  1. Homophily refers to the tendency to recruit in the same category with a metric between 1 (recruited and recruits in the same category) and − 1 (recruited and recruits in a different category). Heckathorn suggests any value of homophily ≥ 0.3 as intermediate homophily and any value ≤ − 0.3 as strong heterophily
