The older we become the more we tend to be influenced by our experience and set in our ways.
Children on the other hand have a much less tainted view of things. They tend to see things from a totally different perspective than adults.
Because children have fewer assumptions (if any) and are less inhibited they tend to give a more honest and black and white view of the world.
Often they'll give us a totally left of field response without any concern for convention.
SO ASK A KID!
Mind you you'll need to phrase things in a simpler way - which in it's own right is a good thing!
"Adults are always asking little kids what they want to be when they grow up because they're looking for ideas"
