This is similar to social conformity in which it is perceived that the best
option is the one that most people agree with. (Voting context)
Basically, the problem of doing the thing that most do will not satisfy
everyone. This is because, of course, there are outliers in the
population. For instance, having loud and noisy parties would certainly
hurt an autistic person like me a lot, as I am pretty sensitive to loud
noises and will actually feel mental pain. However, because it’s still
utilitarianly better to benefit more people, it often leads to a bit of
controversy. Alternative example: Most people in HK speak Chinese more,
so I am a rare outlier, but, naturally, people would assume I mainly
speak Chinese at first glance.
