Herd mentality describes how people are influenced by their peers to adopt certain behaviors, follow trends, and/or purchase items. Examples of the herd mentality include the early adopters of high technology products such as cell phones and iPods, as well as stock market trends, fashions in apparel, cars, home décor, etc. Social psychologists study the related topics of group intelligence, crowd wisdom, and decentralized decision making.

People in these herds are broken up into two groups, explains Friedrich Nietzsche, a philosopher who coined the phrase. One lended itself to the religious points of views- their beliefs and how those dictated their actions- while the other lended itself to influence by the media- more liberal and based upon what others perceive as 'right' (following trends, social norms, etc.).

Herd mentality results in the slow and gradual decay of not just our tiny circle of society, but the whole of humanity as we see it today. And to quote Ms. Rand,

"Throughout the centuries there were men who took first steps down new roads armed with nothing but their own vision."
