Does anyone know anything about the experiment Anna Freud did, with others, at Yale, on the nature/nurture idea, involving identical twins and triplets taken from their mothers (see the film identical strangers about triplet Jewish boys in USA) at the Jewish familty centre, splitting them up, which ruined the lives of those children. She fled thereafter to Switzerland. The results are in a vault at Yale, not to be opened till 2066. ????? Anyone know???
