ABSTRACT
Risk perception is the perceived judgment by an individual, group of people, or society about the attributes, condition, and severity of a risk. Decision makers and risk analysts do not always react with perfect rationality to prospects of loss and gain in the presence of risk because individual perception impacts decisions. If every individual perceived the world around him or her in the same manner, there would be no difficulty in assessing the acceptability of a particular risk situation or event (Doro-on 2011). In the real world, people often fail to predict reality very clearly. Risk issues occur in different cases, in which experts and authors are often interested, but none is completely organized and finely documented. They are often surrounded by a large degree of uncertainty resulting from such diverse causes as limited knowledge and restricted measurement capabilities (Doro-on 2011). Compounding these limitations is the complexity of the problem, not just based on the multiplicity of risk pathways but also because risk does not exist by itself (Doro-on 2011). It is only one of many problems that must be considered as simply one factor in a morass of benefits and costs, which can be direct and indirect, that surround any public decision problem (Doro-on 2011).
