homophily

Examples of homophily in the following topics:

• Homophily models

  • The result in the section above seems to support homophily (which we can see by looking at where the deviations from independence occur.
  • So, although the model of constant homophily does not predict individual's ties at all well, there is a notable overall homophily effect.
  • This model fits the data much better (R-square = .269, with p < .000) than the constant homophily model.
  • Constant Homophily blockmodel of differences in group tie density
  • Variable homophily blockmodel of differences in group tie density

• Introduction to explaining the relations among actors in a network

  • This "homophily" hypothesis is at the core of many theories of differentiation, solidarity, and conflict.
  • Several of the models below explore homophily and closeness to predict whether actors have ties, or are close to one another.

• Hypotheses about relations within/between groups

  • The notion that similarity (or homophily) increases the probability of the formation of social ties is central to most sociological theories.
  • The homophily hypothesis can be read to be making a prediction about social networks.
  • But the difference does not support homophily -- it suggest just the opposite; ties between actors who share the attribute of not representing workers are less likely than random, rather than more likely.
  • Perhaps our result does not support homophily theory because the group "non-worker" is not really as social group at all -- just a residual collection of diverse interests.
  • We note that all three diagonal cells (that is, ties within groups) now display homophily -- greater than random density.

• Challenges to Achieving Organizational Diversity

  • Another challenge is related to a social behavior called homophily—the tendency of individuals to associate with others who are similar to them.

• Summary

  • Much of the focus here is on how attributes may pattern relations (e.g. homophily), or how network closeness of distance may affect similarity of attributes (or vice versa).

• Diversity Bias

  • This bias relies on a tendency toward homophily (the tendency of similar types of individuals to form groups), as in-group favoritism is the tendency for individuals to provide preferential treatment to those of a similar perspective or disposition.

• Hypotheses about similarity and distance

  • The homophily hypothesis is often thought of in categorical terms: is there a tendency for actors who are of the same "type" to be adjacent (or close) to one another in the network?
