It's easily seen in this context, because of the material covered and the fact that they don't try very hard to be subtle about it. In other contexts the same set of tricks may slip past, unless you have an example to pattern match to (not a whole new habit). Immunization using a weak form of memetic attack you're primed to defend against.
The literature on the ability of people to learn about tricks and then resists them suggests that it's hard. Transfer is hard.
