Recently, text chat has become the mainstream in CMC(Computer-Mediated Communication), and it is used even for discussion to build consensus. In the case of CMC between strangers, anonymity is attracting attention as factor influencing communication. However, influence of anonymity on CMC between acquaintances has not been clarified. Therefore, with the aim of developing a new text chat system that supports discussion between acquaintances, we examine the influence of anonymity in text chat on consensus building between acquaintances. As a result of the experiment, in case of between acquaintances, there is a possibility that the time to consensus building become shorter in discussion by anonymity than in discussion by real name. Moreover, there is a possibility that discussion by anonymity is more efficient than discussion by real name.
