Intelligence tests

I don't have much faith in intelligence tests. My definition of intelligence is successful adaption to new circumstances. Adaption and persistence determine your material success. How can you hope to test adaption, especially the social component in an hour long test?

Recently a friend of mine told me that his child's test score indicated his child being super intelligent but my friend didn't value the result much, although it was better than having an imbecile score. Our conclusion is that such tests mainly measure how much care the child was given by the parents. If parents have done a good job of parenting, I suspect any kid who does not have a mental condition will score highly in those tests.
