“…Prior work shows that factors such as age and gender can indicate similarity with others, and that similarity leads to affiliative behavior (e.g., McPherson, Smith-Lovin, and Cook 2001;Brown, Grzeskowiak, and Dev 2009;Naylor, Lamberton, and West 2012). For example, actual or inferred similarity between two people (e.g., a shared birthday) can enhance compliance with each other's requests (Burger et al 2004), make online reviews more persuasive (Naylor, Lamberton, and Norton 2011), and increase the perceived social connection between two individuals (Jiang, Hoegg, Dahl, and Chattopadhyay 2010). Taken together, this literature suggests that when a consumer contributes WOM after an individual who is personally similar to her, the consumer should affiliate with this individual.…”
