You probably simply never noticed. Maybe the grocery chain you buy at. Maybe a particularly flashy packaging of a food item in said grocery store. Maybe an outrageous fun sex toy you saw in porn. Maybe you’re subscribed to a Patreon somewhere. Maybe you have a t-shirt of your favorite show. Do you really make all these decisions completely conscious of all advertising you saw before, making sure that you do not miss any better alternatives with worse advertising?

No person can think so much about all their decisions to spend money. No one can be so perfectly conscious of every single sensory input. Advertising works on everyone, you just don’t even notice when it works on you.
