What do the studies say about same-sex parenting?
Two recent reviews of the available social science literature with respect to children raised by two parents of the same sex find significant flaws in research methodology, highlighting the need for additional research regarding the impact of same-sex parenting on child development.
Prof. Steven Nock
Professor Nock is a professor of sociology at the University of Virginia. In his affidavit filed with the Ontario Superior Court in Halpern v. Attorney General, Professor Nock explains the principles of social science research methodology, and then critiques a series of studies which have dealt with the question of same-sex parenting. Based on his review of the studies, Professor Nock concludes "1) all of the articles I reviewed contained at least one fatal flaw of design or execution; and 2) not a single one of those studies was conducted according to general accepted standards of scientific research."
