A weakness of institutionalisation studies?

-Romanian orphan studies are socially sensitive as the results show that the late-adopted children typically have poorer developmental outcomes. -These results have been published while the children have been growing up, meaning that the teachers, parents and anyone who knew them may have loweered their expections and treated them differently. This might have even created a self-fulfilling prophecy -On the other hand, much has been learned from the Romanian orphan studies that might benefit future institutionalised and potentially institutionalised children. -Though some may argue the publishing the results has done harm, it has done more good than harmm as it has allowed for institutions to progress and as well as psychologists to understands the effects of deprivation with early development. However due to the lack of external validity, it has to be applied with caution.
