why can adoption studies provide support for genetic explanation?
adoptees are more likely to have criminal records if their biological parents had criminal records
what is a limitation of adoption studies?
(what’s it low in?)
low reliability
why are adoption studies low in reliability?
gottfredson and hirschi

what is another limitation of adoption studies?
(what is the difference?)
difference in environment
why is difference in environment a limitation of adoption studies?
many children are NOT adopted from birth
meaning they remain with their biological parent(s)/family for some time
once they are adopted are often placed in environments like those of their birth families, with families of the same: . class
. ethnicity
. locality
these similar environments can produce similar criminal behaviour, can explain its not just genetics
