According to Granovetter,the image is considered to be the forbidden triad. Each of the dots represent a person in a network. If one node has a tie to two other nodes, then each of those two individuals should possess some kind of relationship. In other words, if you are are friends with two individuals then there is likely to be a relationship of some sort between them. This is based off of the idea that people befriend people with like characteristics and these individuals will gravitate towards one another in a small social network.

Democratic elitism holds that democracy is limited in a large society, because in the end not everyone has an equal say. The theory of democratic elitism considers that the most power that the masses can and should have is the ability to regularly elect their representatives (thus, selecting the 'elite') to make the decisions for them, because the pluralist idea that everyone has a say is a folly and not truly realizable.

The Iron Law of Oligarchy states that all large organizations are ruled by elites. Small organizations can be ruled collectively, but most large organizations are hierarchical and are ruled by elites at the top.

"Social loafing" is the term used to describe an individuals tendency to do less group in a group then they would do if they were working alone. This is caused by free-riders who assume that someone else will complete the work that must be done. It is further impacted by the tendency for individuals to lessen their efforts in response to free-riders. Social loafing is more prominent in larger groups where individuals may become just another face in the crowd and may not be subject to individualized responsibilities.

The only correct answer is groupthink because it means the tendency of a group to become narrow in their ideas for the sake of harmony, despite if they make faulty decisions. In-group means the group a person psychologically identifies as being a part of and can typically share similar ideas, primary group means a group where the people create strong and lasting relationships, and caste system is a system where people are born into their social standing and stay in that class their entire life.

Hegemony is what happens when the ideology of a dominant group is able to influence the ideology of larger society. For instance, hegemony in the United States can be seen in the sociological focus on how the trade market and Wall Street are doing, despite there being other ways to measure the economy. Hegemony is not a conscious exertion of power of the dominant group to control others, but simply what happens when the interests and ideals of one group influence an entire society.

Sociology center on how humans interact with social settings. It is interested in the opposite of human isolation. Although a sociologist might be interested in how intellect can be impacted by society, it does not study human intellect as a neurologist or psychologist might. Individualism is contrary to a concept sociologists because they are interested in groups/societies. Evolution does not fall within the definition of what a sociologist would study.
