Your hypothesis is true, priming can affect human behavior in many different ways. Specifically pro-social behavior can be encouraged by simply displaying an image of a pair of eyes.
We examined the effect of an image of a pair of eyes on contributions
to an honesty box used to collect money for drinks in a university
coffee room. People paid nearly three times as much for their drinks
when eyes were displayed rather than a control image. This finding
provides the first evidence from a naturalistic setting of the
importance of cues of being watched, and hence reputational concerns,
on human cooperative behaviour.
Also in a similar study the following results are found.
We also found that
images of watching eyes reduced littering, although contrary to
previous findings this was only when there were larger numbers of
people around. With regard to our central aim, we found no evidence
that litter on the ground interacted non-additively with images of
eyes to induce increased littering behaviour. Our data therefore
support the hypothesis that images of eyes induce more pro-social
behaviour, independent of local norms. This finding has positive
implications for the application of eye images in combating
