Are you sure about that? There are a whole lot of stimuli-responses that are extremely similar across... very nearly all humans, and that is without particularly trying. Sure, it may not be rotating a spiral in front of them to make them unceasingly obedient to all of your commands, but advertising does see real results in getting people to do things they do not actually benefit from nor have a pre-existing interest in. And again, that is trusting your mind-control genetics to evolution. A proper effort dedicated to creating a mind prone to reliable responses to specific stimuli... it could go quite far.
