It is putting the images and notions in peoples heads, anything you are exposed to will seem familiar when you see it again and repeat exposure amplifies this effect.

DS have been using this same technique for their means, things such as emotional displays/behavior and child-like psychology being presented over and over again in entertainment until they basically become the accepted 'normal' due to familiarity through repeated exposure (someone from the 80's seeing people displaying the kind of emotional behavior and psychology that is seen today and is deemed 'normal' would have them look at them like they were mental patients)

However the very same technique can be used by the good guys, so that when things become public and exposed, people will find them easier to digest because they involve notions and images that their brains have been exposed to previously and that are some what familiar.

The 'cold-pitch' is rarely used in sales because it is so unlikely to be successful, telling people the truth and getting them to accept it would be even worse, however if they have already been eased into it through previous exposure, it becomes a pill that is much easier to swallow, much like selling people something through referencing something they already know/own/use being easier than convincing them they need something they have no familiarity with.....

It's not the context, it's the notions, images being presented to create a sense of familiarity with them for when they become real...

I think it some show for tv watchers
