Yes, even them. It is all subconsciously.

Everyone believes they can't be tricked by those simple things.

same way placebo still works (to a degree) even when you know it's placebo

your subconcious is not logical, and no amount of conscious logic will fully defeat its influence

to think yourself immune is foolish and dangerous, that's when you allow it to work even better as you "logically" explain away every manipulation you were influenced by, and convince yourself you made a decision fully by yourself. The danger gets even hotter when it comes to political propaganda that uses the exact same tricks as marketing

that's the important caveat:

it does NOT work on everyone, but that's irrelevant.

if it works on even 1% of people, but has zero effect on everyone else, companies would still use it everywhere anyways.

a 1% difference over even just a couple thousand customers adds up over time.

so, no, it doesn't work on everyone, and it doesn't have to.

it just has to work on some people, and not deter any more people than it works on.

if anyone wonders when it does and does not work: like most of these psych-tricks the effect mostly disappears when you point it out to people or otherwise make them actively think about what they're buying.

same for the change-the-layout-of-the-store-all-the-time thing: doesn't work on all people, doesn't have to.

It actually works on smart people too.
