My advertising professor told us the opposite, he straight up told his students that the best sales tactics is to evoke emotional responses like fear and mental anguish and to leverage that to your benefit, including with with lies of omission and unsubstantiated claims about what you are selling. Sure you don't HAVE to do those things, but then you won't make nearly as much money doing only slightly less soul crushing advertising work. Just like being a good politician doesn't usually get you nearly as far as being a bad and corrupt politician willing to lie straight to people's faces.
