"Insanity in individuals is something rare - but in groups, parties, nations and epochs, it is the rule"

This quote by Friedrich Nietzsche speaks with the power of groupthink and how it can lead to unreasonable and illogical choices. He recommends that when individuals are alone, they are more likely to make logical decisions, however when they belong to a group, they are more likely to be affected by the group's collective opinion. This can result in a scenario where the group's decisions are not based upon reasoning or factor, however on feeling and impulse. This can result in a circumstance where the group's choices are not in the best interest of the people or the group as a whole. Nietzsche's quote is an alerting to be familiar with the power of groupthink and to be conscious of the decisions we make when we become part of a group.
