Yes, for the general population. Otherwise, companies will stop the psychological pricing. Same with corporate snooping to see our shopping and grocery habits and then send us with targeted ads.
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.
