Regnerus study rushed out two years ago, the new study seems timed to impact the Supreme Court’s upcoming consideration of marriage equality for same-sex couples. It suffers, however, from some of the same flaws and biases as Regnerus’ study, and doesn’t actually support the argument against marriage equality that it tries to make.

The new study comes from Donald Paul Sullins, a Catholic priest and sociology professor at Catholic University of America. Sullins is a fellow of the Marriage and Religion Research Institute, a project of the anti-LGBT Family Research Council, and a Fourth Degree member of the Knights of Columbus, which has funneled millions of dollars into fighting marriage equality over the past decade. In 2010, he co-wrote a study suggesting that female homosexuality was somehow connected to growing up in a broken home, and when he has written about same-sex marriage, he uses scare quotes around the word “marriage.”

Sullins conducted an analysis of data from the National Health Interview Survey (NHIS) that had been collected from 1997-2013. He concluded that information about the 512 same-sex parents identified in the study demonstrates that their children have more emotional problems compared to couples raised by their biological different-sex couples. That these children fare worse, he concludes, “justifies social and policy concerns about differences between family structures, including between opposite-sex and same-sex families.” In other words, same-sex couples should not be allowed to marry because they make inferior parents.

One of the first major flaws, however, is the fact that Sullins has no information about whether the same-sex couples were actually married.  As he notes, “Almost all opposite-sex parents who are raising joint biological offspring are in intact marriages, but very few, if any, same-sex parents were married during the period under observation.” The same-sex couples were instead defined as “those persons whose reported spouse or cohabiting partner was of the same sex as themselves.” No conclusions can actually be drawn about the impacts of legalizing same-sex marriage because the study, by its own admission, collected no data about same-sex marriage or its effect on children.

Regnerus himself provides an overview of the research.  In his attempt to defend it, however, he in turn reveals that it also has the very same flaws as his own study. In particular, the NHIS similarly contains no information about family formation. Sullins notes that many of the children had a biological connection to one of the same-sex parents, but it’s unknown if these are from prior relationships, which would suggest their negative outcomes are related to a broken home instead of having two parents of the same sex. Regnerus used the same conflation; only two of the children in his study were actually raised from birth by same-sex couples and they did not exhibit the same negative outcomes as those children who had parents that separated before one entered a same-sex relationship. Incidentally, Sullins has likewise defended Regenerus’ conclusions about the supposed  inferiority “gay and lesbian families,” ignoring the significance of this flawed conflation.
