Horrifying how this study was permitted to exist at the expense of the adopted children and adoptive parents. Nature vs Nurture was a hot topic at the time of the time of these adoptions. I adopted because I believed in Nurture and thought that were too many children that needed homes rather than have more babies biologically. Adoptive parents need all the information possible about their adopted child to help them grow in a healthy way. The secretiveness in the adoptions and withholding information was unconscionable. I'm glad it was exposed.
