Adoptive parents may be less likely to consider the possibility that they are doing something wrong, and blame the child's heredity. The parents may even unfavorably compare their adopted child with a near-perfect, genetically-related "fantasy" child. This enables them to blame ordinary problems which all parents face on their child's supposedly "defective" genes. Thus, while non-adoptive parents are focused on nurture, some adoptive parents are solely focused on nature (i.e. heredity) instead. This results in what could have been an easily resolved problem, going unresolved in families with adopted children, possibly accompanied by child abuse.
Most open adoptions lie somewhere in the middle, according to Grotevant and McRoy, exchanging letters, pictures, and phone calls, and having face-to-face meetings once or twice a year. Whatever their situation, many families report that relatives and friends condemn openness, and voice fears that the arrangement will make the birth parent want the child back.
