There's a big difference between groups gauging each others' attitudes and individuals communicating specific decisions. Humans instinctively try to be harmonious with their group, and the group not responding to something negative communicates that this group doesn't care about it enough to respond to it. Furthermore, group attitude influencing individual behavior is a well-known facet of humanity. This concept is the foundation of television and other types of advertising.
