MARK REGNERUS: Is Same-Sex Parenting Better for Kids? The New Australian Study Can’t Tell Us.

Until social scientists decide to do the difficult, expensive work of locating same-sex attracted parents (however defined) through random, population-based sampling strategies—preferably ones that do not “give away” the primary research question(s) up front, as ACHESS did—we simply cannot know whether claims like “no differences” or “happier and healthier than” are true, valid, and on target. Why? Because this non-random sample reflects those who actively pursued participating in the study, personal and political motivations included. In such a charged environment, the public—including judges and media—would do well to demand better-quality research designs, not just results they approve of. . . .

Skepticism about the ACHESS sample is all the more reason to do a random study that doesn’t advertise its intentions beforehand. That’s exactly why the survey I oversaw, the New Family Structures Study (NFSS), elected to talk to the children after they had grown up, to skip the parents entirely to ensure a more independent assessment, not to broadcast our key research questions in the title or initial screener questionnaire, and to locate participants randomly in a large population-based sample. If you’ve been paying attention, however, you’ll know that my NFSS studies [PDFs]—which mapped 248 respondents who told us their mother or father had been in a same-sex relationship—came to rather different conclusions than the ACHESS study has.
