Here's an example. What if Google decided that when you pull down for notifications on android, items originating from DoubleClick should be prioritized to the top, regardless of user settings? A lot of people who have apps that generate advert-ifications wouldn't immediately notice the difference but the effect would begin to work in their brains as that consumption impulse is triggered more and more often.
Or what if they decided that same thing for the lock screen notifications? Eventually you're fending off consumption impulses everytime you touch your phone.
These are patterns I trust independent users, like bloggers and columnists, enthusiasts, those sorts, to keep me informed about. I remember hearing about the search engine nuking years ago when it actually was committed. That sort of media is in my eyes, a decent way to inform people that they need to mentally condition themselves to subvert the patterns.
But many never become aware of these things, and of course those are the people usually more vulnerable to the effects of psychological conditioning in the first place.
I'd love to hear some moonshots about how to safely and fairly try and regulate something like design.
