In social psychology, group polarization refers to the tendency for a group to make decisions that are more extreme than the initial inclination of its members. 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. [1]
The differential group delay is the difference in propagation time between the two eigenmodes X and Y polarizations. Consider two eigenmodes that are the 0° and 90° linear polarization states. If the state of polarization of the input signal is the linear state at 45° between the two eigenmodes, the input signal is divided equally into the ...
By pairing two complementary polarizations, this scheme can immunize a system from polarization mismatches that would otherwise cause signal fade. Additionally, such diversity has proven valuable at radio and mobile communication base stations since it is less susceptible to the near random orientations of transmitting antennas. [1]
Since all members of the Group do not meet directly when this approach is used, they communicate by mail, thus eliminating the impact of the authority. This is the main feature of the method. Anonymity is a very important function of Delphi methods. Forecasters don't know each other. They exchanged ideas with complete anonymity. (ii) Feedback
In neurology, there is an established literature [5] about the innate propensity of the human brain to divide the world into us and them valence categories, where the exact membership of the in-group and out-group are socially contingent (hence vulnerable to the instruments of propaganda), and the intensity exists along a spectrum from mild to ...
Groupthink is sometimes stated to occur (more broadly) within natural groups within the community, for example to explain the lifelong different mindsets of those with differing political views (such as "conservatism" and "liberalism" in the U.S. political context [7] or the purported benefits of team work vs. work conducted in solitude). [8]
Polarization itself is typically understood as "a prominent division or conflict that forms between major groups in a society or political system and that is marked by the clustering and radicalisation of views and beliefs at two distant and antagonistic poles."
Ardener's 1975 muted group theory also posited that dominant group members formulate a "communication system that support their perception of the world and conceptualized it as the appropriate language for the rest of society". [3] Communication faculty Stanback and Pearce (1981) referred to these non-dominant groups as "subordinate social groups".
