风险感知是一个涉及决策的过程，这是一个非常个人化的过程，它是基于一个人在一生中与其他因素一起建立的参照系。过去十年进行的几项研究表明，当决策与安全和健康有关时，最紧迫的威胁没有得到考虑。根据David(2012)，这被称为风险感知文献中的缺口(Dorfman et al, 2012)。风险认知的差异似乎是由于疏忽或无知造成的，但心理学家和研究人员断言，这是一种自然的能力，除了考虑事实之外，还会考虑各种因素。
风险感知是一种高度主观的评估，评估所定义的行动类型发生的可能性，并确定与后果相关的关注。为了感知风险，对可能性的评估是必不可少的。这伴随着负面结果将带来的影响。这是风险感知所必需的。风险感知高于个体，认为它是一种文化和社会的建构，反映了价值观、历史、符号和意识形态(Jorion, 2010)。它遵循着人类社会存在的特殊性和变异性，不应假设在不同的语境中，对具有相同身份的工具进行评级和评分具有相同的意义。Adams(1995)认为，任何风险理论的出发点都是每个人在承担风险时都应该有自己的意愿。在20世纪60年代，风险感知作为一个重要的概念出现在政策中(Pennells et al.， 2014)。这被认为是公众反对这项技术的主要决定因素，最相关的是核技术以及更多的例子。
Risk perception is a process involving decision making that is extremely personal, this is based on the reference frame articulated by an individual over the time of life along with other elements. Several researches conducted over the last decade make it evident that when the decision making is related to safety and health, the threats that are most pressing are not considered. As per David (2012), this is referred as a gap within risk perception literature (Dorfman et al, 2012). The gap within the risk perception appears to be resulting from the negligence or ignorance, but the psychologists and researchers assert that it is a natural ability which takes into account various factors apart from the facts.
The perception of risk is an assessment that is highly subjective of the likeliness of defined action type to occur and determination of concern associated with the consequences. In order to perceive the risk, evaluation of the likeliness is essential. This comes along with the impact that the negative outcome will cause. This is required for risk perception. The risk perception moves above the individual considering it to be a construct of culture and society in reflection of values, history, symbols and ideology (Jorion, 2010). It follows the specificity and human socially existence variability which the assumption should not be made that ratings and scored on instruments of similar identity possess the same meaning in varied contexts. It was claimed by Adams (1995) that the initiating point of any risk theory is that there should be presence of everyone’s will in taking the risks. It has appeared that the risk perception is present in the policies as a concept of importance in the years of 1960s (Pennells et al., 2014). This was implicated as a primary determinant of opposition from public towards the technology, most relevantly related to the technology of nuclear along with more examples.
