Reposting, from here Just because.
Are adoptees who don't feel especially curious about their biological heritage suffering from low IQ's? Are they unnatural, brainwashed, shut down, or paralyzed by feelings of abandonment?
No. They're not.
They say curiosity is a sign of intelligence. That may be so. I know something else that is a sign of intelligence, the ability to look outside your own experience. The ability to learn new tricks.
There are many, many people who just aren't that curious about their heritage. Some of them need only talk with their parents or visit an aunt or uncle to learn about it. Some can easily hit Ancestry.com or a local library and find all sorts of family background and info. But, they just aren't all that interested, not that curious. Does this make them stupid? Of course not.
I know some will say, well, that's because they can, they know who their real parents are. To that I say, so what? Some adoptees feel like their adopted parents are their real parents, end of story. They feel and see themselves no differently than other people. Why should they be held to a higher standard than everyone else?
Curiosity about circumstances of birth and relinquishment is not surprising, but it isn't a reflection of intelligence. A person uninterested in "what happened" or who their immediate or distant biological relatives are could very well be curious about many other things, things that are far more important to them personally.
It seems to me that when it comes to curiosity about one's own circumstance of adoption and/or heritage, it can vary in degree. It can be nonexistent. It can be mild. It can be all-consuming. It can be both mild and all-consuming from one day to the next, from one hour to the next. It can be stifled due to outside influences. Lack of curiosity can remain in spite of outside encouragement to be curious. It can be there when we're young and vanish when we're older. It can be nonexistent in our youth and then overcome us when we have children.
I've read harsh judgements on adoptees searching for such a frivolous reason as "just being curious". I have had to question myself about this, if simple curiosity was a good enough reason to potentially disrupt the lives of others. It's a big fat no-no in some circles to search out of curiosity as opposed to searching to find and embrace our real parents and/or a new or different family.
For some adoptees just seeing a picture of their parents would suffice. For others, an explanation for having been adopted and a picture, never really feeling the need to actually meet anyone. There are adoptees who want full blown familial relationships with their biological relatives. None of it is wrong or an indication of intelligence or necessarily a reflection on anyone else. To say so, at best, is not very nice. At worst, it's not very smart.
