I'm currently arguing with a Chrsitian about whether same sex couples are as good parents as hetero couples. His critique of the first batch of studies that I threw at him (I'm a lay person in this field) was
"It is very important that people not be allowed to self report, nor drop out of the study, and best of all when they don't know they are being counted. Now, admittedly, this is kind of hard, but that is how you get quality."
Sounds reasonable to me. Anyone know of good studies that avoid theses traps, or at least some or most of them?
