Or how propaganda works.. repeat something enough times, and people will value it as much as
many people voicing the same opinion:
The studies found that an opinion is more likely to be assumed to be the majority opinion when multiple group members express their opinion. However, the study also showed that hearing one person express the same opinion multiple times had nearly the same effect on listener's perception of the opinion being popular as hearing multiple people state his/her opinion.
Ah, so advertising wins again!
