Who decides what we believe?

Do the masses really decide what they want? Or do they merely borrow ideas from the people around them?

Trends go wild, videos go viral, fashion comes in–and goes out even faster, investors flock, people panic.

Have you ever found yourself agreeing with a position, changing your opinion, or believing something is beautiful or ugly because the mainstream has dictated it be so?

Who decides that dress is beautiful? Who decides the width of the lapels? Better yet, why do we all agree when somebody tells us that it's just so?

Should we trust the group, or be wary of group-think? Do the masses know best, or do they know at all? Are they simply following what those around them do for ease? Or is it for some level of tacit approval?
