Risk awareness, an indispensable point in risk management, has been applied to many empirical studies such as health surveillance, natural disasters and financial collapses. Theoretically, if risk awareness had been properly examined, pity, losses and dangers could be avoided in a large number of circumstances. In practice, however, as many fiascos indicate, selecting appropriate ideas in advance can be much more difficult than understanding the situation later. While improvements could be made from a scientific perspective by modifying quantitative models, the behavioral barriers deeply rooted in this process limit its effectiveness. The rest of the piece will attempt to illustrate the hidden effects of human behaviors on risk awareness during the 2008 financial crisis. This catastrophe once again highlights that, although objective analysis and technical refinements could have brought improvements earlier, they are the factors behavioral and psychological issues that deserve greater attention. The financial crisis of 2008 seemed to come suddenly and primarily shocked the whole world, but it was soon concluded by experts as a consequence of systemic risk. (Federal Reserve Bank of Atlanta, 2009) There are three perspectives to characterize this risk, first, universal losses triggered by a single event (IBS, 2001), second, the revelation of hidden correlations between institutions financial (Kaufman and Scott, 2003), and third, the occurrence of a less optimal transition from one equilibrium to another (Hendricks, 2009). This finding also drew attention to previously hidden risks and therefore increased the perception of investment risks on an individual basis (Roszkowski and Davey, 2010). Meanwhile, for regulators and organizations, the focus shifts to correlations between counterparties from controlling risk as individuals, as can be demonstrated by the recent Basel regulations.
