It is routinely asserted in courts, journals and the media that it makes ??no difference? whether a child has a mother and a father, two fathers, or two mothers. Reference is often made to social-scientific studies that
are claimed to have ??demonstrated? this.
An objective analysis, however, demonstrates that there is no basis for this assertion. The studies on which such claims are based are all gravely deficient.
Robert Lerner, Ph.D., and Althea Nagai, Ph.D., professionals in the field of quantitative analysis, evaluated 49 empirical studies on same-sex (or homosexual) parenting.
The evaluation looks at how each study carries out six key research tasks: (1) formulating a hypothesis and research design; (2) controlling for unrelated effects; (3) measuring concepts (bias, reliability and validity); (4) sampling; (5) statistical testing; and (6) addressing the problem of false negatives (statistical power).
Each chapter of the evaluation describes and evaluates how the studies utilized one of these research steps. Along the way, Lerner and Nagai offer pointers for how future studies can be more competently done.
