You take this wayyyyy too seriously. Everyone is different. So not all kids will be manipulated that easily. In fact, I din't think there should be experts on child behavior. The personalities of children are so different and so many children are in the world. The experts seem like they forget that children have a brain and feelings and thoughts just like them selves. A lot of it depends on the wealth of their family. If they're poor and their parents don't have much to offer at all besides food, water, and shelter then they could grow up to start playing games like CoD, Battlefield, etc if they would be able to afford it. And their parents didn't really teach them much about right from wrong. The children that have a nice life in the suburbs or on a farm or in an apartment might start getting these games from ages 6-13, but they're parents teach them to read the bible and teach them right from wrong. The rich families could have a 5 year old wanting CoD and their parents really din't care what they do and buy all the CoD games for them and the kids grow up and not know much about right from wrong. Not really every living condition for children. There's many more. The biggest thing though is the child's mind.
