Effects of initial tendency and real risk on choice shift
Article Abstract:
Studies in risk taking and decision making were undertaken to determine individual and group processes involved in choice selections. Group discussions can alter the choices of an individual's perception and acceptance of risk taking. The level of difficulty of the risk to be undertaken also influences group and later individual choices. The study concludes that additional research should be conducted on individual decision making which occurs prior any influence induced group discussion.
