“…Studies have focused on individuals' trust in and use of e-commerce (Gefen et al, 2003;Tan & Thoen, 2002) or in their choice of automation or human control (Muir, 1994). This work generally suggests that trust and perceived fairness emanate from individuals' familiarity or comfort with the medium (Wiechmann & Ryan, 2003), perceptions of systems reliability (Hertzum, Andersen, Andersen, & Hansen, 2002;Muir, 1994), and the control mechanisms put in place to guard against system deficiencies or operator self-interest (Gefen et al, 2003;Tan & Thoen, 2002). For example, Tan and Thoen developed a model of trust in electronic commerce that suggests that individuals will feel comfortable engaging in a transaction if trust in the other party and trust in control mechanisms exceed one's trust threshold, where lower trust thresholds are associated with a history of satisfactory and reliable transactions.…”
