Previous research with face-to-face groups found that majority-minority theory was a better predictor of argument patterns between Israelis and Palestinians than cultural codes theory (D. G. Ellis & I. Maoz, 2002; I. Maoz & D. G. Ellis, 2001). But, because of the difficulties of organizing face-to-face contacts between Israelis and Palestinians (e.g., security, transportation, check points), computer-mediated communication has taken on increased significance. This paper builds on previous research pertaining to argument between Israeli Jews and Palestinians and extends that work by investigating the effects of communication technologies on argument interactions between these two groups. The most notable finding was the absence of complex argumentative structures that are typically associated with conflict resolution.
