When people encounter ambiguous evidence, this bias can potentially result in each of them interpreting it as in support of their existing attitudes, widening rather than narrowing the disagreement between them. The study of group polarization can be traced back to an unpublished 1961 Master's thesis by MIT student James Stoner, who observed the so-called "risky shift". , One study analyzed over 30,000 tweets on Twitter regarding the shooting of George Tiller, a late term abortion doctor, where the tweets analyzed were conversations among pro-life and pro-choice advocates post shooting. , Group polarization and choice shifts are similar in many ways; however, they differ in one distinct way.  Research has indicated that informational influence is more likely with intellective issues, a group goal of making correct decision, task-oriented group members, and private responses. Moreover, computer-mediated discussions often fail to result in a group consensus, or lead to less satisfaction with the consensus that was reached, compared to groups operating in a natural environment. , Informational influence, or persuasive arguments theory, has also been used to explain group polarization, and is most recognized by psychologists today. , In a study conducted by Sia et al. Participants were then asked to estimate the probability that a certain choice would be of benefit or risk to the individual being discussed. It helps account for many terrible things, including terrorism, stoning, and “mobbing” in … According to the social comparison interpretation, group polarization occurs as a result of individuals' desire to gain acceptance and be perceived in a favorable way by their group. In doing so, individuals support the group's beliefs while still presenting themselves as admirable group "leaders".  When people had read both the research that supported their views and the research that did not, they tended to hold their original attitudes more strongly than before they received that information. The persuasive arguments interpretation holds that individuals become more convinced of their views when they hear novel arguments in support of their position. As long as the group of individuals begins with the same fundamental opinion on the topic and a consistent dialogue is kept going, group polarization can occur. found individual preferences to be irrelevant; it is differences of opinion which will cause the shift. Also, Moscovici et al. Group polarization results in the form of conformity, which could push you further into a corner then you ever intended to be. Stoner, J. These more extreme decisions are towards greater risk if individuals' initial tendencies are to be risky and towards greater caution if individuals' initial tendencies are to be cautious. The discovery of the risky shift was considered surprising and counter-intuitive, especially since earlier work in the 1920s and 1930s by Allport and other researchers suggested that individuals made more extreme decisions than did groups… , Research has suggested that well-established groups suffer less from polarization, as do groups discussing problems that are well known to them. Thus, on decisions in which group members have, on the average, a moderate proclivity in a given direction, group discussion results in a more extreme average proclivity in the same direction. ____The chances are 1 in 10 that the company will prove financially sound. Overall, the results suggest that not only may group polarization not be as prevalent as previous studies suggest, but group theories, in general, may not be simply transferable when seen in a computer-related discussion. In‐group polarization does not affect gender attitudes, however. According to the idea of group polarization, if an individual holds an opinion about a topic, that opinion will likely be enhanced after a discussion on the topic with a group. A split into opposing factions that fail to reach an agreement b. A. F. (1961). Daniel Isenberg's 1986 meta-analysis of the data gathered by both the persuasive argument and social comparison camps succeeded, in large part, in answering the questions about predominant mechanisms. discussion leads a group to adopt attitudes or actions that are more extreme than the initial attitudes or actions of the individual group members Of individual and group decisions involving risk an empirical test of the penalty!
