I am currently debating the issue of allowing gay couples to adopt children. My opposition is rebutting any studies that show such children grow up to be perfectly happy and balanced by saying it is "merely social science" and thus, "easy to dismiss as not proper science, all surveys and meaningless statistics".
I need some concrete examples of how social science has changed the world, to back up my vague assertion that social science pretty much defines politics/education/law/the economy.
Any offers?
