In public policy, the outrage factor is the portion of public opposition to a policy which does not derive from knowledge of the technical details. While policy analysis by institutional stakeholders may focus on risk-benefit analysis and cost-benefit analysis, popular risk perception is not informed by the same concerns, and so the successful implementation of a policy relying on public support and cooperation will need to address the outrage factor when informing the public about the policy. ==Factors== The term "outrage factor" originates from Peter Sandman's 1993 book, ''Responding to community outrage: strategies for effective risk communication''.〔 〕〔 〕 (As of February 2012, (Responding to Community Outrage ) is now online under a Creative Commons license, and may be freely accessed and downloaded.) He gives the formula:〔Sandman, p.1〕 In an interview with ''New York Times'' journalist and Freakonomics author Stephen J. Dubner, Sandman emphasised "the most important truth in risk communication is the exceedingly low correlation between whether a risk is dangerous, and whether it’s upsetting."〔(【引用サイトリンク】title=Risk = Hazard + Outrage: A Conversation with Risk Consultant Peter Sandman )〕 Sandman enumerates several sources of outrage: ;Voluntary vs. coerced:People may object to something compulsory which is less dangerous than something else that they have a choice to refuse, such as a dangerous sport.〔Sandman, pp.14–17〕 ;Natural vs. industrial:A human-made source of risk provides someone to blame for the risk; household radon is less publicly feared than less carcinogenic artificial sources. While there are approximately 21,000 deaths per year in the USA due to radon-induced lung cancers, the EPA struggles to encourage citizens to test their own homes for radiation.〔Sandman, pp.17–19〕 ;Familiar vs. exotic: We worry less about familiar things than things that are out of our experience range. We are very familiar with water and this reduces the impact of the very high number of children that die each year from drowning in swimming pools (The old saying "familiarity breeds contempt' is accurate here). However, if there was a news headline talking about the fatality of scores of children each year due to an excessive intake of Dihydrogen Monoxide (the chemical name for water) the reaction would be very different indeed.〔Sandman, pp.19–23〕 ;Memorable or not:Memorableness may derive from personal experience, news reports, fiction, or iconic images or symbols of something bad. It is a kind of Deja Vu feeling that you know how this is going to turn out even though the actual event you are experiencing may be quite different from your earlier experience.〔Sandman, pp.23–27〕 ;Dreaded or not:Disgust can exaggerate perceived risk: Some topics just send a shudder through us> Shark attacks, cancer, nuclear radiation are all in the category where the fear is not particularly dependent on the specific circumstance being encountered. For example, if a doctor told you that you had cancer but there was a 90% chance of a total recovery with this particular form - you would probably still be more scared than if a doctor told you you had a heart condition with the same chance of total recovery.〔Sandman, pp.27–29〕 ;Chronic vs. catastrophic: People will react far more about 400 people dying in one aircraft crash than 1000 dying in road crashes over a year. Sandman asks that we consider what would happen if all of the people that died of smoking over a year died in one city on one day - and suggests smoking would become illegal overnight.〔Sandman, pp.29–33〕 ;Knowable or not:people take a worst-case approach to uncertainty. Sandman talks of duelling PhDs meaning that when experts disagree the public are likely to believe things could be much worse than either of the expert's claim. If the experts understood this they would realise that agreeing on a range of values rather than arguing would reassure people that there are reasonable limits to what might occur.〔Sandman, pp.33–37〕 ;Controlled by me vs. others:〔Sandman, pp.37–41〕 ;Fair or not:〔Sandman, pp.41–44〕 ;Morally relevant or not:〔Sandman, pp.44–49〕 ;Can I trust you or not:〔Sandman, pp.49–62〕 ;Is the process responsive or not:〔Sandman, pp.62–73〕 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Outrage factor」の詳細全文を読む スポンサード リンク
